YINHAI Tricone Bits Advantages:
YINHAI TRICONE BITS, ENGINEERED TO DRILL:
--- Since the end of 2021, our factory has added a new process for better bearing performance--bearing polishing,
We polish the bearing after finished turning, After polishing, it is very smooth like mirror, very very smooth and shining.
Extend the service life of our drill bits, allowing customers to get a better quality product for the same value.
--- YINHAI TRICONE BITS, ENGINEERED TO DRILL:
IADC 117/217/327, IADC 417/437/517/537/637 (435/535/635), Steel Milled Tooth and Chisel/ Scoop/ Conical/ Sphrical Inserts Teeth
Suitable for Water, Oil, Gas, Geothermal well drilling, Mining and HDD drilling
