DO NOT BUY, This Is Pure Garbage!
Vortex✓ Verified Purchase•August 8, 2018
I saw the negative reviews but had some time to spare and it was many times cheaper than at Lowe's. However, it made it through only ONE hole of light material before losing its edge and refusing to cut any further holes. I have many cheap drill bits that fly through this material with no problem they just were not large enough. I though I could save money getting this multi size cutter but was wrong. I am not an expert but not a novice either the 2nd and 3rd bits met the same fate just as quick even with the addition of cutting fluid. This is JUNK so listen to everyone who says so and not the people giving it 5 stars (Either cutting balsa wood or received free for review is my guess). Or be like me, buy it, hate it, and write a 1 star review to drive the rating down to where it should already be.
... step drills are well made and come in a nice aluminum storage case

These step drills are well made and come in a nice aluminum storage case. I used one of the step drill to enlarge holes in a piece of 15 gauge galvanized angle that I use to hold my screwdrivers. The step bit bored through this metal very quickly with absolutely no problems. The bored hole was perfectly round with only slight burrs on the outlet side of the hole (expected). I would recommend.
Useful and high quality.

I bought these to drill a 5/8 inch hole for the hitch pin in my trailer receiver tube because the existing hole kept the ball too far from the hitch to allow my safety chains to attach. I used plenty of oil and was able to easily drill 2 holes through the 1/8 inch steel of the tube. The drill bit that I used did not seem to be dulled and upon inspection appeared to be as good as new when I was done. I don't know why I never bought a set of these before--I would have used them if I had them.
Nope.

To be avoided. shiny step- drill shaped object in a nice case. Believe me and all the other naysayers out there. Just like everybody else, I said "these idiots just don't know how to use a drill properly." While that may be the case, these bits do not even really have a defined cutting edge, just by a glance you could tell there is no way any cutting could take place . I used them in a drill press with a coolant mister, pilot hole to get me within 2 steps of where i wanted to end up, and proper speeds and feeds. I know there must be some money to be made defrauding people with the hopes that they will not return the item, but with amazon I don't have to put up with that mess. Ended up getting the Milwaukee bit, and while Milwaukee is hardly the king of tooling, it did what I needed and is ready for the next job.

They're not the bee's knees of step bits, but you won't beat them for the price. If you're a residential electrician who has to make the occasional modification to a box and you have no step bits... these are more than enough. If you're a commercial electrician who debates sending a particular common used metal box to a metal fab, in bulk, for a common punch out modification but wonders if a step bit will get you by, you 'might' want to try these, but one of those seemingly expensive sets might be more in order for remedying an issue in the field. Though, if you're the latter and successful, you're not gonna quible over price, are ya?
