The Details of Roller Bit
The Advantage of Roller Bit
The cone units of Great Roller Cone Cutters are replaceable and each main body of the Hole Openers can be used many times, thus saving the cost for the customer.
The strength and wear resistance of inserts is improved by using carbide inserts with high strength and high wear resistance.
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.
The application of engineering plate holder makes the construction more convenient and quick.
