Review: Indestructible - 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.
Review: Great!! - I’ve never used a step bit before and I have been missing out. This thing is amazing, it drills through metal with ease and it seems to continue to stay sharp. I have used drill bits in the past that were made for metal and they got dull so quick but this step bit keeps on going. I also use oil lubricant to help keep the bit cooler which I think helps a lot. I am very happy with this product and it was well worth the money.

## Features

- 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.

*by S***E on April 30, 2026*

This is the most amazing step bit I have ever used!!! I didn't know that this existed until I watched "project farm" on YouTube. I use it to drill through high tensile strength semi truck frame. It was absolutely the best and fastest cut I have ever seen. 100% the best. If there is something better, please let me know.
