Maximize your drilling productivity with the HC40 T38 D38 390 shank adapter. Engineered for the HC40 series hydraulic drifters, this 390mm striking bar features a robust T38 thread and a 38mm diameter. It is designed to handle high-frequency impacts and provide superior torque transmission for efficient drifting and tunneling in hard rock conditions.
Key Advantages of the HC40 T38 D38 390
Precision T38 Threading: The T38 connection offers a larger contact surface compared to R-series threads, allowing for higher torque transmission and easier uncoupling after high-pressure drilling.
Heavy-Duty D38 Body: The 38mm diameter provides the ideal structural integrity for medium-hole drilling, offering high resistance to bending and axial stresses during deep hole penetration.
Premium Fatigue Resistance: Our shanks undergo an advanced carburizing process to create a tough, shock-absorbing core and an ultra-hard exterior, significantly extending the service life in abrasive rock environments.
Primary Applications
The HC40 T38 D38 390 is the preferred choice for:
Underground Drifting: Reliable and fast development of tunnel faces.
Production Mining: Consistent performance in long-hole blast drilling.
Civil Engineering: Ground reinforcement and foundation drilling in infrastructure projects.
