Soft Formation Tooth Bits
The 114-117 bits are used to drill low-compressive strength, soft formation. 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 bits type this hard facing
completely covers the bit teeth.
127
Medium-Hard Formation Tooth Bits
The 127 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.
