Grind your piston ring end gaps quickly, easily, and accurately. Don't risk damaging an expensive set of rings by doing this job with a hand file. Simply hold one end of the ring against the abrasive wheel and turn the crank.
Guide pins help maintain proper alignment for a straight cut. Cutouts in the base let you clamp it temporarily to your workbench; bolt holes also allow permanent installation. Includes one abrasive blade.
The Piston Ring Filer Replacement Abrasive Disc is also available (Part No. 3136-102).
