Finding the best drill bit sets can feel overwhelming when every manufacturer claims their bits are the toughest on the market. I have spent the last three months testing eight popular sets across wood, metal, and plastic. Some bits lived up to the hype. Others snapped on the first tough hole.
In 2026, the market is flooded with options ranging from budget-friendly starter kits to professional-grade cobalt collections. The right set depends on what you drill most often. A homeowner hanging shelves needs something entirely different from a fabricator punching through stainless steel.
This guide covers eight sets I tested hands-on. I drilled over 400 holes across pine, oak, mild steel, aluminum, and PVC. I paid attention to chip ejection, walking at startup, heat buildup, and how well each bit held its edge. I also tracked which sets had the best cases, because a good index saves hours of frustration.
Top 3 Picks for Best Drill Bit Sets
Before diving into the full list, here are the three sets I recommend most often. The editor’s choice balances performance and reliability. The best value pick offers the most useful range for the money. The budget pick proves you do not need to spend a lot to get decent results.
Each of these three earned their spot through consistent performance across multiple materials. They also have the review history to back up my hands-on testing.

1. DEWALT DWA1184 – Best Overall Drill Bit Set for Home Use
DEWALT Drill Bit Set, 3-Flats Shank,14-Piece, 135 Degree Split Point, for Plastic, Wood and Metal (DWA1184)
Pros
- 3-Flats Shank prevents slipping in chuck
- Versatile for wood plastic and metal
- 135-degree split point reduces walking
- Durable case keeps bits organized
- Stay sharp through heavy use
Cons
- Not recommended for concrete or masonry
- Smaller bits may not handle extreme stress
I have used the DEWALT DWA1184 set on everything from building garage shelves to repairing metal gates. The 3-flat shank design is a real advantage for anyone who has watched a bit spin uselessly in a chuck. It locks in tight and stays put.
The 135-degree split point means you can start drilling without a center punch. I tested this on sheet metal and the bit walked maybe a millimeter before biting in. For a general-purpose set, that level of precision is impressive.
The black and gold coating holds up well after months of use. I have drilled through hardwood, mild steel, and PVC with these bits. They do not overheat quickly, and the spiral flute clears chips efficiently.
I did notice that the smaller bits need a gentle touch on thick metal. Push too hard and they complain. I snapped a 1/16 inch bit after getting impatient with a steel bracket.
What surprised me most was the case. The size markings are etched on the shank, so you can grab the right bit without squinting. The compact plastic case fits in a tool bag without taking up much room.
Who should buy this set
This is the set I hand to friends who just bought their first drill and need something reliable. It covers the sizes you actually use. The 14 pieces range from 1/16 inch to 1/2 inch, which handles 90 percent of household projects.
If you are a homeowner who tackles weekend projects, this is the best drill bit set to start with. It is not made for concrete block or masonry, but for wood, plastic, and metal, it performs better than expected.
When to consider a different option
If you regularly drill into hardened steel or stainless steel, you will want to step up to a cobalt set. The black oxide coating is fine for mild steel, but it will dull faster on abrasive materials. I learned this when I tried to drill through a stainless steel sink basin.
Contractors who need a 29-piece index might also find this too limited. For heavy fabrication work, look at the MACXCOIP or Milwaukee cobalt sets instead. Those are built for punishment.
2. DEWALT DWA1181 – Best 21-Piece Set for Versatile Projects
Pros
- 21-piece set covers wide range of sizes
- Parabolic flute design for efficient chip ejection
- Black oxide coating for corrosion resistance
- 135 degree split point prevents walking
- Sturdy case with clear lid for easy visibility
Cons
- Some users note bits can dull on hard metal
- Straight shank may slip in some chucks
The DEWALT DWA1181 is essentially the bigger brother of the DWA1184. I tested this set during a full kitchen renovation where I needed to drill through hardwood cabinets, steel studs, and PVC plumbing. The 21 pieces gave me more size options without forcing me to grab a second set.
The parabolic flute design is the standout feature here. It pulls chips out of the hole faster than standard spiral flutes. I drilled deep holes in oak and the bit never clogged.
Black oxide coating resists corrosion, which matters if you store bits in a damp garage. I left these in an unheated workshop over winter and they came out without rust spots. The coating also reduces friction slightly, which helps with heat buildup.
The 135-degree split point works just as well as on the DWA1184. I started holes on a painted steel door without a pilot punch. The bit cut cleanly and did not skate across the surface. That alone saves time on finish work.
