    About products
     PDC anchor shank drill bits are mainly used for the coal seam, dam and roadway construction of bolt-mesh support. Their life are 10-30 times of tungsten carbide bits. Usually the anchor shank drill bits have 2 or 3 wings.
     Two-wing PDC anchor bits (semi-round standard type) is applied to the hardness not bigger than f<8. 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.
    About us
     LD adopt high quality PDC cutters and advanced brazing technology, so the anchor shank drill bits have high impact resistance and stable performance, can be applied to rock formation of f below 14,like gravel, granite, limestone, etc.
     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
