Material Performance Advantages
420J2 Stainless Steel
Achieves high surface hardness (HRC 50-55) through heat treatment, providing exceptional wear resistance and extended cutting edge retention for drilling dense cortical bone.
17-4PH Stainless Steel
Gains strength through precipitation-hardening (HRC 40-45), offering uniform high strength-to-weight ratio and excellent fatigue resistance for superior chipping and breakage resistance.
