How can I sharpen this cutter?
Nanograin carbide cutters are designed to be rotated to a fresh edge when one side becomes dull. Loosen the screw, rotate the cutter to a new cutting edge, and retighten securely. If all edges have been used, light sharpening can be done carefully with a fine diamond sharpening card or diamond stone and lapping fluid. Maintain the factory bevel angle and apply light pressure. Avoid overheating the cutter.
Always ensure the cutter is seated flat and tightened securely before returning the tool to service.
Safe use of carbide cutters
Avoid sharp impacts, as carbide inserts can fracture if struck. Always cut at or slightly above centre to maintain control and reduce aggressive cutting action. Wear a dust mask, safety glasses, and a face shield when turning, and keep loose clothing, hair, and gloves well clear of the work area.
Price is per cutter, in Canadian dollars.
