## Questions & Answers

**Q: What direction does the bit turn when looking from the air supply side to the bit?**
A: Turns clockwise or right

**Q: what size clamp goes on the air inlet hose?**
A: These are junk! They will not accept an 1/8" tool as advertised.

**Q: 1/8" Collet?  yes this is not 1/8" it's undersized. Has anyone tried finding a replacement 1/8" collet that works and fits inside? if so what one?**
A: OP is correct that it will NOT accept a 1/8" diameter bit.
5 minute simple fix, run a 1/8" drill bit through it followed by a reamer. Working fine.
I would agree that this isn't something that you should have to do but remember, it is made in CHINA.

**Q: Can it take a 1/4” collet?**
A: I don’t think so. And it probably doesn’t have enough torque to work with a 1/4” shafted tool. Just my two cents. Great little air die though, for the price.
