|Applications:||Widely used in mining, quarrying, exploration, water-well, geothermal, solar and construction/geotechnical drilling projects|
Drill rods are widely used in water well drilling, mining, quarry, etc. We use seamless steel tube to produce the drill rods and carry on heat treatment of materials, internal thickening technology, tempering process after friction welding. Friction welding is the important process to manufacture the drill rods. It is solid-state joining technique that welds workpieces by generating heat through mechanical friction. We have the powerful friction welding machine that imported from South Korea to produce the high quality drill rods.
We offer a variety of drill rods as below:
Connection Thread: API 2 3/8’’Reg、API 2 7/8”Reg、API 3 1/2” Reg etc
Wall thickness: 5mm/6mm/8mm/10mm/12mm/14mm/18mm
As we have adequate stock of 76mm drill rod in stock, a quick delivery is available to meet urgent order.

Adopting seamless steel tubes from famous domestic large steel enterprises to produce drilling rod
Professional CNC machine was applied in all of the connection thread processing
Heat treatment of materials and friction welding are carried on to weld the threads with steel tubes to strengthen the drill rods.
With many years experiences of production of DTH drilling tools, the DTH drill rods we made have long service life.
All around after-sales service
Our sales will response to any questions within 24 hours once we get. We pay great attention to the feedback from clients and satisfy them both on products and services.
warranty: The warranty period is six months since the drill rods are delivered.
