Teeth of steel tooth bits

1、Summarize

Teeth of steel tooth bits are made from the bit cones by milling. Most teeth are wedge-shaped. Tungsten carbide particle hardfacing is liberally applied to the working face and back cone of the teeth.

2、Structural features

Steel tooth bit is a tri-cone rock bit with roller bearing for oil well drilling. Tungsten carbide particle hardfacing is liberally applied to the teeth surface. The bearing system is suitable for high rotary speed. It can perform high PRM, long working life and reliable drilling in appropriate formations. It can be adaptable from soft to middle medium formations, widely used in oil-well drilling, mining, geological prospecting, hydrogeologic prospecting, piling, geothermal exploitation, water-well drilling etc.

Apply high abrasion resistant alloy sand on the face of palm and teeth to ensure the long working life.

Optimized teeth placement, height and shapes guarantees the well capacity of cutting and excellent cutting speed.

3、Recommended drilling parameters

Note: The upper limits of drilling weight and rotary speed recommended in above table could not be used at the same time.
