PDC anchor bits are high-performance, small-diameter drilling tools (typically 27mm to 42mm) designed for rock bolting and roof support in coal mines and underground engineering projects. Featuring a durable 2-wing structure with 1304/1304-half PDC cutters, these bits deliver exceptional longevity and efficiency in soft to medium-hard rock formations.
PDC anchor bits are widely used in:
Coal mine roof and sidewall support
Anchor network hole drilling
Rock bolting and ground reinforcement
Tunneling and underground construction projects
