114-117
Soft Formation Tooth Bits
The 114-117 bits are used to drilling 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.
