Tricone bit information
Tricone bit is mainly used in drilling, exploration, petroleum and trenchless as pilot bit. 
 
According to cutting material, Tricone bit can be divided into TCI bit and Steel tooth Bit.  
 
TCI bit adopts high-strength and high-toughness hard alloy teeth, optimized design of tooth row number, tooth number, tooth exposure height, and unique alloy tooth shape, giving full play to TCI bit's high wear resistance and excellent cutting ability.
New wear-resistant material is applied to weld the tooth surface of the Steel tooth bit, which can maintain the high penetration rate of the Steel tooth bit and improve the life of the cutting tooth of the bit.
