Products Description
KATDRILLS Taper Drill Rod
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 11,12 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.

Taper Drill Rods primary uses:
1.Transmit power from rock drills to tapered drill bits in rock drilling operations
2.Applied for rock drilling and blasting in mining, quarrying and tunnel construction
3.Used for drilling operations in civil engineering, water conservancy and transportation projects
4.Core component for borehole drilling in open-pit and underground rock excavation works
Features
1.A precision carburizing process is employed to boost surface hardness, endowing the drill rods with outstanding wear resistance and an extended service life.
2.OurTaper drill rods are manufactured from 23CrNi3Mo,40SiMnCrNiMo,55SiMnMo, 95CrMo alloy steel, a high-performance material that matches the quality caliber of Sandvik Sandbar 64.
3.Unbeatable cost-performance ratio – top-tier operational performance offered at a highly competitive price.
4.A comprehensive range of drill rod specifications is available, fully tailored to meet the demands of diverse drilling scenarios and working conditions.
