The Brush Research GB Flex-Hone in 3-1/4" (83mm) diameter features 240 grit silicon carbide abrasive globules, delivering a flexible, self-centering honing action ideal for cylinder bores, hydraulic cylinders, and engine components. Its flexible design conforms to the bore geometry to produce a smooth, consistent surface finish.
Designed for use with honing oil or coolant, this tool effectively removes burrs, improves surface texture, and creates the crosshatch pattern needed for proper oil retention and component break-in — making it a trusted choice in automotive, industrial, and MRO applications.
