Diamond files for highest cutting capacity and long tool life. 

Diamond files are used for machining hardened steels and unhardened steels or unhardened high-alloy steels; rough and fully-sintered carbides, ferrite, carbon, graphics, FRP, ceramics, hard plastics glass etc.,

Best results are obtained by using these files with light contact pressure. The protrusion and uniformly high concentration of the diamond grit on the file surface ensures smooth, free-cutting action and high depth of cut. Increased cutting pressure is not recommended, and should be avoided as it does not result in higher rate of material removal. The file can be cleaned with a soft toothbrush after use.
