Product description

Bits sizes range from 3 7/8” to 26”.and cover almost all IADC codes.It can be used in various of 

different fields,mining,hydrology,subterranean heat pilling,water well drilling and oil well drilling.This type of bits have 

optimal bearing design, it can be working stably in high WOB,and the quality tungsten carbide inserts oncone and the gauge make a good wear resistance largely extend the working life of bits.It is suitable for medium to hard formation
