Hex Extension Rod - Tapered drill rods – Gimarpol Detail:
Gimarpol’s Tapered Drill Rod with 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 drill bit in the end.
