  • Holy cow batman, this thing works great!
Style: 3-16" - 1/2"
The media could not be loaded. I don't know what it's made of, but it is hard and sharp. Goes through structural steel so much better and faster than other drill bits that are supposed to be good. I haven't tried it on stainless steel yet, but the holes it drills into structural steel are comparable to how good individual M35 bits perform on structural steel, and since those same M35 bits will go through stainless, then I'm confident this Dewalt step bit will go through stainless steel just as well. I will have an opportunity to test it on stainless steel in about a week from now and can give an update afterwards. Update: I picked up 2 other step bits, one Oxmul M35 (5% cobalt) and one Stroton (6% cobalt). The Dewalt similarly outperformed those as well. I drilled stainless steel with the Dewalt and got a surprise---it quickly accelerated in expanding/drilling out the hole once a pilot hole was created. All drilling was done with moderate even pressure at relatively slow speed. ... show more

  • Best bits I've ever used
Style: 3 PC Set
Drilled 22 1/2" holes in my Teske trailer. Still like brand new. Starts like a quality bit then zips right thru to the hole size. Went so fast with the hole I went past the 1/2" mark.

  • Drilled steel like butter
Style: 3-16" - 1/2"
Drill bit was recommended by vendor I purchased the accessory I was mounting. Used it to drill 6 holes through a heavy steel loader bucket on a tractor. The smallest step took a bit to punch through at the recommended slow speed setting, but once that tip made it through, the next steps on the bit went quick and easy with nice clean holes at the finish. I didn’t need a file to clean up any edges as I often do when drilling steel. Great drill bit. ... show more

  • Did the job for stainless
Style: 7/8" - 1-1/18"
I went through the harbor freight step bits so quick it was unreal. So I got this as a hopeful upgrade to get through stainless steel. I ran cold water on it through the entire cut, and it wasn't an easy process but eventually I got through. While the stainless steel seemed to cut the bit just as much as the bit cut the stainless, it did the job. I would buy this bit again for anything else. Stainless steel is a beast on its own. Hate that I only got one good use out of it. ... show more

  • The best step bits I have used
Style: 7/8" - 1-1/18"
These step bits stand up to constant torture and remain sharp. I have cut through 1/2" plate steel with them (though I am sure that is not advisable) and was able to make clean holes. These bits are more expensive than some, but for the quality I think they are worth it.

  • Top of the Line Bit, albeit pricey
Style: 3/16" - 7/8"
I began my project using bits from a local hardware discount store (Warrior brand) on sale for $8.99: drilled the first hole okay though I had to drill a pilot hole to get it started; then it got dull quickly and I struggled to do a couple more holes in my new fire pit ring. Watched a You Tube review of the Dewalt bits that showed it beating all other brands so I forked out the 5x cost to try it. Total "game changer"! The 3/16" starter step eliminated the pilot hole drilling other brands seem to require. This Dewalt bit cut through the steel like butter. I drilled a total of 56ea, 9/16" holes and the last hole cut just as easy as the first with no apparent dulling. Will never buy another drill bit brand; I'm completely sold. BTW, I also used an impact driver instead of your standard drill. Performed beautifully together! ... show more

  • Great kit
Style: 3 PC Set
I believe the value for money in this kit is clear as there isn't the need to purchase multiple drill bits to work with. I can't say how durable it is but considering that I've used one bit to drill over 40 holes in different metal thickness, I believe it should be able to get to 100 and still be drilling holes in metal smoothly. ... show more
