About Us
We are a professional manufacturer specialized in series of drill tools: PDC, PDC drill bits, diamond drill bits, etc. We can also produce other products according to the customers requirements. We sincerely welcome our friend both home and abroad to come for business talks.
About Products
Two-wing PDC anchor bits (semi-round standard type) is applied to the hardness not bigger than f8. The working life is 10-30 times of the ordinary alloy bits, and the efficiency could be improved by 60%. Besides, the PDC bits don't requires figuring, which lows the labour intensity and helps to saves cost.

Our products advantage
A. Selected higher quality diamond powder, improved the sintering technique, enhanced the bond combination strength between diamond grain
B.Improved the inner structure of the sintered cavity, the pressure and temperature become more balance, which ensure the cutter has more stable performance
C.Adopted a new type of carbide, which improved the weld strength
D.Optimized the designation of joint face, which reduced the residual stress
