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.
