Complete Junk
Size: 0.5 inches
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! ... show more

sorry to say, I am a bit disappointed in the drill I tried using.. could not penetrate a 2" square thin wall mild . steel fence post I was surprised and had to use regular drill bit. I am sure it will be fine for aluminum or wood. (the price was low so maybe I should have been more aware of any potential shortcomings. ) ... show more

Good Set of Step Drill Bits
Size: 0.5 inches
Step drill cone bits were ordered to increase drill holes without splitting or damaging holes in wooden crafts I make. I made a bell ringer stand without screws, nails or glue and needed to slightly increase drilled holes for dowel wedge. Attached photos show before in raw wood and after black staining. Step drill cone bit works faster than my hand rasp filing in holes. ... show more

A swing and a miss.
Size: 0.5 inches
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. ... show more
