HAOJIANG Milled tooth Tri-cone Rock Drill Bits:
The mill tooth (steel tooth) tricone bits drilling for soft to medium rock formation.
The soft formation milled tooth tricone bits are used to drill low compressive strength, soft formation. Long projection tooth
lengths are used on high offset cones to provide the greatest penetrations rates possible. Wear resistance hard facing is used to
control tooth wear. On the softest bit types this hard facing completely covers the bit teeth.
The medium formation milled tooth tricone bits are used to drill high compressive strength, medium rock formation. Shoot
projection teeth with reduced crest length are used in this series of bit designs. Durable hard facing is applied to reduce tooth
wear.
