Extension Rod
Create Hexagonal and spherical cross sections, Hexagon rods are a lot more rigid, heavier and transfer power more successfully, although increasing flushing. Round rods are generally lighter than hexagonal rods and are typically used in extension drilling purposes. With the for a longer time steel tending to be larger in diameter, typical extension steel is characterized by a replicate thread on each and every finish of the steel.,

Male/Feminine (M/F) rod, pace rod
M/F drill metal is an alternative to couplings sleeves to incorporate the female element of the threaded connection as an integral portion of the drill steel. M/F drill metal offers far more rigid connections and is easier to uncouple and handle. The service existence also tends to be far better than with individual couplings. The positive aspects of drilling with M/F metal contain: Straightforward managing, faster uncoupling, tighter connections, the prospective to drill straighter holes, and for a longer time support life.
For Extension Rod and M/F metal method, the below two diverse varieties of warmth treatment method are utilised to reinforce higher pace and powerful percussive drill string components to improve their performance and trustworthiness. Lengthier metal larger in diameter, typical extension steel, Hexagonal and round cross sections are accessible.
– Carburization is a method used to harden the complete rod surface area the two internally and externally to strengthen and increase the life of the rod.
– High Frequency Induction is a method exactly where only the thread ends of the rod are hardened to lengthen thread lifestyle.
