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.
