Product details

Drill Steel Round

It is common practice to bump up the drive end of Extension drill steel for added strength at the rock drill end to accommodate larger diameter and shank adapters. Drill steel of rock drilling tools is available in many standard lengths to match the drill feeds on a multitude of available drifting jumbos. A rock drill bit diameter closer to the steel diameter can be used since the coupling does not enter the hole, this enhances flushing and hole accuracy.

With Hexagon body from 25mm to 38mm (1”-1 1/2”) and Round body from 32mm to 51mm(1 1/4”-2”). Lengths 610mm to 6096mm(2’-20’). Avaliable with all popular international thread forms.
