摘要： PROBLEM TO BE SOLVED: To provide an induction hardening process for forming a quench-hardening layer with a uniform thickness among dihedral angle parts and facial parts in a hexagonal hollow steel rod and the hexagonal hollow steel rod which offers a long drilling life and generates little chipping and bending in use. SOLUTION: In the induction hardening process, the hexagonal hollow steel rod is placed inside an annular high-frequency coil, and the coil and the rod are relatively moved toward their mutual central axes while performing heat quenching. Here, the coil and the rod are positioned apart from each other with their central axes being parallel to each other, and the rod is revolved around its central axis while being heated and quenched. This reduces difference in effective hardening depths between the dihedral angle parts and the facial parts of the rod and yields the rod showing an excellent wear resistance and a high fatigue strength.
