Review: Well worth the price, drilled over 300 holes in stainless and galvanized without wear! - This is surprisingly good!!! Purchased in order to drill out #9 nail holes in hurricane straps to fit #10 structural screws where added pull-out resistance is needed. I had already drilled about 80 holes in 18ga stainless steel with a well known name brand unibit that cost 3x as much. But it has stopped working, and is showing both wear and heat stress. Was able to finish the project with the TEMO unibit, in which I drilled over 300 holes with this new bit from TEMO, another 80 in 18ga stainless steel, and the rest in 16ga galvanized steel, and the bit still looks new, with no signs of damage or heat stress!
Review: Fastest Holes in Truck Frames - I install truck accessories, mainly snowplows. Over 60 installs per season. One of these bits has drilled over 200 holes in various truck frames, mostly Fords. I have not found a better, faster drill bit. Absolutely hands down the most efficient tool to cut holes in frames I've ever used. Now if I could find a locking impact rated 1/4" bit extension that performs as well as this I'd be set.

- Double spiral flutes for more efficient swarf clearance; 1/4 Inch hex Shank with quick release slot to eliminate slipping; Self-starting for clean holes in thin materials; 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.

### ⭐⭐⭐⭐⭐ Indestructible
*by J***T on May 30, 2026*

I have been looking for years for a good step bit. I finally found one. This thing is a beast. Cuts through steel, aluminum, even stainless like butter and lasts forever. Don't buy other brands, they don't last. This thing has the hex shank so it fits a drill without slipping, easy to use. Comes in a nice plasic storage case. Compatible with hand drill or drill press.
