Threaded Drill Pipe R22 R25 R28 R32 R38 T38 T45 T51 Wear Resistant Rock Drill Extension Rod

The R22, R25, R28, R32, R38, T38, T45, and T51 are internationally recognized codes for a range

of threaded drill rods, categorized primarily into two families: the R-series (generally for top-hammer

 drilling) and the T-series (often for down-the-hole (DTH) and other drilling methods). These codes

specify the thread type and dimensions, ensuring compatibility and optimal performance between

 the rod, drill bit, and drilling equipment.

Drill rod using thread system. Drilling precision can be further improved by using this as the first rod in a normal drill string.
Furthermore, since this is a speed rod design it will produce straighter holes and at least 10% higher penetration rate in good
rock conditions compared to rod and coupling sleeve combination system.
Widely used in drifting, tunneling, benching, and long hole drilling
