Roof drill bit is the most basic part of roadway support in coal mine and Engineering construction.
PDC is a new-fashioned superhard compact material. It not only has the feature of wear-resisting of polycrystalline diamond, but also has the advantage of lash-resisting, high-elasticity ofalloy. Anchor rod bit made by PDC has the characteristic of long-longevity, high-efficiency, long-adaptability.

4.Feature
Compared with tungsten carbide, PDC roof drill bit has the following advantages:
The usage of PDC roof drill bit lessens the work strength. Due to the longevity, workers working underground no longer need to shoulder huge quantities of tungsten carbide roof drill bit, they only need to bring two 80g PDC roof drill bits, in the meanwhile they don't need to take the trouble to change the roof drill bits and go up oftenly to enshrine the roof drill bits.
