The Brush Research BRMBC8MM Flex-Hone is an 8mm (.315") bore finishing tool featuring 180-grit silicon carbide abrasive globules, designed to produce a precise, controlled surface finish in cylinders, bores, and hydraulic components. Its flexible construction allows the tool to self-center and conform to the bore for consistent, uniform honing action.
Ideal for use in automotive, industrial, and MRO applications, this Flex-Hone improves surface finish, removes burrs, and creates the optimal crosshatch pattern required for proper oil retention and ring seating in engine cylinders and hydraulic bores.
