Sansung rock drilling extension rod are produced with high high quality of alloy steel bar and tungsten carbides with excellent put on resistance and effect toughness excellent, via heat therapy so that it can face up to the toughe EPT rock drilling calls for, and transmit intensive effect vitality into the rock with the lea EPT attainable decline of strength. They are commonly utilised in all sorts of mining, drilling, quarrying, engineering, design, drinking water properly drilling, oil exploring industries and so forth.

 

Extension rod:

EPT names are Extension drill metal, Extension drill rod, and Extension steel, M/Frod (Pace rod), make Hexagonal and round cross-sections,Hexagonal rods are much more rigid, heavier and transfer energy much more successfully,whilst escalating flushing. Spherical rods are typically lighter than hexagonal rodsand are typically used in extension drilling apps. With the more time metal tending to be more substantial in diameter, traditional extension metal is characterizedby duplicate thread on every conclude of the steel.
Extension rods are produced by hollow drill steels, various lengths are available from 600mm to 6400mm. This hollow gap are typically named flushing hole, used for transmitting h2o or air for the duration of drilling. And the threads can be used for connecting couplings, shanks adapters or bits.

Male/Female (M/F) rod, pace rod:

M/F drill metal is an option to couplings sleeves to incorporate the female part of the threaded link as an integral component of the drill metal. M/F drill metal offers more rigid connections and is less difficult to uncouple and deal with. The service life also tends to be much better than with separate couplings. The rewards of drilling with M/F steel include: simple managing, a lot quicker uncoupling, tighter connections, the prospective to drill straighter holes, and for a longer time service daily life.
For extension rod and M/F steel approach, the below two distinct types of warmth treatment are utilised to strengthen large speed and potent percussive drill string parts to optimize their functionality and reliability. More time steel more substantial in diameter, standard extension steel, Hexagonal and round cross sections are offered.

Carburizationis a process utilized to more challenging the total rod floor the two internally and externally to reinforce and increase the lifestyle of the rod.

High frequency induction is process in which only the thread finishes of the rod are hardened to lengthen thread daily life.
