MF drill rod

Description

MF drill rod is an alternative to couplings sleeves to include the female part of the threaded connection as an integral part of the drill steel. M/F drill steel provides more rigid connections and is easier to uncouple and handle. The service life also tends to be better than with separate couplings. The advantages of drilling with M/F steel include: easy handling, quicker uncoupling, tighter connections, the potential to drill straighter holes, and longer service life.
For Extension Rod and M/F steel process, the below two different types of heat treatment are used  to strengthen high speed and powerful percussive drill string components to maximize their performance and reliability.  Longer steel larger in diameter, conventional extension steel, Hexagonal and round cross sections are available.
– Carburization is a process used to harden the entire rod surface both internally and externally to strengthen and extend the life of the rod.
– High Frequency Induction is a process where only the thread ends of the rod are hardened to lengthen thread life.

Performance

Our MF drill rods are made of high-quality alloy steel and advanced thread manufacturing technology, and have excellent performance in wear resistance and flexibility.  We offer speed drill rods with various threads, such as R23 MF drill rod, R32 MF drill rod, R38 MF rod, T35 MF rod, T38 MF drill rod, T45 MF rod, MF rod T51, GT60 MF drill rod, SR35 speed rod, etc

Application

The MF drill rod is mainly used for the following projects
• Underground mining
• Tunneling,quarrying
• Widely used in benching, and long hole drilling
