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.
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).

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.

DTH Drill Rods (Tubes/Pipes) and Sub Adaptors: Acedrills has DTH drill rods with several different thickness designs for each diameter, made from different grade steels for selection. So, in practice of field drilling, under different condition, there may be in need of different kinds of drill rods for particular application. For example, the thicker ones with general high quality grade steel for drilling hole of average depth, such as blasting holes; and the thinner ones with better grade steel for drilling hole of very deep, such as drilling for ground thermal. Moreover, Acedrills DTH drill rods are also well heat-treated, precision manufactured, and friction-welded.

Prismatic drill rod refers to prismatic tapered drill pipe used for coal tunnel exploration, also called triangular drill pipe, anti sloughing hole drill pipe, ABS pipe. With prismatic steel pipe as rod body and thread or hex or square joint as connection type, it is manufactured by the friction welding craft. Prismatic drill rod pipe is widely used in the coal seam and similar geological conditions for coal mine water exploration and gas drainage borehole construction, and can also be used in anchorage and drilling in the field of geophysical prospecting and construction of water conservancy engineering.
Our company manufactures Wireline Drill Rods, BQ, NQ, HQ, PQ, PHD, Parallel Threaded Drill Rods, DCDMA Sizes AW, BW, NW, HW, and Metric sizes 42 mm, 50 mm, 60 mm to 90mm.
Note:
1. Thread oil should be used when screwing the drill rod and hammer knocking should be prohibited.
2. The drill rod stand should have buffer materials, like wood, rubber, and more. The contact between the threaded ends and iron tools should be forbidden.
3. During the relocation of drill rod, the thread protector should be screwed on the threaded parts so as to protect it from damages.
Dual-wall drill pipes is used for R. C. drilling, when it works, circulating medium is following through the gaps between the dual-wall pipes, carrying samples out of the holes efficiency, meanwhile, it can protect the hole from collapse, matching up with our R.C. air(water) swivel, GQ air-driven hollow DTH hammer can complete getthe samples constantly.
