Carburized Hexagonal Body Thread Drill Rod Underground Rock Drilling Tools
Product features Of Hexagonal Body Thread Drill Rod:
The R32-H28-R28 Thread Drill Rod is a premium-grade extension rod engineered for demanding drilling operations. This product, central to percussive drilling systems, is also commonly known as Extension Drill Steel, Extension Drill Rod, M/F Rod, or Speedrod. It is manufactured to exacting standards, ensuring superior performance and durability in the most challenging environments.
This extension rod is designed to connect the drilling machine to the drill bit, transmitting impact energy and rotation deep into the rock formation. It is available in two primary cross-sections: hexagonal and round. The R32-H28-R28 model features a hexagonal profile, which offers distinct operational advantages. The hexagonal design provides greater rigidity and a more robust structure compared to round rods, leading to more efficient energy transfer from the rock drill to the bit. This results in higher penetration rates and improved drilling efficiency. Furthermore, the geometry of the hex rod enhances the flushing of drill cuttings, ensuring a cleaner hole and reducing the risk of the rod becoming stuck.
Specifications Of Hexagonal Body Thread Drill Rod:
| Thread Type | R32-H28-R28 |
| Technology | Fully carburized |
| Rod Type | Hexagonal |
| Length | 2400mm |
| Weight | 11.9kgs |
| Material | Manufactured from high-strength, high manganese alloy steel sourced from top-tier international steel mills. This ensures exceptional toughness and the ability to withstand high-impact stress. |
| Processing | The rods are precision-machined on Computer Numerical Control (CNC) equipment to guarantee perfect thread geometry and dimensional accuracy. This is followed by a proprietary heat treatment and carburizing process, which hardens the surface for extreme wear resistance while maintaining a tough, shock-absorbent core. |
Adavantages Of Hexagonal Body Thread Drill Rod:
Superior Material Quality: The use of high-grade, imported alloy steel provides a foundational advantage in strength and fatigue resistance.
Precision Engineering & Advanced Heat Treatment: The combination of CNC milling and a specialized heat treatment process ensures optimal hardness, depth, and microstructure. The carburizing process enriches the surface with carbon, creating an extremely hard, wear-resistant outer layer that significantly extends service life.
Exceptional Durability: The product is built to resist abrasion, bending, and fatigue failure, resulting in lower cost-per-meter drilled and reduced downtime for rod changes.
Optimized Performance: The hexagonal design ensures maximum energy efficiency and effective hole cleaning, contributing to faster, more productive drilling cycles.
Applications Of Hexagonal Body Thread Drill Rod:
Construction Works: Foundation drilling, site preparation, and anchoring.
Energy & Mining: Quarrying, open-pit and underground mining, and mineral exploration.
Rock Drilling & Tunneling: Civil engineering projects such as road and railway tunnels, hydroelectric projects, and underground infrastructure development.
