Its unique construction allows the abrasive globules or "stones" to float, ensuring the tool is self-centering, self-aligned with the bore, and self-compensating for wear. The tool is available in a variety of different grits and sizes ranging from .157 in to 36 in. Whether you need to deburr cross holes, finish surfaces, or blend edges, there is a Flex-Hone tool designed for you. A non-directional or scratched pattern is created on the surface containing 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 that brings increased product yield, longer product life and less product reject.
