South of the capital170 km, 110 km to Tianjin, North China Pearl Baiyangdian 35 km, excellent location and convenient transportation, a favorable convenient conditions for our development.We mainly specializes in Tricone Bits. TCI Rock Bits,Steel Tooth Tricone Bits,PDC Bits, PDC Drag Bits, PDC Core Bits, Single Bits, Bits Cones for oil,water and mining drilling.The material all tungsten carbide or high carbon steel, And the quality in accord with API and ISO standards.
TCI tricone bits for Mining and Rock Drilling
The strength and wear resistance of inserts are improve by using carbide inserts with high strength
The strength and wear resistance of inserts are improve by using carbide inserts with high strength
Surface of the high precision bearing heat treated by using advanced heat treatment process to improve the load capacity and service life of the bearing.
The service life of the bearing is further extended by adopting harder and mort wear resistant material for thrust bearing.
Preventing reflux structure has dual function, it can avoid air counterflow and dust entering into bearing when the air-compressor stop working accidentally, and separate air and water in order to avoid water entering into bearing when it works normally to prolong the life of bearing.
