Steel tooth tricone bit

For soft to medium formation drilling

Reliable bearing system

All surface and teeth are hard enhaced

 

114-117, 127
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.
