CNC T38 Thread Drill Rod For Underground Rock Drilling Tools

Hexagonal Rods: Recognized for their superior rigidity and weight, hexagonal rods provide more efficient energy transfer from the drill rig to the drill bit, resulting in increased percussive force and faster penetration rates. Their flat surfaces also create larger flushing channels, significantly improving the removal of drill cuttings and debris from the borehole.

Round Rods: Generally lighter and more flexible than their hexagonal counterparts, round rods are the preferred choice for many extension drilling applications, especially in longer drill strings where reduced weight can minimize energy loss and improve handling.

1. Proprietary Heat Treatment & Carburization:
2. To maximize performance and service life, our drill rods undergo a specialized carburization process as part of their heat treatment. This advanced technique involves diffusing carbon into the surface of the steel at high temperatures. The result is an exceptionally hard, wear-resistant exterior that maintains a tough, shock-absorbent core. This process hardens the rod uniformly from the inside out, significantly enhancing its resistance to abrasion, bending, and fatigue failure, thereby extending its operational longevity.
3. Premium Material Selection:
4. We utilize only high-strength alloy steel sourced from top-tier international manufacturers. This ensures a consistent, high-quality metallurgical structure that forms the foundation of a durable and reliable drill rod.
5. Precision CNC Machining:
6. All threads are meticulously machined using Computer Numerical Control (CNC) systems. This guarantees perfect thread form, pitch, and alignment, ensuring seamless, secure connections between rods and with other drill string components. Precise threads are critical for efficient energy transfer and preventing premature thread failure.

1. Underground Mining: Essential for extracting valuable metals and minerals from deep underground deposits, providing the robust linkage needed for high-impact drilling.
2. Drifting and Tunneling: Used in creating linear passageways (drifts) to connect underground work sites and in the construction of large, sealed tunnels for ore transport and infrastructure.
3. Benching and Long Hole Drilling: Critical in benching operations, which involve horizontal drilling to create ledges for excavation, and in long hole drilling for creating vertical or inclined shafts to access deep ore bodies.
4. Quarrying and Open-Pit Mining: Employed in quarrying for extracting dimension stone, limestone, and other materials at shallower depths, and in large-scale open-pit mining operations that require deep, high-volume drilling.
