Typically made from high-strength steel, the rock drill shank is hardened and tempered to endure extreme pressure and impact loads. The material selection and heat treatment processes ensure it can withstand the intense forces exerted during drilling, resisting deformation and fracture even under harsh conditions. Some advanced models may incorporate tungsten carbide inserts for enhanced wear resistance, extending the lifespan of the shank.
