Heavy Duty Friction Welded Drill Rods
Designed for rotary and DTH drilling these rods are extremely strong and hard-wearing with tool joints friction welded to the rod tube, and all threads nitrided for superior wear resistance.
Available in diameters up to 5 1/2 ” (139.7mm) and effective lengths up to 6 metres, with various thread types including API, Beco, NWY, and Mayhew.
Normally supplied with square spanner flats at each tool joint and plastic thread protectors.