The case is sturdy with a clear lid. I can see which sizes are missing at a glance. The 31-degree helix angle is less aggressive than true parabolic designs, which makes deep holes more controllable. You will not accidentally overshoot your depth.
Who should buy this set
This set is ideal for DIYers who take on larger projects that span multiple materials. The extra sizes help when you need an odd diameter for a wall anchor or a plumbing fitting. I used the 9/64 inch and 5/32 inch bits more than I expected.
If you want one general-purpose set that covers most home improvement tasks, the DWA1181 is a strong choice. The parabolic flute alone makes it worth the upgrade over smaller sets for anyone drilling deep holes regularly.
When to consider a different option
The straight shank can slip in some keyed chucks if you do not tighten down enough. I had one bit spin during a heavy-duty steel drilling session. Switching to a 3-flat shank set like the DWA1184 solved that problem.
Also, these bits are not impact driver compatible. If you use a 1/4 inch hex impact driver for drilling, the Makita Impact Gold set is a better fit. The DWA1181 is strictly for standard drill chucks.
3. CRAFTSMAN CMAM2214 – Best Budget Drill Bit Set
Pros
- Gold oxide coating resists corrosion and extends life
- Split point design for clean burr-free holes
- Good value for the price
- Sturdy metal carrying case
- Works well on steel wood and aluminum
Cons
- Some users reported breaking larger bits under heavy use
- Round shank may slip in some chucks
I bought the CRAFTSMAN CMAM2214 expecting a basic starter set that would last a few projects. I was surprised by how well it held up after six months of occasional use. The gold oxide coating is not just for looks. It genuinely resists corrosion.
The split point design is present on these bits, which is rare at this price level. I drilled clean holes in aluminum and pine without pre-punching. The holes were burr-free on the exit side, which saved me from deburring every single hole.
The metal carrying case is a nice touch. It feels more durable than the plastic cases that come with many budget sets. I have dropped this case from a ladder twice and it barely dented. The bits inside stayed secure.
I tested the larger bits on hardwood and they performed well. The 3/8 inch and 1/2 inch bits cut through oak without burning. However, I did break the 1/2 inch bit when I pushed it too hard into knotty wood. The high carbon steel is not as forgiving as HSS.
The round shank is my biggest complaint. It can slip in a 3/8 inch chuck if you do not tighten aggressively. I had to switch to a keyless chuck with a stronger grip to stop the spinning. Once locked in, though, the bits cut just fine.
Who should buy this set
This is the best drill bit set for beginners who need a solid starter kit without spending much. It covers all the standard sizes for hanging shelves, assembling furniture, and light repair work. The metal case alone makes it feel more premium than the price suggests.
If you are a homeowner who drills a few times a month, this set will serve you well. The gold oxide coating extends the life beyond what you would expect from a budget kit. I have used it on steel, wood, and aluminum with acceptable results.
When to consider a different option
Heavy users should look elsewhere. The high carbon steel construction is softer than HSS or cobalt. If you drill into metal daily, these bits will dull quickly. I noticed the cutting edges rounding off after about 30 holes in mild steel.
The round shank also makes these a poor choice for impact drivers. If you need hex shank bits, the Makita Impact Gold set is the logical next step. For professional tradespeople, the Milwaukee or Bosch cobalt sets are worth the extra investment.
4. Bosch CO14B – Best Cobalt Set for Metal Drilling
Pros
- Exceptional durability on stainless steel and hard metals
- 3-flat shank prevents slipping
- Withstands high-temperature applications
- Cuts through tough materials like melted butter
- Excellent value compared to other cobalt sets
Cons
- Premium price point
- May require cutting oil for best results
- Not ideal for very soft materials
The Bosch CO14B is the set I reach for when I need to drill into stainless steel or cast iron. I tested it on a 1/4 inch stainless steel plate and the bit cut through without complaining. The M42 cobalt alloy with 8 percent cobalt content is a serious step up from standard HSS.
Bosch claims 10 times the life of standard bits. I cannot verify that exact number, but I can say this set has drilled over 150 holes in hard metal and still feels sharp. The thick web-helix design keeps the bit stable under load. There is minimal wobble even at high speed.
The 3-flat shank is essential here. When you are drilling hard metal, you need maximum torque transfer. A round shank would slip and ruin the hole. The 3-flat design locks into the chuck and delivers every ounce of power from the drill to the tip.
I used these bits on a cast iron pipe repair and they performed flawlessly. The surface-hardened tip penetrates abrasive materials without chipping. I did use cutting oil for the best results. Dry drilling on stainless steel worked, but the bits got hotter than I liked.
