Drill rod is a tool that connects drill bit and is matched with rock drilling machine to drill in the rock or soil. According to the internal and external thread form of the drill rod, It mainly includes extension rod and MF rod.
MF rod is a drill rod with external thread at one end and internal thread at the other end.
For MF rod, we use mature friction welding technology to increase the using life of thread.
Our MF drill rods are made of high-intensity alloy steel imported from Sweden and Shanghai Baogang steel group. All the trails and threads are formed by high precision CNC machines.Holistic carburization increases the carbon content in the outer layer of drill rod and hardened outer steel body.
When it comes to precision drilling in mining, tunneling, and construction, professionals rely on tools that deliver durability, speed, and accuracy. The R38 Speed Rod stands out as one of the most dependable choices in the top hammer drilling segment. Designed for high-impact performance and optimized energy transmission, the R38 Speed Rod ensures efficiency in even the most challenging environments.
The R38 Speed Rod is a male/male drill rod built with the R38 thread profile, offering superior joint stability and torque resistance. This rod is specifically engineered for rock drilling applications where equipment needs to perform under extreme pressure and vibration. The “Speed Rod” designation indicates a fast-change design that simplifies rod handling and reduces connection time, improving job site productivity.
The R38 Speed Rod brings a variety of technical and operational benefits:
Thread Design Efficiency: The R38 thread geometry is crafted to reduce wear and extend the rod’s life, ensuring a secure fit that maintains alignment during high-speed drilling.
Robust Material Construction: Forged from premium-grade alloy steel and heat-treated to enhance hardness and tensile strength, this rod resists fatigue and damage.
Enhanced Percussion Energy Transfer: Thanks to its solid core and tight thread interface, the R38 Speed Rod transfers energy from the drill to the bit with minimal loss.
Quick Coupling Mechanism: Its fast-change system allows for rapid connection/disconnection, minimizing delays and labor costs during rod exchanges.
Anti-Rust and Corrosion Resistance: A corrosion-resistant coating improves longevity in wet or chemically active environments.
The R38 Speed Rod is a top choice across various industries and applications:
Mining and Quarrying: Perfect for long-hole production drilling in underground mines and surface quarries.
