DTH Drill Rod Exporters in Africa
DTH Drill Rod Exporters in Africa
Hitu Engineering specializes in manufacturing drill rods for heavy drilling operations. We are one of the leading DTH drill rod exporters in Africa, supporting the mining, quarrying, water well drilling and construction industries. We construct as per the American Petroleum Institute (API) standards, making us an export-friendly DTH drill rod supplier in Africa. We make them by the standard friction welding method and use high-strength steel alloys. Tool and tube joints are heat treated for achieving the desired wear resistance. The threads are regular or Internal Flush, precision-machined by CNC for accurate fitting. The bore is straight for a smooth and unobstructed compressed air passage from the drilling rig to the hammer.
We provide rods in multiple sizes, varying in thickness, outer and inner diameter, thread dimension, and thread type. Our standard rod outer diameters are 73 mm, 89 mm, 114 mm, 127 mm and 139 mm.
Qualities of Our Drill Rods
While designing our drill rods, we consider the challenges of percussive impacts, torsional loads, vibrations and tensile and compressive stresses. To overcome these challenges, we have engineered our drill rod machining processes with superior technologies. Here are the key reasons why our DTH drill rods are the preferred choice for buyers in Africa:
- With excellent fatigue resistance, the rod can withstand high impact forces, axial loads and high torque.
- Superior toughness to absorb shock and vibrations during hammering.
- Resilience to the abrasive rock formations.
- Accurate thread fit with proper alignment.
- Leak free air passage with minimal pressure drop.
- Resists the heat damage due to friction, and impact, and high-pressure compressed air.

FAQs
– The key purpose of DTH drill rods is to connect the hammer inside the bore to the drilling rig on the ground and also to supply compressed air with a smooth flow.
The American Petroleum Institute (API) sets the globally accepted standards for down-the-hole drilling threads. It develops the safety and technical standards for REG (Regular) and IF (Internal Flush).
The right size of drill rod should be selected based on hammer size, rock formation, borewell depth, drill rig capacity and air compressor output.
The service life of DTH drill rods depends on quality of steel, manufacturing methods used, usage and maintenance during operations.
