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.
