Prodcut information:
Also named taper rod, tapered drill steels etc.This provides a hexagonal shank 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).
Tapered drill rod Advantage:
1. Through-hardened and heat-treatment shank end for high wear
resistance and a longer service life
2. Stainless steel flusing tube lining to prevent corrosion and
breakage
3. Super tough 23CrNi3MoA, 40SiMnCrNiMo or 55SiMnMo steel,
specially designed for wet or dry drilling.
4. Special anti-corrosion oil to protect the flushing hole of the
rod.
