Diamond files and sheets are used when conventional files fail due to the hardness of the workpiece material. Diamond files and sheets are also used for processing hardened steel. Using these products does not generate much heat, which prevents chemical wear. This allows for a longer service life for the high hardness diamond grain. Diamond needle files can be used universally in tool making.
