Taper drill rod is essentially used for rock drilling, blasting holes, and other drilling works in quarries, coal mines, traffic projects, and other construction sites. It works in conjunction with taper drill bits and is available in different lengths for various applications.

Our taper drill rods come in a variety of taper angles. Generally, light-duty rock drills use a 7° taper or smaller, while heavy-duty rock drills mainly utilize 11° or 12° taper angles. The core principle is that the taper drill rods and taper drill bits must share the same tapered degree to ensure a secure fit and efficient energy transfer.
