Piston Ring Cutting Wheel Filing Tool, Piston Ring Grinder, Piston Ring Clearance Adjustment Tool, Manual Piston Ring Filer with 120 Grit Carbide Grinding Wheel Replace# 66785 66786

I had to grind some rings for a marine V8. This allowed me to adjust the gap easily. Count the turn of turns to get the same result every time.

Cheaply made but it works. I think it’s better than grinding the rings on a big belt sander because you have a more control of how much you are grinding off.

The handle is junk, the screw that holds the handle in is junk. Now, the disc wobbles like others have stated, but it’s not terrible and it didn’t effect me in any negative way. By the time I was on the third set of rings, I was able to count the rotations needed to get me close to where I needed and it stayed consistent. The worst part about this tool is the handle for me.

Works great

Didn’t need after all dut ready for next time

Meh. Works but doesn't last.

Just what I needed to complete the rebuild on my ATV.

For being cheap it’s alright. The wheels aren’t sterdy so they will wobble causing an uneven cut. Even cuts can be done but you have to be careful and adjust to cut where you wanted. Better off spending the extra 20 on a good one

bent handle and slop in the shaft , not worth that price
