R28 Hex And Round Shape Threaded Drill Rod For Rock Drill ,
Tungsten Carbide Material
Thread drill rod other names extension rod, Extension drill steel,
Extension drill rod, and Extension steel, M/F rod ( Speedrod ) ,
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 extension steel is characterized by a
duplicate thread on each end of the steel.
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
We can offer many kinds of drill bits, including chisel type bits,
cross type bits, tapered drill rods and integral drill rods, mainly
used for mining, coal cutting, tunneling, rock cutting in
quarrying.
