27mm 28mm 32mm Chisel Drill Bit For Geological Exploration

27mm 28mm 32mm pdc anchor drill bits two wings coal mine drill bit

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.

PDC Anchor Bit/PDC/PCD Roof Bit/Coal Mining Bit

PDC anchor shank drill bit is made by with premium PDC cutter, with high abrasion resistance, impact resistance and drilling efficiency. Its life is 10-30 times of alloy bit,could be applied to rock formation f≤14, like conglomerate, granite, limestone, etc.

Application:

To be used for the bolt-mesh support for the coal mine, dam and roadway construction etc.
