Review: Good - Use it often, really like the bit.
Review: Holy cow batman, this thing works great! - 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.

## Questions & Answers

**Q: Do these work with the small 1/4 drive impacts?**
A: Yes, the DWA1790IR will work with the 1/4" Impact Driver.

**Q: Why do they advertise this as 7/8-Inch-1-1/8-Inch. Looks like it also does up to 7/8?**
A: I think the statement implies that is capable of doing an 7/8 hole for an 1/2 ko, and an 1 1/8 for a 1 inch ko. Also its a great step bit!

**Q: has anyone used these with stainless steel ? im looking at regular use with ss electrical panels and sheeting up to 1/4" thick.**
A: Yep, can be use with stainless steel like butter :)

**Q: Does these bits come in a carry case or bag**
A: No, this will not include a case or bag.

Creates a smooth, clean hole in metal with no burrs. Very sharp and quick in mild steel sheet metal. It's the best one I've used and is highly rated by PF on the tube.
