The taper mill hardfacing is designed to clean the casing without cutting it, and to penetrate very gradually. The upper part of the taper mill is long enough to allow the addition of stabilizing blades while still remaining easy to fish. DRILLSTAR Taper mill is available in two types, long or short. Blades, whether spiralled or straight, are fully customizable.
