M35 cobalt HSS to cut stainless steel. The step drill bit is made with M35 cobalt. It is ideal for variety of materials from stainless steel, metal, plastic, fiberglass to wood. They also help to enlarge existing holes. M35 HSSCo is a high speed steel alloy made up of 5% cobalt. M35 is similar to M2, but with 5% cobalt added. The addition of cobalt increases heat resistance. It is widely used in metal manufacturing because of its ability to resist wear over conventional high speed steels, allowing for shorter cycle times in production environments due to higher cutting speeds or from the increase in time between tool changes. M35 is also less prone to chipping when used for interrupted cuts.

Very impressive, this is a reliable drill

This drill is very impressive and I have to say it cuts faster than my original pre-Irwin Unibit models. Those early Unibits were great and very durable, but the new ones aren't as good. I wanted one with a smaller 1/8" pitch and the low cobalt content of this Temo caught my eye. It is well machined and well sharpened, spins properly and actually goes through thin stainless steel in a hand drill with ease. I have one Used a full drill to drill 13 1/2" holes in stainless steel fasteners and the…

Pros

This Temo Step workout is AWESOME!

My buddy told me about a cheap step drill he bought that took him half an hour to drill through his stainless steel sink as it dulled almost instantly from one step to the next. I did a little research on YouTube. and found this Temo drill came 2nd place behind the more expensive Dewalt which is made in the same 2 helix configuration as the Temo with only one difference, the Dewalt was gold plated. I ordered Temo online and received it from Revain the next day, free shipping! I drilled a 3/16…

Drill bit 18 gauge stainless steel like butter

I bought these after reading a lot about how step drills work. Turns out most cheap ones won't drill through stainless steel. The basic principle is obvious: in order to drill through any material, the drill must be made of a harder material. For this reason, diamonds are often used for cutting. It's the hardest material there is. For step drills (and other metal drills), cobalt is the best material. However, the cheap ones don't last long as they either don't contain cobalt or are only coated…

Pros
  • Metalworking and general purpose drill bit
Cons
  • Cord is shorter than other picks
