Taper drill rod is specifically engineered for rock drilling, blasting holes, and other intensive drilling works in quarries, coal mines, and various construction traffic projects. Designed to work seamlessly with taper drill bits, these rods are available in different lengths to suit a wide range of applications.
Our tapered rods feature various taper angles tailored to your needs: light-duty rock drills typically utilize a 7° taper or smaller, while heavy-duty rock drills primarily use 11° or 12° taper angles. It is essential for operational efficiency that taper drill rods and bits match in degree.
