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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Husband loves it! *by C***R on April 18, 2016* This is exactly what my husband was looking for and it is a heart addition to his work room!
