## Questions & Answers

**Q: Are the printed measurements imperial or metric ?**
A: Imperial which was not my preference but who cares when they are super sharp and stay that way.

**Q: Are drill bits in the case or in a temporary packaging?**
A: Not sure because mine are sitting in a case belonging to a previous set, so I suspect they must have been in temporary packaging. They work brilliantly, best I have used and I have tried a lot of alternatives.
