Underground Mining Rock Drill Rod With CNC Milling Integral Drill
Rod
Description
Integral Drill rod is used by a hand held drill machine in
Underground mining and for small hole drilling, equipped with small
power rock drills, like air leg rock drills, hand held rock drills,
etc. It can reduces the expense of impact energy, improves the
drilling speed and efficiency, also it can be used for drilling
bore hole diameter from 30mm to 41mm usually. Regarding Integral
drill steels,the quality of a steel material and a tungsten carbide
is very important to get good drilling performance.
Within the Dimensional Stone Quarrying Industry, hole sizes are
generally quite small (Ø25-34mm) and are therefore too small to
accommodate threaded equipment. H19 Chisel Bit Integral Rods with
H19 x 108mm shank are suitable for the smaller hole ranges, between
Ø25-27mm. Smallest available size is Ø23mm.
