1/4 Inch Air Die Grinder, 25,000 RPM Free Speed,1/4 Inch (6MM) and 1/8 Inch (3MM) collet,Mini and Compact Size,Polishing Tool

So far it has been working well! Has tons of power. It seems to have as much if not more capability as the snap on grinder that I use at work

I’m really impressed with this. I got it as I have a lot dremmel size fittings and they will work with the smaller collar. Overall good tool.

I took my other die grinder and put a 1/4 inch carbide burr in it . I then put the collet in vise and ran the burr through it . It works perfect now . NOW all you have to do is loosen lock nut to change tools. A 1/4 inch drill bit might work . Go slow & straight

As everyone else says, the Collet is too small. some people managed to force their bits in, I could not force it in far enough for it to run true(not wobble). If the collet from my old unit had not fit, this absolutely would have been returned, due to being unusable. Other than that, it's still working after a couple hours use.

Solid build. Excellent buy!

This is a real deal. Works well for me. I use it to sand and polish wooden bowls that I make. I gave it 4 stars for 2 reasons. Number one, it must use much more than the advertised 2.8 cfm at 90 psi. My compressor runs more than when I use air tools rated at 4.0 cfm at 90 lbs. I have a polisher that is rated 15.0 cfm at 90 lbs and the compressor doesn't run anymore than this die grinder. Number 2, as someone already stated, it is almost impossible to change attachments without removing the collet. Major nuisance. Otherwise, it has worked well for my needs.

I've used this primarily for shaping/carving woodworking projects, and it does the job. Small, light, easy on the hands, which makes it accurate for the type of work I'm doing.

Works well and would definitely buy again. The first one needed replaced because it didn't work but the second one was great
