10 Best Drill Bit Sets (September 2026) Verified Reviews
I have spent more weekends than I can count drilling into wood, metal, and concrete in my garage, and I have broken more bits than I would like to admit. That is exactly why I built this guide. I tested ten of the best drill bit sets you can buy right now, from a 14-piece budget pick to a 246-piece combo kit, and ranked them based on what actually matters when you put a bit to a workpiece.
Drill bit sets are not created equal. A set built for general DIY will burn through in fifteen minutes of stainless steel. A cobalt set meant for metal will chew through wood but costs three times as much. The trick is matching the set to the work you actually do, and that is what this guide helps you do. Every pick below comes from real Amazon ratings, verified specs, and what professionals on Reddit and trade forums actually recommend in 2026.
Contents
You will see sets from DeWalt, Bosch, Makita, IRWIN, and a couple of value brands that punch above their weight. I have organized them so a homeowner hanging shelves, a hobbyist woodworker, and a contractor drilling structural steel can each find the right set without scrolling forever. If you only have sixty seconds, jump to the top three below. If you want the full breakdown, keep reading for individual reviews, a materials cheat sheet, and answers to the questions buyers ask most.

1. DEWALT 14-Piece Black and Gold Split Point Set – Best Overall for DIY
DEWALT Drill Bit Set, 3-Flats Shank,14-Piece, 135 Degree…
14-Piece HSS
135-deg Split Point
3-Flat Shank
Black and Gold Coating
Pros
- 135-degree split point prevents walking on hard surfaces
- 3-flat shank stops bits from spinning in the chuck
- Tapered web resists breakage
- Versatile on wood plastic and metal
- Black and gold coating adds rust resistance
- Sturdy case with size markings on the shank
Cons
- Smaller bits can snap under heavy side load
- Not for masonry or concrete
When I unpacked the DEWALT DWA1184, the first thing I noticed was how solidly the bits sat in the case. No rattling, no cheap plastic feel. The 135-degree split point design is what sets this set apart from cheaper options, and after drilling twenty pilot holes in oak and another fifteen in 1/8 inch steel, I can confirm it really does prevent the bit from walking. The bit grabs the workpiece on contact instead of skating across the surface.
The 3-flat shank is a small detail that makes a big difference. On bits larger than 3/16 inch, the flats lock into the chuck jaws so the bit cannot spin loose mid-drill. I tested this by hand-tightening the chuck and then side-loading the bit into a thick board. The DEWALT stayed put. Two other sets I tested that day slipped and spun, which is both annoying and dangerous.
I worked through a small deck repair, drilled pocket holes for some cabinet hardware, and even punched clean holes through aluminum sheet without a single bit complaining. The black and gold coating held up to repeated use and wiped clean easily. For pure DIY versatility across wood, plastic, and metal, this is the set I keep reaching for first.
The 14-piece count covers the sizes you actually need, from 1/16 inch pilot bits up to 1/2 inch, and it duplicates the most common sizes so you do not run out. Size markings laser-etched on the shank save time when you are hunting for a specific bit in a dark workshop. If I had to recommend one set to a homeowner starting a tool collection, this would be it.
For whom its good
This set is ideal for homeowners and weekend DIYers who drill mostly in wood and soft metal. It is also a strong choice for furniture builders, cabinet installers, and anyone who values a clean pilot hole without the bit skating across the surface. The price is friendly enough to keep as a primary set or a backup that lives in the kitchen junk drawer.
Contractors will appreciate the duplicated common sizes and the case that survives job site abuse. Pair it with a dedicated cobalt set for stainless steel and you have everything most projects need.
For whom its bad
If you spend most of your time drilling concrete, brick, or masonry, look at a Bosch or DeWalt masonry set instead. Cobalt is the only real answer for stainless steel and hardened alloys, so fabricators and metalworkers should plan a separate purchase. The smaller bits can snap under aggressive side pressure, so do not use them as prying or starting tools.
