KAT DRILLING
1 / 5
Taper drill rod is essentially used for rock drilling, blasting holes, and other drilling works in quarries, coal mines, traffic construction, and other engineering projects. It is designed to work seamlessly with taper drill bits and is available in different lengths for various applications.
The basic principle is that the taper drill rods and taper drill bits must share the same tapered degree to ensure a secure fit and efficient power transfer. For light-duty rock drills, a 7° or smaller taper is common, while heavy-duty drills primarily utilize 11° or 12° angles.
