Pdc anchor shank drill bits are mainly used to drill the roof and side supporting hole, the gas drainage, water infusion, geological exploration hole and grouting hole and so on for the coal mine seam, water conservancy and hydropower, dam and roadway construction of bolt-mesh support. The life of these bits is 10-30 times of alloy bits.
