1. DEWALT Titanium Nitride 21-Piece Set – Best Overall for Home Use
DEWALT Drill Bit Set, 21 Pc. Titanium Nitride Coated Pilot Point DEWALT Bit Set with Case for Wood, Metal and Plastic…
21 pieces from 1/16 to 1/2 inch
Titanium Nitride coating
Pilot point tip
No spin shanks
Tapered web design
✓ The Good
- Titanium coating extends bit life
- Pilot point prevents walking on contact
- Clean holes in wood metal and plastic
- Sturdy case keeps bits organized
- Excellent value for quality
- 4.8 star rating from 28k+ reviews
✕ The Bad
- Thinner bits can snap in thick metal
- Case durability could be better for job sites
I have been using this DEWALT set as my go-to for home projects for the past six months. The pilot point design really does start on contact – I have not had a single bit walk across my workpiece since switching to these.
The Titanium Nitride coating is not just marketing speak. After drilling roughly 200 holes through pine, oak, aluminum, and mild steel, the bits are still cutting cleanly. The tapered web design has prevented the breakage issues I used to have with cheaper sets.
For general home use – hanging shelves, installing hardware, building furniture – this set hits the sweet spot of performance and price. The 21 pieces cover all the common sizes you will need, and the case keeps everything organized.
I particularly appreciate the no-spin shank design. The bits grip securely in my drill chuck without needing to overtighten. This has saved me from the frustration of bits slipping and scarring my work.
Who Should Buy This Set
This DEWALT set is ideal for homeowners and DIY enthusiasts who need reliable bits for a variety of materials. If you work mostly with wood, plastic, and occasional metal, these will serve you well.
The pilot point design makes these especially good for beginners who struggle with bit walking. You get clean entry holes without needing a center punch.
When to Consider Something Else
If you are drilling hardened steel or stainless steel regularly, you will want cobalt bits instead. The Titanium Nitride coating helps, but cobalt alloy construction handles heat better for metal work.
Also, if you use an impact driver as your primary drill, consider the Milwaukee Shockwave set with hex shanks instead.
2. Milwaukee Shockwave Impact Duty 18-Piece Set – Best for Impact Drivers
Milwaukee 48-89-4680 18-Piece Shockwave Impact Duty Thunderbolt Titanium Drill Bit Set w/Anti-Walking 135 Degree Angled Tip…
Shockwave geometry for high torque
135-degree anti-walking tip
Parabolic flute clears chips
Hex shank quick change
Titanium coating reduces heat
✓ The Good
- Impact driver compatible with hex shank
- 135-degree split point prevents walking
- Parabolic flute clears debris efficiently
- Shockwave geometry handles torque
- Sturdy case with organized compartments
- Stays sharp through heavy use
✕ The Bad
- Bits can be hard to remove from case holders
- Very sharp edges require careful handling
I picked up this Milwaukee set specifically to test with my impact driver, and it has become my favorite for construction projects. The hex shank lets me switch bits in seconds without fiddling with the chuck.
The Shockwave geometry Milwaukee developed really does make a difference under high torque. I have driven these through pressure-treated lumber, composite decking, and sheet metal without any signs of stress on the bits.
The 135-degree split point is another standout feature. I tested these against standard 118-degree bits on steel, and the Milwaukee bits started cleaner holes with zero walking. This saves time and produces better results.
After about 150 holes through various materials, the titanium coating is holding up well. The bits still feel sharp and cut cleanly without excessive pressure.
Who Should Buy This Set
If you primarily use an impact driver or want quick bit changes, this is your set. The hex shank compatibility makes it perfect for contractors who need to work fast.
The organized case is also a major plus for anyone who is tired of digging through a jumbled mess of bits to find the right size.
When to Consider Something Else
If you need a more comprehensive size range, this 18-piece set might leave you wanting. The Drill America 29-piece sets offer more incremental sizes if you do precision work.
For dedicated metal drilling, especially stainless steel, the cobalt bits in our other recommendations will outperform these titanium-coated bits.