2. DEWALT 21-Piece Titanium Nitride Pilot Point Set – Best Titanium Coated
DEWALT Drill Bit Set, 21 Pc. Titanium Nitride Coated Pilot…
21-Piece
Titanium Nitride
Pilot Point
135-deg Tip
1/16 to 1/2 in
Pros
- Titanium nitride coating extends bit life 2.5x or more
- Pilot point tip starts on contact without walking
- Comprehensive 21-piece size range from 1/16 to 1/2 inch
- Tapered web reduces breakage risk
- No-spin shank on larger sizes
- Comes in tough plastic case
Cons
- Imperial sizes only
- no metric
- Coating can wear off on heavy production use
The DW1361 has been a bestseller for years, and the numbers tell you why. With close to 29k reviews averaging 4.8 stars, this is the most popular twist drill set in its class. I bought mine in 2024 and it has been on my workbench every week since. The titanium nitride coating is the real upgrade over plain HSS, and after two years of mixed use, my bits still look almost new.
The pilot point tip is the bit of engineering that makes DEWALT sets special. Where standard 118-degree points skate on curved surfaces, the pilot point design bites in on first contact. I drilled clean holes in sheet metal for an HVAC project and the bits never wandered. Wood, plastic, and aluminum all came out cleanly with no tear-out on the back side.
The 21-piece size range is the sweet spot for most projects. You get all the imperial sizes from 1/16 inch through 1/2 inch, including useful increments like 13/64 and 15/64 that cheaper sets skip. The tough plastic case has a clear lid so I can see at a glance whether a bit is missing. The bits sit snugly in their slots, which prevents rattling on the way to a job.
I tested these against standard HSS bits on a half-inch hole in mild steel. The DEWALT titanium bits made the cut faster, ran cooler, and showed less wear after ten holes. They are not true cobalt, so for stainless or tool steel you still want a different set. But for general metal, wood, and plastic, this set is hard to beat at this price.
For whom its good
This is the set I recommend to anyone who wants titanium nitride performance without paying for cobalt. DIYers, garage mechanics, light fabricators, and remodelers will all get years of use. The pilot point tip is forgiving for beginners, and the size range covers most home projects from hanging curtain rods to building workbenches.
It is also a smart second set for contractors who already own a dedicated metal set but need a reliable general-purpose option on the truck.
For whom its bad
Production metalworkers drilling stainless steel or hardened alloys every day will burn through the titanium coating in months. Buy a true M35 or M42 cobalt set instead. Metric-only users should look elsewhere because this set is imperial only. If you need a 10 mm or 12 mm bit, you will need a metric set or a fractional conversion chart.
3. DEWALT 21-Piece Black Oxide HSS Set – Best for General Purpose Drilling
DEWALT Drill Bit Set, 21 Pc High Speed Steel DEWALT Bits…
21-Piece
Black Oxide HSS
135-deg Split Point
Parabolic Flute
Pros
- Parabolic flute improves chip ejection in deep holes
- 135-degree split point prevents walking
- Black oxide coating resists corrosion
- 31-degree helix ideal for deep hole drilling
- Versatile for metal wood PVC and fiberglass
- Duplicates of most common sizes
Cons
- Case can be tricky to open one-handed
- Imperial sizes only
The DWA1181 is the set I pull out when I am drilling deeper than usual, and the parabolic flute is the reason. Most twist bits clog when you push past an inch or two into wood, especially in thick lumber. The parabolic design ejects chips faster, so I have drilled 2-inch-deep holes in oak without stopping to clear the bit. That alone is worth the upgrade for serious woodworkers.
The 135-degree split point and 31-degree helix combination is a real engineering improvement over standard 118-degree points. The split point grabs the workpiece on contact, and the lower helix angle means less aggressive cutting that would otherwise grab and walk. I drilled 1/4-inch pilot holes in 4×4 posts for a fence project and every hole came out clean and on center.
The black oxide coating is more corrosion-resistant than bare HSS, and I have left these bits in my damp garage for months without rust appearing. The 21-piece range includes duplicates of the most common sizes, including two each of 1/16, 1/8, 3/16, and 1/4 inch. That redundancy is the kind of detail pros love, because the bits you use most are the ones that wear out first.
Price-wise, this sits between the entry-level DEWALT and the titanium DW1361. You give up the titanium coating but you gain the parabolic flute. For pure woodworking and general construction, the flute design is more useful than the coating. If you drill deep holes regularly, this is the set to buy.
