Efficient Hole Opener: Precision Medical Drill Bit for Surgical Applications
Precision Medical Drills: Reliable Stainless Steel Drilling Tools are high-performance cutting instruments engineered for creating clean, accurate, and consistent holes in bone, biometals (like titanium and cobalt-chrome alloys), and high-strength polymers during surgical procedures. Manufactured from medical-grade stainless steel (such as 420 or 17-4PH), these drills are heat-treated to achieve an optimal balance of hardness, sharpness, and torsional strength.
Product Processing
The manufacturing process prioritizes metallurgical integrity, geometric precision, and sterility assurance. Using CNC precision grinding machines with diamond/CBN wheels, complex helical flutes and precise point geometry are formed. The drills undergo controlled hardening to achieve 55-60 HRC, followed by intensive ultrasonic cleaning and chemical passivation (per ASTM A967) to maximize corrosion resistance.