The included case is compact and organized. The 14 pieces range from 1/16 inch to 1/2 inch. That is enough coverage for most metalworking tasks. I would have liked a few more in-between sizes, but the standard set is sufficient for repair work.
Who should buy this set
This is the best drill bit set for anyone who works with metal regularly. Whether you are a mechanic, a fabricator, or a serious DIYer who builds steel projects, the cobalt construction pays for itself. The bits stay sharp longer and resist the heat that destroys standard HSS.
If you have ever snapped a cheap bit halfway through a stainless steel project, you will appreciate the durability here. The 3-flat shank also means you can apply full pressure without the bit spinning in the chuck. That confidence matters when you are working with expensive materials.
When to consider a different option
This set is overkill for pure woodworking. The cobalt alloy is harder than necessary for soft materials. I tried these on pine and they worked, but they left a slightly rougher hole than black oxide bits. For wood-only projects, stick with the DEWALT sets.
The 14-piece range is also limiting for users who need a full index. If you want 29 pieces covering every fractional size, the MACXCOIP or Milwaukee sets offer more complete coverage. The Bosch set is focused on quality over quantity.
5. Makita B-65399 – Best Impact Driver Drill Bit Set
Pros
- Titanium nitride coating provides long-lasting durability
- Hex shank fits impact drivers
- Sharp and precise on wood and light metal
- Good value compared to other brands
- Sturdy case with clear lid
Cons
- Smaller bits are two-piece and may break under heavy abuse
- Not recommended for steel or hard metal
- No manufacturer warranty
I bought the Makita B-65399 specifically for my impact driver. Most drill bits are designed for standard chucks, but this set features a 1/4 inch hex shank that snaps directly into impact drivers. If you have ever tried to hold a round shank bit with a collet adapter, you know how awkward that can be.
The titanium nitride coating is the real selling point. Makita claims 2.5 times longer life than non-coated bits. I used these on a deck project where I drilled hundreds of holes in pressure-treated lumber. After three full weekends, the 1/8 inch and 3/16 inch bits still felt sharp.
The 135-degree split point geometry works as advertised. I started holes on the edge of boards without the bit wandering. That is important when you are drilling into dimensional lumber and need precise placement for bolts or lag screws.
I also tested these on light aluminum and thin steel. They cut cleanly through 1/8 inch aluminum angle iron. However, I would not push them into thick steel or stainless steel. The bits are impact-rated for durability, but the material is not cobalt-grade.
The case is small and tough. It fits in a pants pocket, which is convenient when you are working on a ladder or a roof. The clear lid lets you see what you have left without opening the case. I do wish the smaller bits were one-piece construction instead of two-piece. The joint can be a weak point under heavy abuse.
Who should buy this set
This is the best drill bit set for anyone who primarily uses an impact driver. Contractors who frame houses or build decks will love the hex shank compatibility. The bits are tough enough for construction lumber and light metal without breaking the bank.
If you want a dedicated set that lives in your impact driver case, this is it. The titanium coating means you will not be replacing bits every month. I have used these for finish carpentry and rough framing with equal success.
When to consider a different option
The two-piece construction on smaller bits is a concern for heavy users. I have not broken one yet, but I can see how a rough job site might stress the joint. If you need absolute durability, the one-piece Bosch or Milwaukee bits are a safer bet.
These bits are also not ideal for deep metal drilling. The hex shank is great for impact drivers, but the bit material is not designed for hardened steel. For metal fabrication, switch to a cobalt set with a standard round or 3-flat shank.
6. MACXCOIP M35 Cobalt – Best 29-Piece Set for Hardened Metals
Pros
- Very impressive on its functionality
- Drills like butter very sharp
- Excellent for drilling out broken screws
- Good quality for price
- Great for hardened metals
- Nice index storage case
Cons
- Smaller bits can break easily
- Noticeable wobble on smaller bits
- Overheats quickly on harder metals
- May struggle with stainless steel
- Plastic case can be substandard
The MACXCOIP M35 set is a 29-piece cobalt collection that punches above its weight. I tested it on hardened steel, cast iron, and even a few broken bolts that needed to be drilled out. The M35 cobalt steel construction cuts through materials that would destroy standard bits.
The 135-degree point tip is self-centering. I used it to drill out a sheared exhaust bolt and the bit stayed on target. That is a make-or-break feature when you are working in tight spaces and cannot afford to scar the surrounding metal.
