For steel tooth drills, the tooth surface is hard and has new wear resistance.
The material thus extends the life of the cutting structure while still maintaining a high ROP.
90 ° U-shaped Roller Bit Advantages:
Bearing with high saturated nitrile rubber reduces sealing pressure and improves sealing reliability.
G-Gauge protection improves the gauge ability and prolong the service life of the bit.
A row of teeth is added between the back taper and the outer row to dress the wellbore and protect the body of the cone.
