## 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**
