Manual Piston Ring Filer includes 120 Grit Carbide Grinding Wheel Replace 66785 66786

Was not expecting such a great tool, description was accurate, and quality is good for the price, came with extra wheel. Had to grind my rings just a bit. Only would recommend mounting the unit on to a worktable, it was a little difficult to hold the tool down and compress the ring to the wheel and keep it flat. but the tool did what it is supposed to do. I did not feel any burs though a light file will take care of any burs. Need to go slow because it will remove material for just standard rings. Great price for the tool.

Ok. So I wanted to file some rings in my engine and saw this, got it and made a small modification, and with a drill it files fast, take your time and go slow with a drill or your going to have some big gaps, I went .030 on my rings. I wanted .028. Opps. No big deal

It get the job done. The quality is average at best but it's affordable and good for at least 8 sets of piston rings no problem.

Works as advertised

Worked great

Decent, pads are a bit out of round so rings may get a bit uneven.

Really good for the price easy to use.

As described, it works well. No real complaints.
