Sansung rock drilling extension rod are created with high high quality of alloy metal bar and tungsten carbides with exceptional use resistance and influence toughness exceptional, by way of warmth remedy so that it can face up to the toughe EPT rock drilling requires, and transmit intense influence vitality into the rock with the lea EPT attainable decline of power. They are widely used in all varieties of mining, drilling, quarrying, engineering, construction, h2o effectively drilling, oil exploring industries etc.

 

Extension rod:

EPT names are Extension drill metal, Extension drill rod, and Extension metal, M/Frod (Velocity rod), create Hexagonal and round cross-sections,Hexagonal rods are much more rigid, heavier and transfer strength more successfully,although escalating flushing. Round rods are generally lighter than hexagonal rodsand are usually utilised in extension drilling programs. With the lengthier steel tending to be larger in diameter, standard extension metal is characterizedby replicate thread on each conclude of the metal.
Extension rods are created by hollow drill steels, diverse lengths are obtainable from 600mm to 6400mm. This hollow gap are normally named flushing hole, used for transmitting water or air during drilling. And the threads can be utilised for connecting couplings, shanks adapters or bits.

Male/Woman (M/F) rod, speed rod:

M/F drill metal is an substitute to couplings sleeves to contain the female part of the threaded relationship as an integral part of the drill steel. M/F drill metal supplies far more rigid connections and is less complicated to uncouple and manage. The support daily life also tends to be greater than with individual couplings. The advantages of drilling with M/F metal incorporate: easy handling, more quickly uncoupling, tighter connections, the potential to drill straighter holes, and for a longer time service lifestyle.
For extension rod and M/F steel procedure, the under two diverse kinds of heat therapy are employed to reinforce large speed and powerful percussive drill string factors to improve their performance and reliability. For a longer time metal larger in diameter, conventional extension steel, Hexagonal and round cross sections are obtainable.

Carburizationis a process employed to more challenging the entire rod area each internally and externally to strengthen and increase the existence of the rod.

Large frequency induction is procedure the place only the thread finishes of the rod are hardened to lengthen thread daily life.
