## Questions & Answers

**Q: Do you have to also buy an adapter for these to fit the drill ?**
A: No, they will fit any standard drill.

**Q: Where is it made?**
A: Do not know.  My guess is NOT the USA, but don’t know. I will say they work as advertised , and are a good value wherever they are made.

**Q: Why does the description keep referencing it's used in Wood when Cobalt bits are generally intended for drilling through hard metals?**
A: This is like the square is a rectangle but rectangle isn’t a square. The standard bits are not hard enough to drill through hard metals. When you get to cobalt, the m42 are the purely hard metal bits and can be brittle compared to the others.

These are m35 which is a bit softer than m42 and allow you to use these on metal and wood (since wood can put different type of stress on the bits).

**Q: Can the do masonry**
A: No, masonry bits look very different at the tip.
