If you’ve ever needed to expand the size of a hole and didn’t have the drill or drill bit to do so, get this now! Used it three times already, worth every penny. Good quality at a great price, what’s not to like.

These step drills make doing a job so mush easier especially when multiple holes are required, no need for changing drillbits as each hole size is marked on the step drill, excellent for softer metals and or other materials not for hard metals

They were very helpful, I just wish the thickest one was even thicker and not as long as the other two.

I needed to make a 3/4" hole in an electrical box and couldn't find my 3/4 hole saw so I bought these thinking that they'd be useful for other things too. Yeah, no. Getting any of them to start cutting on the steel box, even with a punch mark, was a struggle. When I did, the first one stopped cutting at all while transitioning from 3/8" to 7/16". No matter what I did it just would not drill any deeper (yes, the box was empty and deep enough) so I switched to one of the others. It too quickly dulled and refused to drill the 7/16" hole. I tried the third at that point, not expecting good results, and it too dulled, got hot, and refused to drill the 7/16" hole. No, the box is not some wild super steel, just a plain old steel waterproof electrical box. What a waste of money these were!

Idk what the negative reviews are talking about. These worked fine for me. I used them to drill holes in my Weber kettle to add thermometers. I don’t expect to drill into metal very often, so for 6 bucks, these worked great.

For the price they work I guess. What these are for is if you need to drill a couple holes and don’t want to spend money on a decent step bit.I was able to drill two holes in stainless and almost two in sheet steel before one stopped cutting in sheet steel. Went to the other narrow bit with more steps on it and was able to complete the hole, but immediately I felt like it wasn’t as sharp as the first. I never tried the big triangle one. What was weird is it cut the stainless like butter and seemed to quit on the sheet steel. Maybe the two stainless holes dulled it, but that doesn’t explain the second not really cutting the sheet steel without some effort. Also the coating wore off pretty quick.Lesson here is just because something looks like something else that doesn’t mean it is the same. For cheap step bits I still like HF and I have never owned a serious high dollar quality step bit so I can’t comment on those.3 stars for me meaning average.
