 Engineering bits are mounted on vertical well rig,construction drilling machine or excavator and used for mining,military industry,bridge and port construction,geological prospecting,hydraulic engineering and tunnel excavation. Because of high mechanization,high penetration rate,good drilling quality,low labor intensity as well as safe operation,the engineering bit is a primary product used for modern doundation construction. 

 Engineering bit consists of cone,bearing ,shaft,cap and sealing components.The bit cone rotate round the shaft and fis mounted on a saddle to form a drilling unit.

 A special sealing system and a piston balanced structure filled with special lubricant are utilized to prevent construction bit bearing from permeation of sand,so as to improve the reliability of bearing system and prolong the lifetime of construction bit.
