 tri-cone drill bit is mainly used in large open-bit mining operations, such as open-pit coal mines, copper mines, molybdenum mines, iron ore mines and other non-ferrous metal mines.They are designed for the toughest and most severe rotary blast-hole applications, yet suitable for all your drilling needs.

Our bits offering includes a wide range of bit diameters with various carbide shapes/cutting face arrangements to maximize rate of penetration.Our tri-cone bits are with a proven reputation of high performance and low cost.

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.
