Introduction of Extension Drill Rod/ Thread Drilling Rod:
Extension rod, also named Extension drill steel or Extension drill rod or Extension steel or 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.
Drifter rod, another names are tunneling steels, tunneling rod, drifting drill rod, has Round and hexagon rod available, most of drifting drill steel with drill Steel Hexagon is for tunneling and drifting drilling application. Hexagon rods are more rigid, heavier and transfer energy more efficiently,while increasing flushing.