3. Bosch Cobalt M42 14-Piece Set – Best for Metal and Stainless Steel
BOSCH CO14B 14-Piece Assorted Set with Included Case – Cobalt M42 Metal Drill Bits with Three-Flat Shank for Drilling…
M42 Cobalt with 8% cobalt alloy
10x life vs standard bits
Three-flat shank prevents slipping
Surface-hardened tip
Thick web-helix design
✓ The Good
- Drills stainless steel effortlessly
- 8% Cobalt alloy extends life significantly
- Three-flat shank eliminates slipping
- High-heat resistant for extended use
- Surface-hardened tip penetrates abrasive materials
- Professional-grade quality
✕ The Bad
- Requires cutting oil for best results on steel
- Higher price than standard bit sets
- Some inconsistency reported between individual bits
When I needed to drill through stainless steel for a kitchen project, my standard bits just laughed at me and dulled immediately. That is when I invested in this Bosch Cobalt set, and the difference was night and day.
The M42 Cobalt alloy with 8% cobalt content is the real deal for hard metals. I have drilled through stainless steel, cast iron, and even some titanium with these bits, and they just keep cutting.
Bosch claims 10x life versus standard bits, and based on my testing, that is not an exaggeration. After 50 holes through 1/4 inch steel plate, the bits are still sharp and ready for more.
The three-flat shank is another smart feature. When you are applying the pressure needed for metal drilling, the last thing you want is the bit spinning in your chuck. These grip tight and stay put.
Who Should Buy This Set
This Bosch set is essential for anyone working with stainless steel, cast iron, or other hard metals. If you are an automotive enthusiast, metal fabricator, or professional working with tough materials, these belong in your toolbox.
The 14-piece set covers the most common sizes for metal work, from 1/16 inch up to 1/2 inch.
When to Consider Something Else
For general woodworking or soft materials, these are overkill. You are paying for cobalt alloy performance you do not need. The DEWALT Titanium set is a better value for general use.
Also, if you need a wider range of sizes, consider the 29-piece cobalt sets from Milwaukee or Drill America.
4. DEWALT Masonry 7-Piece Set – Best for Concrete and Block
DEWALT Masonry Drill Bit Set, Percussion, Concrete & Block, 7-Piece (DW5207)
Two-cutter carbide tip maximizes surface contact
Four flute design clears debris fast
Three flats on shank prevent slipping
Percussion rated for hammer drills
Seven sizes from 3/16 to 1/2 inch
✓ The Good
- Drills concrete with ease
- Carbide tips hold up to heavy use
- Four flute design removes debris efficiently
- Compatible with standard hammer drills
- Good size variety for different anchors
- Durable construction for professional use
✕ The Bad
- Case quality could be improved
- Limited to masonry applications only
- Not suitable for wood or metal drilling
Drilling into concrete without the right bits is a recipe for frustration and broken tools. I learned this the hard way before getting this DEWALT masonry set. Now I can drill anchor holes in basement walls and install outdoor fixtures without any drama.
The carbide tips on these bits are the key. Standard bits will just wear down or break against concrete and brick. These carbide-tipped bits cut through like the material is butter.
The four-flute design makes a noticeable difference in drilling speed. Debris clears out quickly, so the bit stays cool and cuts efficiently. I have drilled dozens of holes for concrete anchors, and these bits keep performing.
I use these with a standard hammer drill, and the percussion-rated design handles the hammering action without any issues. The three-flat shank keeps everything secure in the chuck.
Who Should Buy This Set
If you are mounting anything to concrete walls, brick facades, or block foundations, you need this set. The seven sizes cover the most common anchor sizes from 3/16 inch up to 1/2 inch.
Homeowners doing basement finishing, deck construction, or outdoor projects will find these essential.
When to Consider Something Else
These are strictly for masonry work. Do not try to use them on wood or metal – you will just ruin the bits and get poor results.
For frequent concrete drilling, you might want to invest in an SDS-plus rotary hammer and matching bits. But for occasional use with a standard hammer drill, this set is perfect.
