Tungsten Carbide Tips Coal Mining Bit Double Wing PDC Rock Drill
Bit of High Strength
According to different purposes, drill bits are classified into
cemented carbide bolting drill bits and PDC bolting drill bits
applied to coal mining and laneway and tunnel supporting grid, PDC
solid drill bits applied to coalfield geological condition and gas
drainage, water injection and drainage down coal mines, and PDC
non-solid drill bits applied to coalfield and geological
exploration.
