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.
