Tapered Drill Rods Suppliers and Manufacturers

Tapered rods

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.

One end connect with the shank end, the other end connect with bit end. Transmit the impacting power and torque from shank to bit, the lifespan depends on the material, thread processing. ï?¬ Made from the same steel as Sandvik; 23CrNi3Mo, which is in same league as Sandvik Sandbar 64, is applied as drill rod material. ï?¬ Friction welding workmanship . It makes the thread and the body integrated without broken. ï?¬ Advanced production process: produced by CNC machining and advanced heat treatment. It will connect the drill rod and the drill bit more better. â?¢ Optimize processing procedure, entirely automatic threading equipment to finish the thread naturally and reduce the concentration of stress. ï?¬ Full-carburization drill rod for high wear-resistance and strength. Carburizing process is applied to promote surface hardness, thus grant better wearing quality and lifespan for the drill rods; ï?¬ Quality close to world famous brands, but our prices are much more competitive. ï?¬ Complete types of drill rod for various drilling scenarios. Advanced engineering, precision manufacturing and high-grade materials assures the reliable quality of our drill rod. When you send inquiry, please tell the information as following: Diameter + length +thread

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.
