steel or matrix coal mining drill bits /pdc drill
ABOUT PRODUCTS
Steel / matrixPDC bit is made from PDC cutter brazed to Steel Body. The PDC cutter has high hardness, abrasion resistance and toughness, provides a cutting structure for the rock formations that respond well to failure by shearing and wears by micro-chipping, the bit life is 20-40 times, the drilling efficiency is 50% higher of tungsten carbide bit.
About us
LD offers various diamond reaming shells, they are T.C reaming shells and surface set diamond reaming shells. Liuding PDC anchor shank drill bit select top grade PDC cutter, the bit has stable performance and impact resistance, could be applied to rock formation f≤12, like conglomerate, granite, limestone
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
