Diamond tip drill bit, also known as PCD roof drill bit, PCD dust hog bit. Using high quality PDC cutter as cutting tooth, the drill bit has high wear resistance, high impact resistance and high drilling efficiency; the drill bit adopts advanced welding technology to ensure the drill bit. High welding strength, long service life and high comprehensive construction efficiency. It is suitable for large-scale rock formations with high precision of hole processing and non-porous shrinkage.


1. PDC diamond tip drill bit is the most basic part of coal mine roadway support. It combines the surrounding rock of the roadway and self-supports the surrounding rock.

2. diamond tip drill bit is a drill for fixing coal mine bolts. PDC (Polycrystalline Diamond Compact) is used as the cutting teeth on the two wings of the PDC roof bolt drill bit.

3. The application of PDC has greatly improved the drilling efficiency of the top bolt bit and gradually replaced the tungsten carbide roof bolt bit.


Using high-quality PDC cutters and advanced brazing technology, the anchor drill bit has high impact resistance and stability and can be applied to rock formations below 14 F, such as sandstone, limestone, marble, granite, quartz, basalt, etc. It is used for anchor net support in coal mines, dams and roadway construction.
