Mining Drill Bits

Product Introduction

The PDC (Polycrystalline Diamond Compact) Mining Drill Bits with high quality PDC cutters are used as the cutting teeth. The bits have high wear resistance, high impact resistance which can improve drilling efficiency. The bits are used in advanced welding technology, which can guarantee the bits' high welding strength, longer life and high comprehensive construction efficiency. The Mining Drill Bits is suitable for wide-range rock formations and it have high ration of finish holes with no hole shrinkage.

Features

The PDC Mining Drill Bits are the most basic part of coal mine roadway support. It combines the surrounding rock of the roadway and at the same time, self-supports the surrounding rock. It 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. And the application of PDC has greatly improved the drilling efficiency of the top bolt bit and gradually replace the tungsten carbide roof bolt bit.

Advantage

1. Adopt diamond cutting teeth for higher drilling speed and longer service life. Suitable for soft and medium hardness formations.

2. With wear-resistant inserts, PDC mining drill bits do not require polishing and are easy to operate.

3. No pore shrinkage and high porosity.

4. Years of manufacturing experience.
