Good To Know

Q: Can I use this filer grinder on chrome-faced piston rings? A: Yes, the 120-grit wheels are suitable for chrome, cast iron, and steel rings, but avoid excessive pressure to maintain a square edge.

Q: Does this unit replace the manual handle on the Proform 66765? A: It is an electric grinding attachment that bolts onto the Proform 66765 frame, replacing the hand crank so you can file rings faster and with less effort.
