Too dull to drill anything.
The tips on these are pretty well completely dull. They won't make a dent in mild steel. Maybe on copper or aluminum they would work, but I have my doubts. There just isn't any bite to the tip. I have a 4 year old Dewalt step bit that has drilled hundreds of holes until the tip finally broke on it. I picked these up to finish a job and ended up having to drill a pilot hole with a Dewalt bit in order to get these to bite. The other flutes are equally dull, needing much more effort to push the bit...

5/10 Step bit
I bought this set to drill some holes in thin metal. Here is my experience. I first used the #1 bit. I tried to drill without using a center punch. It walked a lot. I used the center punch and nothing changed. The bit would actually walk out of the whole. I ended up having to use an actual drill bit to make a bigger indent so the step bit would not walk. The step bit took longer to drill than a wore about drill bit I've had for the last 5 years. I used the #4 drill bit and it was the same story....

And just as the package states, it drilled through that metal 2X faster than anything! Without this purchase, I would have used several drill bits ever increasing in size until I reached the desired hole diameter! That, my friend would have taken all afternoon and would have left me with very sore wrists and for...

Same quality as Harbor Freight
I bought this Pack hoping it would do a better job than the harbor freight step bits. To my surprise they performed the exact same. Quite a disappointment for the cost. Save yourself a pretty penny and go to Harbor freight for these.

Buy this pack, not individual bits
When bought separate, these are well over 100$, but this combo pack is the best bag for your buck. Sharp bits that grab the metal

I should have bought these years ago
Made drilling through aluminium a breeze. I was just being cheap my whole life and didn't think I needed these. I do with I had something to put them in to keep them from banging about.
Excellent bits
Gets the job done! Goes through metal like it was butter. Very pleased with these bits.

If you’re a handyman kind of guy. Buy a set
Use them for many projects. Got in a pinch and burnt up 3 bits but get the steel up.