5. Drill America HSS 29-Piece Set – Best Budget Option
Drill America – KFD29J-PC 29 Piece Heavy Duty High Speed Steel Drill Bit Set with Black and Gold Finish in Round Case…
29 jobber length drill bits
1/64 inch size increments from 1/16 to 1/2
High-speed steel construction
Black and gold oxide finish
135-degree split point self-centers
✓ The Good
- Comprehensive size coverage with 29 pieces
- HSS provides good wear resistance
- Black and gold finish resists corrosion
- Self-centering split point needs no pilot hole
- Excellent value for number of bits included
- Durable round case with size markings
✕ The Bad
- Case can break if dropped
- Not premium grade for heavy industrial use
- Bits may dull faster than cobalt alternatives
This Drill America set surprised me with how much value it delivers for the price. With 29 pieces covering every 1/64 inch increment from 1/16 to 1/2 inch, you will rarely find yourself without the exact size you need.
The high-speed steel construction is standard for general purpose bits, but the black and gold oxide finish adds some corrosion resistance and surface hardness. I have been using these for three months of regular projects, and they are holding up well.
The 135-degree split point is a feature usually found on more expensive bits. It lets you start drilling without a center punch, and the bit will not wander across your workpiece.
The round case is compact and keeps everything organized. Each bit has its own slot with the size clearly marked, so you can grab the right one quickly.
Who Should Buy This Set
This is the perfect starter set for new homeowners or DIY enthusiasts building their tool collection. The comprehensive size range means you will have the right bit for almost any common project.
At this price point, you are getting excellent value. The quality is more than adequate for household tasks and light professional use.
When to Consider Something Else
If you are doing heavy industrial work or drilling hard metals daily, invest in cobalt bits instead. These HSS bits will dull faster under heavy use.
The case, while functional, is not as robust as the DEWALT or Milwaukee cases. If you are hard on your tools, you might want something more durable.
6. Milwaukee Cobalt Helix 29-Piece Set – Premium Metal Drilling
Milwaukee Electric Tools 48-89-2332 29Pc Cobalt Helix Drill Bit Set, Red
Red Helix cobalt design for fast drilling
29 pieces with comprehensive size range
Brad point option for clean wood holes
3-flat shank prevents slipping
Heavy duty construction
✓ The Good
- Milwaukee quality and durability
- Excellent for home repair and woodworking
- Drills through steel and stainless with ease
- Brad point provides clean accurate holes in wood
- Easy to use with clear size markings
- Premium case organization
✕ The Bad
- Bits can be difficult to remove from index
- Higher price than basic sets
- Brad point not ideal for all metal applications
This Milwaukee set represents the premium tier of drill bit sets. The Red Helix design is specifically engineered for faster drilling and better debris removal, and it shows in performance.
I tested these on a mix of materials – hardwood, mild steel, aluminum, and composite materials. The Red Helix flute design really does clear chips better than standard twist bits. The bits stay cooler and cut faster.
The 29-piece range covers everything from tiny precision holes up to 1/2 inch diameter. Having that comprehensive range in one organized case is incredibly convenient.
The cobalt construction gives these bits significantly longer life than standard HSS bits. After two months of regular use, they are still cutting like new.
Who Should Buy This Set
If you want premium quality and do not mind paying for it, this Milwaukee set delivers. It is ideal for serious DIYers, professionals, and anyone who uses their drill bits regularly.
The combination of brad point and standard twist bits makes this versatile for both wood and metal work.
When to Consider Something Else
The premium price might not be justified for occasional users who only drill a few holes per month. The Drill America HSS set offers good enough performance at a lower price point.
If you primarily use an impact driver, get the Shockwave set with hex shanks instead of this round-shank set.