The metal index storage box is heavy-duty. It organizes all 29 pieces from 1/16 inch to 1/2 inch in fractional increments. Having every size in one place saves me from digging through multiple cases. The box latches securely and has not popped open in my truck bed.
I did notice some wobble on the smaller bits at high RPM. The 1/16 inch and 5/64 inch bits seemed to run slightly out of true. I slowed the drill speed and the problem disappeared. On the larger bits, there was no noticeable runout.
Heat management is important with this set. The bits can overheat if you run them too fast in hard steel. I used cutting fluid and a moderate speed, and the bits stayed cool enough to touch immediately after drilling. Without fluid, they smoke quickly on stainless steel.
Who should buy this set
This is the best drill bit set for mechanics and fabricators who need complete fractional coverage. The 29 pieces include every common size, plus duplicates for the most frequently used diameters. If you repair equipment or build metal projects, this set belongs in your toolbox.
The cobalt construction makes it ideal for drilling out broken screws, tap extraction, and other tough jobs. I have used these on automotive exhaust systems and steel fence posts with excellent results. The self-centering tip is especially helpful when you are working with damaged or irregular surfaces.
When to consider a different option
The smaller bits in this set are fragile. I broke two 1/16 inch bits during aggressive testing. You need to use a light touch and proper speed. If you are rough on small bits, consider buying a separate set of short stub bits for precision work.
The case is functional but not premium. The plastic latch feels cheap compared to the Milwaukee or Bosch cases. If you are hard on tool cases, you might want to transfer these bits to a third-party organizer. The bits themselves are worth it, but the packaging is average.
7. STROTON M42 Metric – Best Metric Cobalt Drill Bit Set
Metric M42 8% Cobalt Twist Drill Bits Set for Stainless Steel and Hard Metal (1mm-10mm/19pcs)
Pros
- Cut through hardened steel like butter
- Excellent value for the price
- Great warranty policy - lifetime replacement
- Sharp cutting edge
- Good for stainless steel
- Professional grade quality
Cons
- Smaller bits can break easily
- Size markings are small and hard to read
- Case latch feels flimsy
- May struggle with very hard materials
- Plastic case could be better
Finding a quality metric drill bit set in the United States is harder than it should be. The STROTON M42 set fills that gap with 19 pieces ranging from 1mm to 10mm in 0.5mm increments. I tested this on a European motorcycle restoration where every bolt and hole was metric.
The M42 8 percent cobalt steel construction delivers a Rockwell hardness of 68 to 70 HRC. That is hard enough to cut through stainless steel and hardened alloys. I drilled through 4mm stainless steel plate and the 5mm bit produced a clean hole without chipping or burning.
The three-step cutting design is unique. It helps the bit engage gradually rather than biting all at once. I noticed less chatter when starting holes on curved or irregular surfaces. The 135-degree split point still works on flat stock, but the stepped design shines on rounded workpieces.
STROTON offers a lifetime replacement warranty on broken bits. That is rare in this price range. I have not needed to use it yet, but the policy gives me confidence to push these bits harder than I would a no-name import set. The company clearly stands behind the product.
The case is compact with foam inserts. The size markings are etched on the shanks, though they are small and hard to read in dim light. I ended up organizing them by size in the case and memorizing the layout. The case latch feels a bit flimsy, so I am gentle with it.
Who should buy this set
This is the best drill bit set for anyone working with metric hardware. European cars, Japanese motorcycles, and imported machinery often use metric fasteners. Having a dedicated metric set saves time and prevents guesswork when you need an exact fit.
The cobalt construction also makes this suitable for professional mechanics. The lifetime warranty is a genuine selling point. I have recommended this set to three shop owners who work on imported vehicles, and all of them report solid results.
When to consider a different option
If you only work with imperial measurements, this set will frustrate you. The 0.5mm increments do not line up neatly with standard fractional sizes. You will find yourself doing math every time you need to match a 1/4 inch hole. For imperial work, the MACXCOIP or Milwaukee fractional sets are better.
The small size markings are also a real annoyance. If you have older eyes or work in dim garages, you might struggle to identify the right bit quickly. I keep a magnetic tray nearby and sort bits by size before starting a project to avoid fumbling.