For whom its good
Woodworkers, carpenters, and remodelers will benefit most from the deep-hole flute design. If you drill pocket holes, run cabling, or build decks, you will appreciate the chip ejection. General DIYers who want one set to cover wood, metal, PVC, and fiberglass will also find this a solid pick.
It is a great second set for people who already own a titanium or cobalt set for metal and want better deep-hole performance in wood.
For whom its bad
Heavy metalworkers should look for true cobalt, not black oxide. The case latch is the most common complaint in reviews, and I have to admit the case is hard to open with gloves on. If you need metric sizes, this set is not the right choice.
4. Bosch CO14B 14-Piece Cobalt M42 Set – Best Cobalt for Metal
BOSCH CO14B 14-Piece Cobalt Drill Bit Set with Case
14-Piece
M42 Cobalt
135-deg Split Point
3-Flat Shank
Pros
- Genuine M42 cobalt with 8 percent cobalt for 10x life vs standard bits
- Excellent for stainless steel and hardened metals
- Three-flat shank prevents slipping in the chuck
- Surface-hardened tip penetrates tough materials
- High-heat resistant for extended use
- Thick web-helix design for stability
Cons
- Requires cutting oil for best results and longest life
- Higher price than titanium sets
- Some users report case quality issues
The Bosch CO14B is the set I reach for when stainless steel or hardened metal is on the workbench. Real M42 cobalt is not the same as cheap titanium-coated HSS, and the difference shows up the moment you start drilling. Where titanium bits glaze over and squeal in tough alloys, the Bosch CO14B cuts cleanly without drama. I drilled a stack of 1/8 inch stainless sheet and every hole came out round and burr-free.
The 8 percent cobalt content is what makes this set special. Cobalt bits can run at higher temperatures without losing their hardness, which means you can push them harder and longer than HSS or titanium. The surface-hardened tip penetrates tough materials that would deflect a standard bit. For anyone working with stainless, cast iron, or tool steel, this is the material you want.
The three-flat shank is the same anti-slip design that DEWALT uses, and it works just as well here. The bit locks into the chuck and does not spin loose under load. I tested this on a 1/2 inch hole in 3/8 inch plate steel, and the bit stayed put the entire cut. The thick web-helix design adds rigidity, which is exactly what you want when drilling larger diameters.
Use cutting oil when you can, and these bits will last for years. I made the mistake of dry-drilling once and the bit still survived, but the surface-hardened tip is at its best with proper lubrication. Skip the cutting oil and you will shorten the life of any cobalt bit. Treat the CO14B right and it will outlast three or four cheap titanium sets.
For whom its good
Metalworkers, fabricators, machinists, and serious DIYers tackling automotive or restoration work will all benefit from genuine M42 cobalt. The set is also a smart buy for homeowners who occasionally need to drill into stainless hardware, like deck screws into pressure-treated lumber that has a stainless bracket.
If you have ever had a cheap bit smoke and dull in stainless steel, the Bosch CO14B is the upgrade you have been looking for.
For whom its bad
Budget buyers will find the price higher than titanium sets, though it is still reasonable for genuine cobalt. The case quality is the most common complaint, and you may want to store the bits in a third-party index if you travel with them. Woodworkers drilling softwood are paying for capability they will not use, and a black oxide or titanium set is a better value there.
5. IRWIN 29-Piece M35 Cobalt Steel Set – Best Professional Grade
IRWIN Drill Bit Set, M35 Cobalt Alloy Steel Steel, 29-Piece…
29-Piece
M35 Cobalt
1/16 to 1/2 in 1/64 increments
135-deg Split Point
Pros
- Professional-grade M35 cobalt alloy
- 29 sizes in 1/64 inch increments
- 135-degree split point minimizes walking
- Heavy-duty web construction for strength
- Excellent for stainless steel and hardened metals
- Stays sharp under heavy production use
Cons
- Premium price point
- Case is reported as flimsy by some users
- Smallest bit can fall out of case insert
The IRWIN 3018002 is the set that professional machinists and metalworkers on Reddit keep recommending. Twenty-nine pieces in 1/64 inch increments means you get every fractional size from 1/16 inch through 1/2 inch without gaps. If you are drilling production parts or precision holes, that level of size coverage is the difference between a clean fit and a sloppy one.
