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
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.
Male/female (m/f) rod, speed rod M/f drill steel is an alternative to couplings sleeves to include the female part of the threaded connection as an integral part of the drill steel. M/f drill steel provides more rigid connections and is easier to uncouple and handle. The service life also tends to be better than with separate couplings. The advantages of drilling with m/f steel include: easy handling, quicker uncoupling, tighter connections, the potential to drill straighter holes, and longer service life.
