The Flex-Hone Tool is a resilient, flexible honing tool with globules of raw grain abrasive in a resin bond. The Flex Hone Tool will produce a controlled surface finish depending on the grit and abrasive type used. The Flex Hone is also excellent for deburring cross-holes and producing an edge break. The Flex Hone has a wide variety of applications in the automotive and industrial fields.

The Flex Hone Tool is available in Silicon Carbide, Aluminum Oxide, Zirconia Alumina, Boron Carbide, Tungsten Carbide, and Levigated Alumina. Grain sizes of 20 grit to 800 grit are available in most abrasive types. The Flex Hone Tool is available in diameters from 4mm (.157") to 914mm (36").
