Proform Electric Piston Ring Filers

Effortless Precision Ring Grinding

Proform Electric Piston Ring Filers are an easy to use solution for precisely grinding down piston rings. Each grinder base is constructed from high-quality aluminum and has provisions for mounting in a vice or directly to a workbench. Raise dowels pins on the aluminum casing help to ensure that each piston ring always sits square for the most accurate measurements possible.

The included AC adapter guarantee that you have constant power to the grinder and can focus on setting the correct ring gap instead of operating the machine itself.
