Re-sharpening extends the life of the Insert and saves money. The Inserts that show a decline in surface finish (a sign of wear), can have their life extended through a re- sharpening process. The Inserts are designed to allow two to three re-sharpenings, more if tolerances allow. A Sharpening Stem is available for mounting and supporting of an Insert during re-sharpening. The Stem’s hexagon shank facilitates the re-sharpening process. Sharpening must be properly performed using an appropriate grinder and grinding wheel. The original cutting angle must be maintained. Stripping and Re-coating of the Insert is required after sharpening.
