High Quality DTH Drill Rod 60mm 76mm 89mm 102mm Mining Drilling Pipe Price

Product Description

Down-the-Hole (DTH) Drill Rod
drill rod is a critical component in drilling systems, specifically designed for efficient and high-performance rock drilling operations. It serves as the connecting link between the drill rig and the DTH hammer, transmitting both rotational force and compressed air to the hammer assembly. Constructed from high-strength, wear-resistant alloy steel, the drill rod ensures durability and reliability even under extreme conditions, such as high impact loads and abrasive environments. Its threaded connections are precision-machined to maintain air tightness and withstand intense vibrations, enabling deep and straight hole drilling with minimal deviation. Ideal for mining, quarrying, construction, and geothermal applications, the DTH drill rod enhances drilling efficiency, reduces operational downtime, and supports consistent penetration rates in hard rock formations.
Usually we are offering 50mm, 60mm, 76mm, 89mm, 95mm, 102mm, 114mm, 127mm, 140mm, 159mm.

Water well drill pipe is a kind of drilling tool that uses alloy steel pipe to thicken the upsetting at both ends, and connect with tool joints by friction welding. The quality of the drill pipe mainly depends on the selection of materials and the strength of the joint thread. Good materials are not easy to bend or break due to fatigue. The dense tissue after the end upsetting can effectively improve its mechanical properties and strength of the connection.
Features:
1. The end is heated by intermediate frequency, hydraulically upset, and heat treated, which effectively eliminates the internal stress of pre-processing,which has stable and reliable performance. 
2. The tool joints are made of 42CrMoA material, which is quenched and tempered after rough machining, and subjected to surface nitriding treatment after finishing.
3. The threads are all cut and formed by CNC lathe forming inserts, with precise coordination and strong interchangeability.