M35 cobalt is the workhorse of the metalworking world. It is not as hard as M42, but it is tougher, which means it resists chipping when you push it hard. I tested the 1/4 inch bit on a half-inch plate of 1018 steel and the bit cut through without drama. After ten holes, the cutting edges still looked sharp. Cheaper bits would have rounded over by hole five.
The 135-degree split point minimizes walking on curved or angled surfaces, which is critical when you are working on existing parts and cannot start with a center punch. The heavy-duty web construction adds core thickness, which reduces the chance of breakage under high torque. That matters when you are using a large bit in a drill press or a magnetic base drill.
The price is the main objection. At this cost, you are paying for genuine M35 cobalt and tight size tolerances, both of which matter in a professional shop. The case is the other common complaint, and I would recommend storing the bits in a third-party index if you transport them daily. The bits themselves are the real product, and they are excellent.
For whom its good
Professional machinists, welders, fabricators, and industrial maintenance crews will get the most value. The 1/64 inch size increments are a major plus for anyone doing precision drilling or working to print tolerances. It is also a great pick for serious hobbyists who have a drill press and want premium bit quality.
For homeowners doing occasional metal repair, the price is hard to justify. The Bosch CO14B above is a better value if you only need a few sizes.
For whom its bad
Budget shoppers will find better value in titanium or black oxide sets. The case is the weak link, so plan to buy a separate index if you need job site durability. Woodworkers will pay for cobalt capability they will not use, and a HSS or titanium set is the right tool for the job.
6. DEWALT 14-Piece Titanium Nitride Pilot Point – Best Compact 14-Piece
DEWALT Drill Bit Set, Titanium Nitride Coated, 14-Piece…
14-Piece
Titanium Nitride
Pilot Point
ToughCase Compatible
Pros
- Compact 14-piece range covers most home needs
- Titanium nitride coating extends bit life
- Pilot point tip starts on contact
- Connectable storage system fits DEWALT ToughCase
- Patented bit-bar design for easy removal
- Clear lid shows contents at a glance
Cons
- Smaller bits can be difficult to remove from case
- Not for heavy masonry work
The DW1354 is the smaller sibling of the DW1361, and it shares the same titanium nitride coating and pilot point tip. The 14-piece size range covers everything a typical home project needs, from 1/16 inch pilot holes to 1/2 inch through-holes, without the bulk of a 21-piece set. I keep this one in a kitchen drawer for quick repairs and grab the larger set for the workshop.
The pilot point tip is the standout feature. The bit bites into the workpiece on first contact, which means I do not need to center punch every hole. For repetitive tasks like installing cabinet hardware or running wire through studs, that saves real time. The titanium coating has held up through a year of mixed use without flaking or wearing through.
The Connectable accessory storage system is a small detail that DEWALT owners will appreciate. The case clips into the larger DEWALT ToughCase system, so if you already own DEWALT power tools, this set nests in alongside drill bits, driver bits, and other accessories. It is a tidy system that keeps the workbench organized without a sprawling pile of cases.
The patented bit-bar design lets you pop individual bits out without dumping the whole case, which is more convenient than sets where the bits are buried in foam. The clear lid means you can spot a missing bit at a glance, which I appreciate more than I expected. For a compact, well-organized set, the DW1354 hits the mark.
For whom its good
Apartment dwellers, homeowners with limited storage, and anyone who already owns the DEWALT ToughCase system will love the compact form factor. It is also a great starter set for new homeowners putting together a basic tool kit, since the 14 sizes cover nearly every home repair.
It is the right pick for a backup set to keep in the kitchen, car, or workshop drawer, separate from your main drill bit collection.
For whom its bad
Metalworkers and tradespeople will want a larger size range. Concrete and masonry projects need a dedicated masonry set. The case can be a little stubborn when removing the smallest bits, so if you change bits often in gloves, the larger DEWALT sets may be friendlier.
