Carburized Hexagonal Body Thread Drill Rod with R32-R28 Thread and 2400mm Length for Rock Drilling

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.

• Hexagonal design provides greater rigidity and robust structure for efficient energy transfer
• Enhanced flushing of drill cuttings ensures cleaner holes and reduces sticking risk
• Higher penetration rates and improved drilling efficiency

• Superior Material Quality: High-grade imported alloy steel for strength and fatigue resistance
• Precision Engineering & Advanced Heat Treatment: CNC milling and specialized heat treatment for optimal hardness
• Exceptional Durability: Resists abrasion, bending, and fatigue failure for lower cost-per-meter drilled
• Optimized Performance: Hexagonal design ensures maximum energy efficiency and effective hole cleaning

• Construction Works: Foundation drilling, site preparation, and anchoring
• Energy & Mining: Quarrying, open-pit and underground mining, and mineral exploration
• Rock Drilling & Tunneling: Road and railway tunnels, hydroelectric projects, and underground infrastructure
