STEEL/MILL TOOTH TRICONE/ROLLER CONE BITS

Soft Formation Steel Tooth Bits are used to drill low-compressive strength, soft formations. Long projection tooth lengths are used on high offset cones to provide the greatest penetration rates possible. Wear-resistant hard facing is used to control tooth wear. On the softest bit types this hard facing completely covers the bit teeth.

Medium-Hard Formation Steel Tooth Bits are used to drill high-compressive strength,medium-hard formations. Short projection teeth with reduced crest length are used in this series of bit designs. Durable hard facing is applied to reduce tooth wear.

Hard Formation Steel Tooth Bits are used to drill hard and abrasive formations. Very short, closely spaced teeth with minimum amounts of hard facing are used for breakage resistance. These bits must withstand high loads and drill abrasive formations with a crushing, cutting action.
