Taper drill rod is used for rock drilling, blasting holes and other drilling works in the quarries, coal mines, traffic and other contractions. It works with taper drill bits and has different length for various applications, our taper drill rods come in a variety of taper angles, generally, the light duty rock drill usually use 7 taper or smaller taper angle, the heavy duty rock drill mainly use 11f=12 taper angle. And the basic theory is that taper drill rods and taper drill bits must be in the same tapered degree. We provide tapered rods in a full range of shank configurations and steel hex diameters for hand-held pneumatic drilling needs. 1,1+Steel grade: 55SiMnMo++40SiMnCrNiMo, 95CrMo equivalent to SANDBAR 20 or C253, 2,Shank size: hex.22mmf-108mm , hex.22mmf-159mm, hex.22mmf-80mmhex.25mmf-108mm. hex. 3,Taper:6fp++7fp++11fp++12fp++etc 4,Length:0.5m-9m 5,Package: in wooden case or in bundles. 6,Supply ability:3000MT/month 7,Delivery time :30days 8,Payment terms:T/T or L/C.
The pneumatic pick is a tool with compressed air as its power. The compressed air is distributing alternatively through the tube-shaped distributing valve into either end of the cylinder, so that the hammer is reciprocating motion in it, which impacts the tail-end of the pick rod and drives the pick rod into the rock or strata of mine, thus causing them to split into pieces.
