ABSTRACT:
A process for treating cutting tools to extend the useful duty cycles of the tools by immersing the tools to be treated in a bath of a solvent in sufficient amounts and at a temperature to remove contamination from the surface of the tools and to coat the tool surfaces with perfluoroethylene. The solvent and perfluoroethylene resin are circulated throughout the immersed tools for a time sufficient to coat the surfaces with polyfluoroethylene resin.
