420J2 & 17-4PH Stainless Steel Medical Drill Bits / Trephines

Category	Details
Product Description	These professional-grade medical drill bits and trephines are precision-engineered from two distinct high-performance stainless steels to meet specific surgical demands. 420J2 provides exceptional wear resistance and cutting edge retention, while 17-4PH offers superior overall strength and toughness. Both undergo a mandatory electrochemical passivation process, creating a robust, inert surface that ensures outstanding corrosion resistance, enhanced biocompatibility, and reliable performance in rigorous surgical environments.
Product Application	Designed for precise and efficient bone drilling, cutting, and trephination in a wide range of surgical procedures. • Orthopedic Surgery: Fracture fixation, joint replacement, and bone plate/screw placement. • Neurosurgery: Cranial burr holes and spinal procedures. • Dental & Maxillofacial Surgery: Bone preparation for implants and osteotomies. • Trauma Surgery: Where high-strength, reliable instruments are critical.
Technical Parameters	• Material: 420J2 Martensitic Stainless Steel / 17-4PH (ASTM 630) Precipitation-Hardening Stainless Steel • Hardness (Core): 420J2: ≥ HRC 50-55 / 17-4PH: ≥ HRC 40-45 (H900 Condition) • Surface Treatment: Electrochemical Passivation per ASTM A967 / ISO 16048 • Corrosion Resistance: Excellent resistance to physiological saline and disinfectants, compliant with relevant ASTM/ISO standards. • Biocompatibility: Compliant with ISO 10993-5 (Cytotoxicity) and ISO 10993-10 (Sensitization). • Sterilization: Compatible with autoclaving (steam), gamma radiation, and EtO gas.
Material Hardening Advantages	• 420J2 Hardening Advantage: Achieves high surface hardness primarily through heat treatment (quenching and tempering). This results in exceptional wear resistance and the ability to maintain a sharp cutting edge for longer periods, even when drilling through dense cortical bone. It is ideal for applications where blade sharpness longevity is paramount. • 17-4PH Hardening Advantage: Gains its high strength and toughness through a precipitation-hardening heat treatment process. This treatment precipitates copper-rich phases throughout the matrix, providing a uniform, high strength-to-weight ratio and excellent fatigue resistance. This makes it exceptionally resistant to chipping, torsion, and breakage under high-stress conditions, ensuring procedural safety.
