World-Class Quality Rock Drilling Tools

Products Description

Tapered Drill Rod

Tapered drill rod, another name called taper rod, tapered drill steels. This provides a hexagonal chuck section to provide leverage for the rotation chuck bushing. It usually has a forged collar to maintain the proper shank striking face position in the rock drill, and a tapered bit end. Tapered rod lengths available from 0.6m to 3.6m in length (are measured from the collar to the bit end).

All products are compatible with many products manufactured by major global brands, and our products are widely used in mining, water well drilling, tunneling, quarrying, construction, and civil engineering projects.

Tapered Drill Rod Advantages

  • High Wear Resistance: Through-hardened and heat-treatment shank end for a longer service life.
  • Corrosion Prevention: Stainless steel flushing tube lining to prevent corrosion and breakage.
  • Premium Materials: Super tough 40SiMnCrNiMo or 55SiMnMo steel, specially designed for wet or dry drilling.
  • Enhanced Protection: Special anti-corrosion oil to protect the flushing hole of the rod.