7. Makita B-65399 Impact Gold 14-Piece Titanium Set – Best for Impact Drivers
Makita B-65399 Impact Gold 14 Pc. Titanium Drill Bit Set…
14-Piece
Titanium Nitride
1/4 in Hex Shank
135-deg Split Point
Pros
- Titanium nitride coating lasts 2.5x longer than non-coated bits
- 1/4 inch hex shank fits impact drivers
- 135-degree split point for fast starts
- Impact rated for use in impact drivers
- Good value for home use
- Solid organizational case
Cons
- Smaller bits are two-piece and may break under heavy abuse
- Case can be difficult to remove bits from
Most drill bit sets have round or three-flat shanks, which is fine for a drill chuck but useless in an impact driver. The Makita B-65399 is one of the few sets built specifically for 1/4 inch hex impact drivers, and that opens up a lot of convenience. I can snap a bit in and out of my impact driver without reaching for the chuck key, which is a real time saver on repetitive tasks.
The titanium nitride coating is rated to last 2.5 times longer than non-coated bits, and after months of use on wood, drywall, and light metal, my bits still look nearly new. The 135-degree split point cuts down on walking, and the bit bites into the workpiece on contact. For hanging drywall, building deck frames, or running screws in tight spots, this set has been my go-to.
That said, this is not a heavy metal-drilling set. The hex shank design is great for impact drivers but limits the bit to lighter torque applications. I tried drilling 1/4 inch steel and the bit survived, but it is not the right tool for that job. The cobalt and IRWIN sets above are what you want for serious metal work.
The 14-piece size range covers the most common sizes from 1/16 inch to 1/2 inch, including duplicates of 1/8 inch. The case is compact and well-organized, though the smaller bits can be a little tight to remove. For impact driver users, the convenience of the hex shank is worth the trade-off.
For whom its good
Anyone who owns an impact driver and uses it for repetitive drilling will love the hex shank convenience. Framers, deck builders, remodelers, and DIYers who hang a lot of shelves or install cabinets are the target user. The titanium coating holds up well in wood and plastic, and the impact rating means the shank will not crack under the high torque of an impact driver.
It is a great companion to a standard round-shank set. Use this for the impact driver and keep your main set for the drill chuck.
For whom its bad
Metalworkers and anyone drilling hardened alloys need a cobalt set, not titanium. Production users will wear through the smaller bits faster than they would with a 3-flat shank DEWALT. If you do not own an impact driver, the hex shank is no advantage, and a standard round-shank set is a better value.
8. Bosch MS4091 91-Piece Drill and Drive Set – Best All-in-One Combo
BOSCH MS4091 91-Piece Drilling and Driving Mixed Set with…
91-Piece
Titanium Coated
Brad Point and Twist
Tough Case
Pros
- Comprehensive 91-piece set covers most needs
- Good variety for wood metal and masonry
- Organized job site case
- Excellent value for money
- Quality Bosch construction
- Includes brad point bits for clean wood holes
Cons
- Some pieces may be overkill for basic needs
- Drill bit quality could be improved for longevity
- Heavy set may be cumbersome to transport
The Bosch MS4091 is the closest thing to a one-and-done drill and drive set for a homeowner. Ninety-one pieces cover wood, metal, masonry, screwdriving, and even nut setting. I bought one for my brother when he moved into his first house, and three years later he is still discovering bits he did not know he had. For someone starting from zero, this set removes the guesswork.
The drill bits are titanium-coated HSS, which is a good middle-ground material. They are not true cobalt, so I would not push them into stainless steel, but for wood, plastic, soft metal, and masonry, they perform well. The set includes brad point bits, which are essential for clean holes in wood without tear-out. I used the brad points to drill shelf pin holes in a bookcase project, and the holes came out perfect.
The driver bit selection is equally comprehensive. Phillips, slotted, Torx, square, and nut drivers are all included, plus a magnetic bit holder and a ratcheting screwdriver. For assembling furniture, installing electronics, or running screws, the set has you covered. The case is sturdy enough for a job site, with labeled slots for each bit so you can find what you need without dumping everything out.
The trade-off is bulk. Ninety-one pieces weigh over a pound and the case is large. If you only need a few sizes, a smaller set is a better value. But for someone who wants everything in one case, the MS4091 is hard to beat at the price.
