Product details

Rock drilling tools manufacturer Prodrill, DTH Drill Pipes

DTH drill tubes are used for connecting DTH hammer and DTH button bits rock drill bits, they are made from seamless tubes. Tubes play a significant role in all DTH drilling, regardless of application, rock type, hole depth or drill rig. The key features of a high quality DTH tube are durability, accuracy and manageability.

ALL DTH drill tubes are friction welded, and usually the threads are standard API connections, like 2 3/8" API REG thread, 3 1/2" API REG thread or API IF thread, etc. According to customers request, from 1000mm to 5000mm length of tubes, O.D we can offer 50mm, 60mm, 76mm, 89mm,102mm,114mm，127mm，140mm.
