T38 Thread Tophammer Drilling Extension Rod for Drifting and Bench
Drilling
Product Specifications:
Sollroc extension rods are used throughout the world for top-hammer
production drilling in mining, tunnelling, construction and quarry
work. Extension rod, other names are Extension drill steel,
Extension drill rod, and Extension steel, M/F rod ( Speed rod ) ,
Produce Hexagonal and round cross sections, Hexagon rods are more
rigid, heavier and transfer energy more efficiently, while
increasing flushing. Round rods are generally lighter than
hexagonal rods and are normally used in extension drilling
applications.
Male / Female (M/F) rod, speed rod M/F drill steel 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.

Features:
1.Material are developed by cooperated with National & Local
Joint Engineering Laboratory for High-performance Metal Structure
Materials and Advanced Manufacturing Technology to improve the
fatigue resistance of drilling steel.
2.Material is from Baosteel with strict process of steel smelting
and rolling: Refining - Vacuum - Continuous casting - drilling hole
method - surface peeling to control the content of non metallic
inclusion and harmful element.
3.Strictly control precision thread process to avoid thread too hot
and broken effected by the high vibration and shaking of thread
part when it works.
4.Heat treatment: Fully Carburization - Air cool quenching -
tempering. It make the rod keep high toughness and improve surface
harness and whole strength as well.
5.Thread strengthen: enhance the thread parts to improve the
wear-resistance and longevity of the rod.
