4 1/8" (105mm) Flex-Hone Cylinder Hone 320 grit silicon carbide
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.
