## 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.

This is exactly what my husband was looking for and it is a heart addition to his work room! His job requires him to have his own tools and this was one he desperately needed. It works just like it should and he is very pleased with it so far! He needs this almost daily and he has had it for over a month without any issues with it.
