Review: Great price - Amazing for its size and price Review: Satisfied. - The Grinder itself is great it fits perfectly in my 5/8in” boring bar holder on the QCTP and at 25 psi has enough power to grind the hardened jaws of my lathe chuck. However, it says 3mm or 1/8” shank sizes on the bits. These are not the same and 1/8 may fit with some serious forcing. I put a dremel collet in it and even though they take different collets it has worked fine. The oiler doesn’t want to seal on the grinder hose and the grinding stones that come with it are badly mounted on the shafts. All in all, great tool. ## Features - 【Specification】-----1/8" Collet-----1/4" Air Inlet-----2 CFM Avg.

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 ### ⭐⭐⭐⭐⭐ Great price *by P***P on March 15, 2026* Amazing for its size and price ### ⭐⭐⭐⭐ Satisfied. *by A***R on September 12, 2016* The Grinder itself is great it fits perfectly in my 5/8in” boring bar holder on the QCTP and at 25 psi has enough power to grind the hardened jaws of my lathe chuck.
