Factory Direct: 12.25 API Standard Tricone Bit for Water Well Rock Drilling

Milled tooth Tricone Rock Drill Bits: The milled 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.
