BQ NQ HQ PQ Natural Geological Surface set diamond core drilling bit , rig drill bits
1. Impregnated Diamond Core Bits :The diamond particles are not only distributed on the surface of the carcass (some carcass surfaces are smooth), but also distributed inside the carcass. As the work progresses, the carcass wears and the diamond particles are continuously exposed, so the drill bit can maintain a stable rotational speed and has a wide application range.
2. Surface-Set diamond bits:Diamond particles are only distributed on the surface, and generally the particles are relatively large.
