SMBits – Built for Sheet Metal. Backed by the Bad Dog Bite.

Sheet metal can be a pain—snagging, warping, walking, or leaving the backside looking like a busted can. That’s why we built the SMBits: a brand-new set of solid cobalt drill bits engineered to tackle sheet metal clean, fast, and without distortion.

Whether you’re punching a 3/8" hole in stainless steel or drilling into aluminum, brass, or even solid surface, these cobalt bits grab fast, cut smooth, and leave almost no burr. And they don’t stop at metal—you’ll use them on plastic, wood, laminate, and more. Clean cuts. No nonsense.

✅ Solid Cobalt Build – Cuts hard metal clean without burning out
✅ Quick Start Multistep Tip – Self-centers on contact and reduces backside blowout
✅ Hex Shank Drill Bits – Won’t spin in the chuck; fits impacts and drivers
✅ Lifetime Guarantee – Wreck it? Dull it? We’ll fix it or replace it. For life.

14-Piece Set Includes:
3/32", 1/8", 5/32", 3/16", 7/32", 1/4", 9/32", 5/16", 11/32", 3/8", 13/32", 7/16", 15/32", 1/2"
All with 1/4" quick-connect hex shanks, packed in a rugged metal index that’s shop-tough and toolbox-ready.

Frequently Asked Questions

Sheet Metals including Stainless Steel, Mild Steel, Aluminum, Brass plus Plastics, Wood, Laminate, and Solid Surface.

Concrete, Stone, or any other kind of masonary will dull our Sheet Metal Bits immediately. Very hard steel such as tool steel or carbide cannot be drill because they are harder than the cutting surface of the bits. Glass. If you need to drill any of these materials consider our Multi-Purpose Drill Bits.

It depends on what material you are planning on drilling through. The harder the material, the faster the edge will dull. If you use a cutting lubricant such as Bad Dog Drool, and make sure to keep the rpm and pressure low, you'll get a longer life too. But, good news! They’re Guaranteed For Life! If you dull or damage a bit send it back to our shop (24 Broadcommon rd, Bristol, RI) and we sharpen/replace it for Life!

Yes! Unlike our Multi-Purpose Drill Bits we strongly recommend using cutting oil or wax (like our Bad Dog Dried Drool) with your Sheet Metal Bits. It will speed up your drilling and keep your bits sharper, longer.

Use low speed ~ 600 RPM and light pressure. This is just about the sweet spot for most cordless drills. Each bit has a quick connect Hex End and can be used in an Impact Gun, but be aware that impact guns opperate at a much higher speed ~ 3000 RPM. When using Sheet Metal Bits in an impact gun control your speed by partially pulling or feathering the trigger. Also be sure to prevent the impact mode from kicking in by only using light pressure.

We love quick connect hex ends, they make changing bits quick and conventient in an impact gun and prevent slipping in a traditional drill ~ we wouldnt make a bit without them! But be aware that impact guns opperate at a much higher speed ~ 3000 RPM than a traditional drill. Sheet Metal Bits should be spinning much slower ~ 600 RPM. When using Sheet Metal Bits in an impact gun control your speed by partially pulling or feathering the trigger. Many modern impact guns come with an adjustable speed setting, that should always be set to the lowest setting. Also be sure to prevent the impact mode from kicking in by only using light pressure when drilling.
