Brush Research GBD41212 Heavy Duty Flex Hones for Block Cylinders or Liners, 4.5

Flex-Hone Flexible Cylinder Hone, Heavy Duty, Series: GBD, 4-1/2 in Bore Diameter, 6 in Abrasive Length, 13-1/2 in Overall Length, 120 Grit, 1200 rpm Maximum, Carbide Abrasive silicon, applicable materials: mild steel, stainless steel, cast iron and other softer ferrous materials The BRM Flex-Hone tool is a strong, flexible honing tool with a smooth cutting action. Its unique construction allows the abrasive globules or "stones" to float, ensuring the tool is self-centering, self-aligning with the hole and self-compensating for wear. The tool is available in a variety of different grits and sizes ranging from 4mm to 36 inches. Whether you need to deburr cross holes, surface finishing or edge blending, there is a Flex-Hone tool designed for you. A non-directional or striped pattern is created on the surface that contains valuable valleys between the plateaus for oil retention. Finer grits can help achieve individual RA finishes. In automotive, hydraulic, pneumatic or industrial applications, the Flex-Hone tool will provide a superior surface finish resulting in higher product yield, longer product life and less product rejection.