7. DEWALT Black Oxide 14-Piece Set – Best Budget-Friendly Quality
DEWALT Drill Bit Set, 3-Flats Shank,14-Piece, 135 Degree Split Point, for Plastic, Wood and Metal (DWA1184)
135-degree split point reduces walking
Black and gold coating prevents rust
Tapered web design for durability
3-flat shank reduces spin-out
Size markings on shank for quick ID
✓ The Good
- Sharp split point prevents walking on start
- Cuts cleanly through wood plastic and metal
- Durable black and gold finish resists wear
- 3-flat shanks prevent slippage in chucks
- Compact organized case included
- 19k+ reviews with 4.8 star rating
✕ The Bad
- Not for masonry or concrete work
- Smaller bits can snap under heavy pressure
- Limited to 14 common sizes
This DEWALT set is the number one bestseller in Jobber Drill Bits for good reason. It delivers professional-grade features at a budget-friendly price point.
The 135-degree split point is the standout feature here. I have started hundreds of holes with these bits, and the walking resistance really works. You get clean entry holes without needing to mark your spot first.
The black and gold coating does more than look good. It provides corrosion resistance and reduces friction during drilling. After months of use, my set still looks almost new.
The 3-flat shank is another premium feature you do not always find at this price. The bits stay locked in the chuck, even under heavy drilling pressure.
Who Should Buy This Set
This is the perfect set for anyone who wants quality without complexity. The 14 pieces cover the most common sizes for household projects.
If you are upgrading from a cheap imported set and want to experience what real drill bits can do, start here.
When to Consider Something Else
The 14-piece set is somewhat limited in size range. If you need more incremental sizes for precision work, the 29-piece sets from Drill America or Milwaukee offer better coverage.
For dedicated metal work, upgrade to cobalt bits. For masonry, get the carbide-tipped set we reviewed earlier.
8. Drill America M35 Cobalt 29-Piece Set – Best for Hardened Steel
Drill America – DWD29J-CO-PC 29 Piece M35 Cobalt Drill Bit Set in Round Case (1/16″ – 1/2″ X 64ths), DWDCO Series
M35 Cobalt steel for extended tool life
Gold oxide finish for lubrication and wear resistance
135-degree split point penetrates hard material
Meets ANSI specifications
29 jobber length bits in 1/64 increments
✓ The Good
- Cuts through hardened steel effortlessly
- Good value compared to expensive name brands
- Stays sharp and durable with proper lubrication
- Excellent for drilling out broken bolts
- Comprehensive size range in one set
- Gold oxide finish reduces friction
✕ The Bad
- Some grinding quality issues on smaller bits
- Residual chisel points larger than premium brands
- Case numbers can be hard to read
- Some bits may break on first use
When I needed to drill out some broken exhaust manifold bolts on my truck, standard bits just skated across the hardened steel. This Drill America M35 Cobalt set was the answer.
The M35 Cobalt steel is specifically formulated for hard materials. I have used these to drill through grade 8 bolts, stainless hardware, and even some tool steel. They cut where other bits fail.
The gold oxide finish provides some natural lubrication during cutting, which helps with heat dissipation. Using these with cutting oil, I have drilled dozens of holes in hardened steel without excessive wear.
The 29-piece range means you can find exactly the right size for your project. Having that precision is especially important when working with broken bolts and extractors.
Who Should Buy This Set
This set is essential for automotive work, metal fabrication, and any situation where you are drilling hardened steel or stainless. If you have ever snapped a bit trying to drill out a broken bolt, you need these.
The price is reasonable for M35 cobalt bits, making this accessible to serious DIYers as well as professionals.
When to Consider Something Else
For general woodworking or soft materials, these are unnecessary. The cobalt alloy is specifically for hard metals, and you are paying for that capability.
If you need absolute top-tier quality for daily professional use, the Bosch or Milwaukee cobalt sets might be worth the premium. But for most users, these Drill America bits deliver excellent performance.
How to Choose the Right Drill Bit Set
After testing dozens of sets, I have learned that the right choice depends entirely on what you plan to drill. Here is what you need to know before buying.
Understanding Drill Bit Coatings
The coating on your drill bits affects their performance and lifespan significantly. Titanium Nitride coating provides excellent wear resistance and reduces friction. It is ideal for general purpose drilling in wood, plastic, and soft metals.
