The Complete Drill Bit Set for Metal: 29 Sizes, Zero Gaps
When you’re drilling into stainless steel, cast iron, or hardened alloys, the last thing you want is to reach into your toolbox and realize you don’t have the right bit size. That’s why professionals, mechanics, and serious DIYers choose a complete drill bit set for metal.
A 29-piece cobalt drill bit set gives you every size from 1/16” to 1/2” in 1/64” steps. No gaps, no compromises — just precision and performance for any job.
Why a Complete Set Matters
Most drill bit kits leave frustrating gaps between sizes. You might have 10 or 15 bits, but when you need an in-between size to tap threads, drill pilot holes, or ensure a snug bolt fit, you’re out of luck.
With a 29-piece set, every size is covered. That means you can:
Drill accurate pilot holes for threading.
Match fasteners and bolts exactly.
Avoid oversizing or weakening the metal.
Switch bits seamlessly without losing precision.
It’s not about having “extra” bits. It’s about having every bit you’ll ever need.
Built for Hard Metals
Not all drill bits are created equal. Many cheaper sets are only coated, meaning the hard layer wears off quickly. Our M35 cobalt drill bits are different:
5% cobalt through the entire body, not just coated.
Rockwell hardness 66, tested and certified by SGS.
Stay sharper, last longer, and drill stainless steel with ease.
When paired with our CUT-IT cutting paste, you reduce heat, prevent burn-out, and extend the lifespan of every bit.
The Cost-Effective Choice
Yes, the 29-piece drill bit set is an investment. But consider this:
Buying individual replacements adds up fast.
A smaller set forces compromises and risks damaging metal.
One complete set covers everything for years.
Mechanics, engineers, and contractors rely on this because it saves money in the long run.
Who Needs a Complete 29 Piece Set?
Automotive mechanics: for exhaust studs, engine bolts, and bodywork.
Fabricators: for tapping threads and drilling precision holes.
Farmers and heavy plant operators: for repairs in the field.
DIY metalworkers: for projects that demand accuracy.
If you work with metal often, this set pays for itself with the first few jobs.
Final Thoughts
A complete drill bit set for metal isn’t about having “too many” sizes. It’s about never being caught short. With 29 cobalt bits from 1/16” to 1/2”, you’ll have the precision, durability, and reliability to drill through any metal — without gaps, without stress.

Frequently Asked Questions
1. Why is a 29-piece drill bit set better than smaller kits?
Because it covers every size from 1/16” to 1/2” in 1/64” increments. No gaps means more precision and fewer mistakes.
2. Can I use these cobalt bits on stainless steel?
Yes. These are designed for hard metals like stainless steel, spring steel, and cast iron.
3. Do I need a drill press, or will a cordless drill work?
A variable-speed cordless drill works perfectly. Just keep speeds low and use cutting paste for best results.
4. What’s the main advantage of cobalt over coated drill bits?
Cobalt runs through the entire body of the bit, so it stays sharper longer and won’t wear out once the coating fades.
5. How can I make my drill bits last longer?
Always drill at slow speed, apply firm pressure, and use CUT-IT cutting paste to keep bits cool and efficient.
