BLACK COATED TUNGSTEN CARBIDE CUTTER NE HP S277-014
Black coated tungsten carbide cutters are up to three times harder than conventional tungsten carbide cutters, with a hardness of approximately 3300 Vickers compared to 1600 with conventional cutters. They can be used at slower speeds without overheating, which reduces damage to the burs and guarantees a longer service life. The black coating is softer than the conventional coating, reduces clogging and ensures that cutters do not have to be cleaned as often.
Produces smooth surfaces on non-precious metal alloy.
