I was able to make a one inch hole into this sheet metal panel to run electrical conduit. What a breeze with this drill bit.

I needed to enlarge a 0.75 hole to 0.875, but the catch was that it was cutting thru 0.75 thick mild steel on a backhoe. I really thought this bit would just snap.. but it powered thru the task with ease. Two holes completed and just as sharp as new. Thank you, Vevor!

This is by far the toughest, most durable and best step drill bit I have ever tried. I’m sold. Nothing but these from now on. … AWESOME!
