Step Bits with Center Punch

Good buy Works great

Nice stepper drill. I used it to enlarge a hole in a steel residential front door. It resized the whole perfectly for a new viewport. I also used it to drill a hole in an electrical box. Good durability. Good value. Speedy, on time delivery. I like.

Worked great at first, but didn't last as long as I would have liked. It started getting dull making it difficult to continue to use. At first it was nice and quick cutting through thin metal, but after a few holes it got slower and slower. There wasn't a wobble to it, so that was good. I like the size variety, but when the smaller sizes start getting dull, it's harder to use to get to the bigger sizes.

Worked fine for what I used it for. Would be better with a drill press.

Value of this set is worth it

Worked great for my home project. The case is an extra bonus. I'm happy with my purchase. :)

This bit is sharp, but is fairly soft. After drilling one hole in sheet metal, the bit has dulled quite a bit.

I needed to drill a hole in a lens board which is 3/16” aluminum. The bit drilled through easily. The hole was very clean though I cleaned up the backside with a Dremel. I was very pleased with the quality of the bit.