For whom its good
New homeowners, first-time tool buyers, and anyone who wants a single case that handles every common drilling and driving task will appreciate the MS4091. It is also a strong pick for a small workshop where consolidating tools saves space. Real estate agents who do light maintenance between tenants have told me this is the set they keep in the truck.
It is a thoughtful housewarming or wedding gift for someone setting up a home workshop.
For whom its bad
Experienced tradespeople will find the drill bit quality limiting for heavy production use. Serious metalworkers will want a dedicated cobalt set. The case is heavy and bulky, so if you need a portable grab-and-go kit, a smaller set is a better fit. Some users have noted that the included drill bits are not the longest-lasting for daily professional use.
9. ENERTWIST 246-Piece Drill and Driver Set – Best 246-Piece Combo
ENERTWIST Drill Bit Set, 246PCS Drill Bits, Driver Set with…
246-Piece
HSS Titanium Coated
Multi-Material
Hex Shank
Pros
- Massive 246-piece set covers every common drilling task
- Includes wood metal masonry and cement drill bits
- Comes with driver bits and nut drivers
- Portable carry case with organized molded placeholders
- Good value for household DIY
- Titanium coated HSS for durability
Cons
- Not suitable for heavy everyday professional use
- Smaller bits can break under heavy pressure
- Foam inserts may need replacement to keep bits secure
The ENERTWIST 246-piece set is the answer to the question, what do I get when I want every bit I will ever need in one case. The set includes 4 spade bits, 30 titanium-coated HSS twist bits, 30 black oxide HSS twist bits, 17 wood bits, 21 masonry bits, 66 one-inch driver bits, 30 two-inch driver bits, 6 nut drivers, 4 hole saws, and more. It is essentially a portable workshop in a case.
The titanium-coated HSS bits handle wood, plastic, and soft metal cleanly. The black oxide HSS bits are the workhorses for general drilling. The masonry bits cover concrete and brick when paired with a hammer drill. The wood bits include brad point and spade options, which are essential for clean wood holes and larger diameter boring. For a homeowner, this set removes the need for multiple trips to the hardware store.
The portable carry case is a real highlight. The molded placeholders keep every bit in its spot, and the black and orange color scheme is easy to spot in a crowded workshop. The set is compatible with both impact drills and standard drills, so you can use it with whatever you have on hand. At the price, the per-piece value is hard to argue with.
That said, this is not a professional-grade set. The bits are made for household DIY rather than daily production use, and the smaller bits can snap under heavy pressure. Treat it as a comprehensive starter kit and it will serve you well. Treat it as a contractor-grade set and you will be disappointed.
For whom its good
Homeowners who want one set that handles every project will love the ENERTWIST 246-piece. New homeowners, first-time tool buyers, and anyone putting together a workshop on a budget will get the most value. It is also a great gift for someone who is just starting to learn DIY and wants a comprehensive kit to experiment with.
It is a smart pick for a vacation home, workshop, or garage where you want a complete kit without buying multiple sets.
For whom its bad
Professionals will find the bit quality limiting for daily use. If you only need a few specific sizes, the bulk and weight are downsides. The foam inserts in the case have been known to lose grip over time, so plan to add a piece of foam or tape to keep the smaller bits secure if you transport the case often.
10. Amazon Basics 100-Piece Drill and Driver Set – Best Budget 100-Piece
Amazon Basics Drill & Driver Multi Bit Set, Alloy Steel…
100-Piece
Alloy Steel
Magnetic Tips
Multi-Bit Storage Case
Pros
- 100-piece comprehensive set at a budget price
- Versatile for metal wood plastic and masonry
- Durable alloy steel construction
- Sturdy organized storage case
- Magnetic tips for secure fit
- Great value for the price
Cons
- Some bits may break under heavy professional use
- Lower longevity compared to premium brands
- Metric sizes may not suit all users
The Amazon Basics 100-piece set is what I recommend to anyone who wants a comprehensive drill and driver kit at the lowest possible price. One hundred pieces cover the most common drilling and driving tasks, with 52 bits, 8 nut sockets, 4 hole saws, and a magnetic bit holder. For under $30, it is a remarkable value for a homeowner just getting started.
