Products feature
Our Mining Anchor Drill Bits are specifically designed for drilling rock bolt holes in coal mines, metal mines, and tunneling projects. Featuring top-grade tungsten carbide tips and high-strength forged steel bodies, these bits deliver superior rock penetration rates, high wear resistance, and minimal head breakage even in hard and fractured strata.
They are engineered to drill the exact diameter holes required for the safe and rapid installation of split set stabilizers, resin capsules, and threadbar rock bolts.
Key Advantages
Extreme Wear Resistance
High-density tungsten carbide inserts ensure maximum cutting life and reduced bit changing frequency.
Precision Forged Steel Body
Heat-treated alloy steel absorbs extreme impact without cracking or bending during pneumatic or hydraulic drilling.

Optimized Flushing Holes
Excellent debris evacuation design prevents bit jamming and accelerates drilling speed.

Tight Dimensional Tolerance
Guarantees perfect hole straightness and roundness, ensuring the best anchoring performance for subsequent
