PDC Roof Bolt Bits
Type: PDC roof bolt drill bit
Size: φ25-φ42mm
Application:
It is mainly applied to drill the Anchor-network support hole in the coal mine. The fast and high efficient tunneling is guaranteed. Based on the rock level, we could supply different types as per as customers' specify needs, such as common type, forced type, super forced type, half piece type, full piece type, double wings. Triple wings, and inner spiral.
Characteristics:
The drilling efficiency of the medium-hard rock (i.e sand rock) could be greatly improved. The PDC cutting wings have higher wear resistance and strong resistance. No sinkhole and high successful hole rate. The consumption of rolled up powder and anchor could be greatly reduced. Construction efficiency will therefore be promoted and labor intensity reduced.
And the drill rate for hard formation of the triple wings is over two times than the double wings. All of our roof bolt bits could be made to the inner spiral.
Applicable rock formation:
It is applicable for different rocks. Applicable rock formation: f≤12
