T45 Drill Bit Extension Rod Speed Rod For Mining Quarring Tunneling Blasting

Description:

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. With the longer steel tending to be larger in diameter, conventional

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.

Feature of the extension rod MF rod:

Drill rod using thread system. Drilling precision can be further improved by using this as the first rod in a normal drill string. Furthermore, since this is a speed rod design it will produce straighter holes and at least 10% higher penetration rate in good rock conditions compared to rod and coupling sleeve combination system.
Widely used in drifting, tunneling, benching, and long hole drilling

High strength chromium-molybdenum steel with high fatigue strength and excellent wear resistance

Type: Hex. Drifter Rod, Extension Rod, Speed Rod, MF-Rod
