Product Description
Top Hammer Drill Rod Introduction
The Top Hammer Drill Rod is a high-precision threaded rock drilling component engineered for drifting, tunneling and underground mining applications in complex rock and rough terrain conditions. Available in a full range of thread types from R22 to GT60 and diameters from Hex25 to RD60, these drill rods are manufactured from high-strength alloy steel imported from reputable steel mills, with CNC milling and proprietary heat treatment processes ensuring consistent quality and reliable performance.
Applications
- Drifting and tunneling in complex rock formations
- Underground mining drilling operations
- Top hammer drilling systems for mining and quarrying
- Rough terrain drilling with demanding accuracy requirements
Key Features
- High-Precision CNC Machining: Profiles and threads are formed by high-precision CNC machine tools for consistent dimensional accuracy.
- Mature Friction Welding Technology: For MF rods, proven friction welding technology is applied to increase thread service life.
- Overall Carburization Hardening: The carburization process increases carbon content on the outer layer of the rod and hardens the external steel body for improved wear resistance.
- Solid Thread Design: Solid threads fit closely against the inner wall of the drill bit, enabling high-accuracy drilling in complex rock and rough terrain conditions.
Advantages
- Full thread range: R22, R25, R28, R32, R38, T38, T45, T51, GT60
- Round and hexagonal rod profiles for different drilling systems
- High-strength alloy steel imported from reputable steel mills
- CNC milling and proprietary heat treatment for consistent quality
- Carburized outer layer for extended service life
- No MOQ for test and trial orders
