About PDC:
Polycrystalline Diamond is a diamond complex produced by diamond sintered with bond under high temperature and high pressure. It has very high wear ability and high thermal stability. It’s the ideal material for mining and geological drilling bits, while the PDC drillbits have high drilling efficiency and longer life.
Characteristics:
Type: 2 wings PDC roof bolt bit
Size: φ25-φ42(mm)
Application: It is suitable for different rocks, applicable rock formation: f≤12. The drill is of a long lifespan and stable performance. The drilling efficiency of medium hard rock (sand rock) could be greatly improved.
XI’AN J.W. ROOF BOLT DRILL BITSdivided into 2 kinds, one kind is double wings roof bolt bits, and the other kind is triple wings. All suitable for drilling the anchor-network support holes in the coal mine. No sinkhole and high successful hole rate. It could greatly improve the drilling efficiency for the medium-hard (i.e. sand rock).
