1. Our drill bit adopt the new type material--- superhard PDC cutters as its main cutting tool, so the service life of drilling is 10~30 times longer than the cemented carbide bits under the same rock formation; 2. Has high wear resistance and high impact resistance toughness, which reduces the labor intensity; 3. Non-diameter reduction and high successful hole rate, which greatly improves drilling effiency in soft and medium-hard rock formation; 4. PDC is not easy to be collapsed ensured perfect stability in penetration and hole drilling; 5. All of our roof bolting bits could be made to the inner spiral; 6.Wide range of application from 5≤f≤12.
