The COP2560EX T51 D63 770 shank adapter is engineered for maximum durability in high-power rock drilling. Designed specifically for the COP 2560EX series, this 770mm striking bar features a massive 63mm diameter and a heavy-duty T51 thread. It is built to transmit the immense impact energy of the 25kW+ drifter to the drill string with unmatched efficiency.
Why Our COP2560EX T51 D63 770 is the Industrial Standard?
Engineered for 2560EX Power: The COP 2560EX hammer delivers massive impact force. Our D63 770mm shank is weight-matched to the piston to ensure "perfect impact" timing, reducing internal reflections that damage the drifter.
T51 High-Torque Thread: The T51 system is the standard for heavy production. Our precision-ground threads minimize heat build-up and prevent "cold welding" under the extreme torque required for deep-hole drilling.
Ultra-Rigid 63mm Body: The D63 diameter provides maximum resistance to bending stresses. This ensures superior hole straightness even when drilling 100mm+ diameter holes in fractured rock.
Advanced Fatigue Resistance: Each shank undergoes shot peening after carburizing, adding a layer of compressive stress that significantly extends the fatigue life under high-frequency impact.
Primary Applications
The COP2560EX T51 D63 770 is the workhorse for:
Production Mining: Large-scale long-hole stoping.
Bench Drilling: High-efficiency blasting in hard rock quarries.
Civil Engineering: Foundation piling and large-section tunnel excavation.
