The Grinder itself is great it fits perfectly in my 5/8inβ 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 1/8β 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 doesnβt 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.

The tool oiler leaks. The bottle that was included did not have a cap to close the tip after you snipped to use it. The case is somewhat unusable if you do not wish to unscrew the oiler from the hose. Have noe experience with this style of grinder, so am not comfortable with it (yet?). Used it to split a rusted nut and use to clean up rough areas on 3D printed parts.

Easy to use like using a pen .does a good job . Dis like was it use to much oil.

This will accept 3mm bits and tips but it DOES NOT accept my 50 or so 1/8″ bits so do not get it if you expect to use your old 1/8″ bits.

The bits that came with it fit fine, but most American made 1/8 inch bits wonβt fit. Makes the unit mostly useless.
