The main structure features:
Steel tooth bit is tri-cone bit with roller bearing for oil well drilling. The tooth surface is welded and applied with tungsten carbide powder coat. The bearing system is suitable for high rotary rate.Drilling in the adaptable rock formation. The bit can obtain high PRM,long working life,reliable working.
STEEL TOOTH BIT114-117
Soft formation tooth bits
The 114-117 bits are used to drill low-compressive strength,soft formations. Long projection tooth length 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 cover the bit teeth.
127
Medium-hard formation tooth bits
The 127 bits are used to drilling 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.
317
The 317 bits are used to drill hard and abrasive formation.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 formation with a crushing, cutting action.
