KAT DRILLING
1 / 5
Taper drill rod is used for rock drilling, blasting holes and other drilling works in quarries, coal mines, traffic construction, and other contractions. It works 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° and 12° taper angles. It is essential that taper drill rods and taper drill bits share the same tapered degree for optimal performance.