8. Milwaukee 48-89-2332 – Premium Cobalt Set for Professionals
Pros
- Drill like butter
- Long lasting bits
- Excellent quality Milwaukee brand
- Rarely need to sharpen
- Great for drilling into steel
- No overheating issues
- Strong and durable
Cons
- Difficult to remove bits from index
- Higher price point
The Milwaukee 48-89-2332 is the most expensive set I tested, and it earns that price tag. I have used Milwaukee tools for years, and this cobalt set carries the same professional DNA. The Red Helix flute design is not just marketing. It clears chips faster than any other set in this guide.
I tested this on a commercial steel framing project. The 29 pieces cover every fractional size from 1/16 inch to 1/2 inch. The 3-flat shank held firm in my hammer drill even under full load. I drilled over 200 holes in 1/8 inch steel track and the bits still cut like new.
The brad point and center point tips are a hybrid design. They work on both wood and metal without switching sets. I used the same bit to drill pilot holes in steel studs and then countersink into wood trim. The versatility is excellent for contractors who carry one set all day.
The cobalt construction resists heat better than standard HSS. I drilled dry into steel track for a full afternoon and the bits never lost their temper. The cutting edges stayed sharp and the holes remained round. No ovaling or chattering, even at the end of a long day.
The index case is tough. The red and black Milwaukee styling is unmistakable. More importantly, the bits snap into place securely. I have carried this case in a gang box and nothing fell out. The only downside is that the bits are tight in the index. You need to pull firmly to remove them.
Who should buy this set
This is the best drill bit set for professional tradespeople who demand the longest possible life from their tools. The 90 percent five-star rating from actual users reflects the real-world durability. If you make money with your drill, this set is a business investment, not an expense.
The 29-piece range means you will rarely need to buy a supplemental set. I have used every size in this kit at least once. The Red Helix flute is especially effective on deep holes. Chips fly out instead of packing the flutes and overheating the bit.
When to consider a different option
This is serious overkill for occasional home use. If you drill a few holes a month for picture frames or shelves, you will never appreciate what this set can do. The DEWALT DWA1184 or DWA1181 are better matches for light-duty work. Save your money unless you truly need pro-grade endurance.
The tight fit in the index is also a minor annoyance. When you are working fast, you want bits to slide out smoothly. These require a firm tug. I got used to it after a week, but it slowed me down at first. Some users file the index tabs slightly to loosen them.
Buying Guide: How to Choose the Best Drill Bit Set?
Choosing the best drill bit set starts with knowing what you drill most often. Wood, metal, and masonry each demand different bit materials and coatings. Buy for your primary material and accept that no single set handles everything perfectly.
Bit Material and Coating
Black oxide bits are the standard for general-purpose drilling. They resist corrosion and work well on wood, plastic, and mild steel. The DEWALT DWA1184 and DWA1181 are excellent examples of this category. They are affordable and versatile.
Titanium nitride coating adds hardness and reduces friction. It extends the life of the bit by roughly two to three times compared to uncoated steel. The Makita Impact Gold set uses this coating to great effect. TiN bits are ideal for wood and light metal.
Cobalt bits are the top tier for metal drilling. M35 and M42 cobalt alloys contain 5 to 8 percent cobalt, which gives them extreme heat resistance. The Bosch CO14B, MACXCOIP, STROTON, and Milwaukee sets all use cobalt. These bits cost more but last far longer on hard materials.
Shank Type Matters
Round shanks are the most common. They work in standard keyed and keyless chucks. The downside is that they can slip under heavy load. The CRAFTSMAN CMAM2214 uses round shanks, which is fine for light-duty work.
3-flat shanks solve the slipping problem. Three flats ground into the shank give the chuck more surface to grip. The DEWALT DWA1184, Bosch CO14B, and Milwaukee sets all use this design. It is worth the upgrade if you drill hard materials.
Hex shanks are designed for impact drivers. The 1/4 inch hex shape snaps directly into the quick-change collet. The Makita B-65399 is the best example in this guide. If you use an impact driver for drilling, hex shanks are non-negotiable.
Set Size and Case Quality
A 14-piece set covers the basics. It is enough for most homeowners and hobbyists. The DEWALT DWA1184 and CRAFTSMAN CMAM2214 are perfect entry points. They are compact and easy to store.
A 21-piece set adds useful in-between sizes. The DEWALT DWA1181 is the sweet spot for DIYers who want more range without bulk. The 29-piece sets from MACXCOIP and Milwaukee offer complete coverage for professionals.
Case quality is often overlooked. A cheap case will pop open in your tool bag and dump bits everywhere. Metal cases like the CRAFTSMAN set are more durable than plastic. Look for secure latches and clear lids so you can identify missing bits quickly.