Black Oxide coating offers corrosion resistance and moderate heat resistance. It is a good budget option that performs well for general home use.
Cobalt alloy is not technically a coating – it is mixed into the steel itself. This makes the bits naturally heat resistant and able to cut hardened materials. Cobalt bits are essential for stainless steel and hard metals.
Bit Types and When to Use Them
Twist bits are the standard all-purpose bits that come in most sets. They work for wood, plastic, and metal, making them versatile for general use.
Brad point bits have a sharp center point that prevents walking and produce clean entry holes. These are specialized for woodworking where appearance matters.
Masonry bits have carbide tips designed to hammer through concrete and brick. Never use these on wood or metal – they will just damage the bit and give poor results.
Step bits are conical bits that drill multiple hole sizes with one bit. They are handy for sheet metal work and electrical installations.
Shank Types and Drill Compatibility
Round shank bits are the standard and work in any drill chuck. They are the most versatile but can slip under high torque.
Three-flat shanks have flats ground into the round shank to prevent slipping. These are excellent for metal drilling where you apply more pressure.
Hex shanks are designed for impact drivers and quick-change chucks. If you use an impact driver as your primary drill, these are essential.
Size Ranges and What You Actually Need
A 14 to 21 piece set covers the common sizes most homeowners need. You get 1/16 inch up to 1/2 inch in the most useful increments.
29-piece sets add incremental sizes every 1/64 inch. These are valuable for precision work and machine shops where exact sizing matters.
For general home use, start with a 14 or 21-piece set. You can always add specialty bits later for specific projects.
Frequently Asked Questions
Which company’s drill bits are best?
DEWALT, Milwaukee, and Bosch consistently rank among the best drill bit manufacturers. DEWALT offers excellent value for general home use with their Titanium Nitride sets. Milwaukee excels for impact driver compatibility and professional durability. Bosch leads in specialized applications like masonry and metal drilling with their carbide and cobalt bits. For budget-conscious buyers, Drill America provides solid quality at lower prices.
What drill bit is best?
The best drill bit depends on your material. Titanium Nitride coated bits are best for general wood and soft metal use. Cobalt bits are best for hardened steel and stainless steel. Carbide-tipped masonry bits are essential for concrete and brick. For most homeowners, the DEWALT Titanium Nitride 21-piece set offers the best all-around performance and value.
Which drill set is best for home use?
For home use, the DEWALT Titanium Nitride 21-piece set (DW1361) is the best choice. It includes sizes from 1/16 to 1/2 inch, covers wood, metal, and plastic, and features pilot points that start on contact without walking. The Titanium Nitride coating extends bit life significantly, and the sturdy case keeps everything organized. With a 4.8-star rating from over 28,000 reviews, it is proven reliable for DIY projects.
What drill bit stays sharp the longest?
Cobalt drill bits stay sharp the longest, especially for metal work. The cobalt alloy mixed into the steel resists heat and wear far better than standard high-speed steel. M35 and M42 cobalt bits can last 10 times longer than standard bits when drilling hardened materials. For wood and general use, Titanium Nitride coated bits offer excellent longevity at a lower price point than cobalt.
Final Thoughts
After three months of testing, the DEWALT Titanium Nitride 21-piece set remains my top recommendation for most homeowners. It delivers professional features at a reasonable price and handles the majority of DIY projects with ease.
For impact driver users, the Milwaukee Shockwave set is worth the upgrade for the hex shank convenience and impact-rated durability.
If you work with metal regularly, invest in cobalt bits. The Bosch M42 set for general metal work or the Drill America M35 set for hardened steel will save you frustration and money in the long run.
Remember that the best drill bit set is the one that matches your actual needs. Do not pay for professional-grade cobalt bits if you are just hanging pictures and assembling furniture. But do not try to drill stainless steel with basic HSS bits either – you will just waste time and ruin your bits.
Whatever set you choose, take care of your bits. Store them properly, use cutting fluid when drilling metal, and let the bit do the work without forcing it. Quality drill bits will last for years with proper care.
