BW 114 - 116
Soft Formation Tooth Bits
The BW 114-116 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.
BW 215
Medium-Hard Formation Tooth Bits
The BW 215 is 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.
BW 314 - 315
Hard Formation Tooth Bits
The BW 314-315 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.
