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.
