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.

DRILL RODS: The tool steel drill rod pieces (O-1, A-2, D-2, H-13, S-7, M-2, and W-1) are usually machined in the annealed state and then heat treated to make hardened, long lasting tools. The Applications Table below shows the classes, steel grades, hardening methods, and typical applications for Drill Rod. To use the table, find the class in the left column. To find out what is drill rod used for, find the steel grade in the table below and read the applications in the right column of the same row. DRILL PIPES: Available Ranges: Sizes : 3",3 ½", 4 ½" & 5 ½" Length : 5', 10', 13', 15', 20' & 30'
The drill rod is the part that links the drill bit and the shank adapter in the rock drill and undertakes the task of transmitting the impact energy to the drill bit, the rotational torque, and the flushing medium. In actual use, the force conditions of the drill rod are harsh, and it is easy to consume a large number of wearing parts. Product Category Drill rods include tapered drill rods and threaded extension rods according to their connection methods. Tapered drill rod: It is suitable for drilling shallow holes, the tail is connected with the rock drill using the shank adapter, and the tapered part of the head is connected with the drill bit. Threaded extension rods: It is more suitable for drilling deep holes. It can use a sleeve with female threads to connect two drill rods with male threads. With the deepening of the hole depth, multiple drill rods can be connected. It is very convenient to remove the rod from the connection after chiseling. Except by connection type, drill rods include light drill rods and heavy drill rods. Light drill rods include tapered drill rods, shank rods, and integral drill rods. Heavy drill rods mainly include drill rods used for drifting and tunneling rigs, benching drilling rigs, and Open-cutting drilling rigs. Length Light drill rods: 300mm-6000mm(without shank, the conventional length of the shank is 108mm). Heavy drill rods: 600mm-2000mm(Drill rods less than five meters are available). 1.

We have engaged in rock drill tools for over tens years.
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.
