Reinforced Two-Blade Roof Bolt PDC Bit

Our reinforced two-blade roof bolt PDC bit is upgraded for harsh underground mining conditions. Equipped with premium 1305 and 1308 PDC cutters , this anchor drill bit delivers outstanding impact resistance and abrasion resistance when drilling in fractured coal seams and medium-hard rock.

Compared with standard anchor bits, the reinforced structural design strengthens the cutter base to prevent tooth loss and breakage. With powerful rock-breaking capacity, it achieves stable drilling and faster footage. Widely used for coal mine bolt holes, gas drainage holes, drainage boreholes and roadway support drilling.

Streamlined two-blade concave design guarantees smooth slag discharge and effectively avoids bit sticking. As a professional PDC drill bit manufacturer, we support size and thread customization. Our mining anchor bits are exported to mining regions across Southeast Asia, Africa, South America and Oceania, trusted by coal mines and engineering contractors worldwide.