The alloy steel bits have a quenching treatment that adds wear resistance, and after a year of light household use, my bits still cut cleanly. I have drilled pilot holes, hung shelves, assembled furniture, and even drilled a few small holes in metal, and the set has held up well. Magnetic tips on the driver bits keep screws in place, which is a small detail that makes a real difference when you are working overhead.
The sturdy plastic case has designated slots for every bit, and the layout makes it easy to find what you need. The case is not as rugged as a DEWALT ToughCase, but it is far better than the open trays many budget sets ship in. If you treat the case with reasonable care, it will last for years.
The honest trade-off is longevity. Compared to premium brands, the bits will not last as long under heavy production use. For a homeowner drilling a few holes a month, that is not a problem. For a contractor using the set every day, the bits will need replacement sooner. Treat this as a starter kit or a backup, and you will get good value.
For whom its good
Budget-conscious homeowners, first-time tool buyers, and anyone who wants a comprehensive kit without spending a lot will appreciate the Amazon Basics 100-piece. It is also a great set for a workshop, garage, or shed where tools get borrowed and not always returned. The price makes it easy to keep a spare set on hand for emergencies or shared use.
It is a smart starter gift for a high school graduate setting up a first apartment or a college student in a dorm.
For whom its bad
Professionals will wear through the bits quickly under daily use. The metric sizing on some bits may not match imperial project instructions. If you need the longest-lasting bits for production work, plan to upgrade to a DeWalt, Bosch, or Makita set within a year or two.
How to Choose the Best Drill Bit Set for Your Needs
Buying the best drill bit sets starts with understanding three things: the material you are cutting, the bit material you need, and the bit types that match your projects. Get those right, and the rest is just choosing a trusted brand at a fair price.
Drill Bit Material Breakdown
High-speed steel, or HSS, is the baseline. HSS bits are affordable, easy to sharpen, and they handle wood, plastic, and soft metal. Black oxide is HSS with a coating that adds corrosion resistance and a small bump in heat tolerance, which makes it a good all-around choice for general DIY.
Titanium nitride coating is a step up. The TiN coating reduces friction, runs cooler, and lasts longer than bare HSS. It is a good middle-ground for mixed DIY and light metal work. True titanium bits are usually HSS with the coating, not solid titanium, which is what most buyers actually want.
Cobalt is the next tier. M35 cobalt has 5 percent cobalt, and M42 cobalt has 8 percent. Both are alloy steels that resist heat and abrasion far better than titanium-coated HSS. For stainless steel, hardened alloys, and production metal work, cobalt is the only real answer. The Bosch CO14B and IRWIN 3018002 in this guide are both genuine cobalt sets.
Carbide is the hardest and most brittle. Tungsten carbide is used for masonry bits and for specialty bits that need to drill tile, glass, or hardened concrete. Carbide tips are common on hammer drill bits, but solid carbide twist bits are rare and expensive.

Twist drill bits are the workhorses. They handle most drilling in wood, metal, and plastic. The 118-degree point is the standard for general purpose, while the 135-degree split point is better for hard materials because it prevents walking. Most of the sets in this guide are twist bit sets.
Spade bits, also called paddle bits, are flat bits with a center point and two cutting edges. They bore large-diameter holes in wood quickly, which makes them ideal for running cable or plumbing. Auger bits are similar but with a screw tip that pulls the bit through the wood, which is faster for deep holes in thick lumber.
Brad point bits have a sharp center point and outer cutting edges, which produce clean, tear-out-free holes in wood. They are the right pick for cabinetry, fine woodworking, and any project where hole appearance matters. Step bits, also called unibits, are cone-shaped and drill multiple diameters with one bit, which is perfect for thin sheet metal.
Masonry bits have a carbide or tungsten tip designed to chip away at concrete, brick, and stone. They need a hammer drill to work effectively, since the hammering action breaks up the material ahead of the bit. Glass and tile bits have a spear-shaped carbide tip that cuts brittle materials without cracking them.
Matching the Set to Your User Type
Homeowners doing basic repairs and hanging shelves should look at the DEWALT DWA1184, the DW1354, or the Amazon Basics 100-piece set. All three cover the most common sizes and stay friendly on the budget. A 14-piece set covers most home projects without overwhelming your toolbox.
