Coal Mine Two‑Wing Anchor PDC Bit

This series of two‑wing anchor PDC bits is specially developed for bolt support drilling in underground coal mine roadways. It serves as an essential drilling tool for tunneling and support in coal‑rock roadway and rock roadway. Built with high‑strength carbide matrix and wear‑resistant PDC cutters, the symmetric two‑wing cutting structure delivers smooth cuttings removal and low drilling resistance. Compatible with various coal‑mine bolting rigs, these bits are used for fast hole making for anchor bolt and anchor cable holes. Widely deployed for roof and side wall anchoring drilling in underground coal mines, they handle drilling tasks in coal seam, shale, sandy mudstone and other medium‑soft to medium‑hard rock formations.
