Product Description

A resilient, flexible, honing tool with a soft cutting action. The abrasive (points) globules each have independent suspension that assures the Flex-Hone® to be self-centering, self aligning to the bore, and selfcompensating for wear. Creates the required cross hatch for piston ring seating.
