26‑50mm Coal Bolting Drill Bit
Different from general drilling bits, this series of
two-wing PDC anchor bits
is professional consumables for underground coal mine support projects, specially adapted to mine-specific rock formations such as coal seam, mudstone and shale, and compatible with mainstream pneumatic and hydraulic mining drills. The widened two-wing junk slot design adapts to harsh underground working conditions with heavy dust and coal residues, effectively preventing bit balling and sticking. All standard sizes (26mm, 27mm, 28mm, 29mm, 30mm, 32mm, 40mm, 42mm, 50mm) are in stock for fast delivery. We support foreign trade OEM/ODM customization and provide stable supporting supply for global mining projects.