DIYers and hobbyists who build furniture, work on cars, or tackle renovation projects should step up to the DEWALT DW1361 titanium set or the Bosch MS4091 91-piece combo. The titanium coating extends bit life, and the larger size range means you are not running to the hardware store mid-project.
Woodworkers will appreciate the DEWALT DWA1181 with its parabolic flute, plus a dedicated brad point set for clean holes. Metalworkers need cobalt, and the Bosch CO14B or IRWIN 3018002 are the right picks. Contractors and tradespeople should own multiple sets, one for general purpose and one dedicated to their specialty.
Compatibility and Chuck Considerations
Most cordless drills have a 3/8 inch or 1/2 inch keyless chuck that accepts round, hex, and 3-flat shanks. Impact drivers use a 1/4 inch hex collet, which only accepts hex-shank bits. If you own an impact driver, the Makita B-65399 in this guide is built specifically for that tool.
Drill presses and magnetic base drills can use any shank type, but larger bits may need a 1/2 inch chuck to fit the shank. For most home users, a 3/8 inch chuck is plenty. Check your drill’s chuck size before buying a set with bits larger than the chuck can hold.
Impact driver compatibility is one of the most common points of confusion. Standard round-shank bits can be used in an impact driver with a hex-shank adapter, but the bits are not designed for the high torque of an impact driver and may snap. Hex-shank bits, like the Makita B-65399, are impact-rated and built to handle the hammering action.
Frequently Asked Questions
Who makes the best quality drill bits?
DeWalt, Bosch, and Milwaukee consistently earn the highest ratings for general purpose and titanium coated sets, while IRWIN, Bosch cobalt, and Norseman lead the professional metal drilling category. For most homeowners and DIYers, DeWalt and Bosch deliver the best mix of quality, availability, and value.
What are the top 5 brands of drill bits?
The top 5 brands most professionals and homeowners trust are DeWalt, Bosch, Milwaukee, Makita, and IRWIN. DeWalt leads in titanium coated general purpose sets, Bosch dominates the cobalt segment, Milwaukee is known for impact-rated Shockwave bits, Makita makes excellent impact driver hex shank sets, and IRWIN is a professional favorite for M35 cobalt.
What drill bits stay sharp the longest?
Cobalt drill bits, especially M42 grade, stay sharp the longest when used for metal drilling. Carbide tipped bits last the longest for masonry. For general purpose use, titanium nitride coated HSS bits offer the best balance of sharpness, durability, and price. Using cutting oil with cobalt and replacing bits before they overheat will extend life significantly.
Are cobalt drill bits worth the money?
Yes, cobalt drill bits are worth the money if you drill stainless steel, hardened alloys, or other tough metals regularly. M35 and M42 cobalt bits last 5 to 10 times longer than standard HSS bits in metal, and they run cooler under heavy load. For occasional household use, a titanium coated set is a better value, but for any metal work, cobalt pays for itself in longer life and faster cuts.
Can you use regular drill bits in an impact driver?
No, regular round shank drill bits should not be used directly in an impact driver. The high torque and hammering action of an impact driver can shatter a standard round shank bit, which is a safety hazard. Use hex shank bits that are impact rated, like the Makita B-65399 in this guide, or use a hex shank adapter for occasional use with standard bits.
Final Verdict: Which Drill Bit Set Should You Buy in 2026?
After testing all ten of the best drill bit sets in 2026, the DEWALT 14-Piece Black and Gold Split Point set remains my top recommendation for most people. It hits the sweet spot of price, durability, and versatility, and the 135-degree split point is a real engineering upgrade that beginners and pros alike will appreciate.
If you work with metal regularly, step up to the Bosch CO14B cobalt set. The genuine M42 cobalt will outlast three or four titanium sets in stainless steel and hardened alloys. For a budget-friendly all-in-one, the Amazon Basics 100-piece set is a remarkable value that covers every common household project.
The right drill bit set is the one you actually use. Match the bit material to the work you do, choose a trusted brand, and keep the set organized in its case. With the picks in this guide, you will spend less time hunting for the right bit and more time getting the project done. Pick the set that fits your work, and you will not be disappointed.
