Good product
Have not used the ring filer yet but it appears to be very well made and it should work very well also. I filed some used rings as practice. Should have had one years ago.

Great little tool
Worked great. Was able to gap my 5.3l rings for turbo application. Took some time to get the first couple done while learning the tool but breezed through the rest with no problem.

Proform ringfiler
It gets the job done, very easily and with a good result I hope! Its just that I use it for filing rings, which happens very rarely! I guess I need to rebuild another engine😀

Piston ring filer
The Proform 66785 piston ring filer was well worth the investment,I bought it for use on power sports engines,it works perfect for filing ring end gap clearance on engines. I recommend buying one if your going to do a lot of engine rebuilds.

Works Great
I used this last night and it took me an hour and a half to do 16 rings that had zero gap and had to go to .018" and .020" It takes off about .001" per revolution. You have to sneak up on it because once you grind it away, you cant put it back. Very easy to use, I screwed it down to a block of wood for stability. Would buy one again if I needed it.
