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.
