Product Description
Efficient Hole Opener: Precision Medical Drill Bit for Surgical Applications
Product Description
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. They feature precision-ground flute geometries and cutting edges designed for efficient chip evacuation, minimal thermal generation, and reduced surgical trauma. As critical, single-use or reusable (with proper sterilization) tools, they are the cornerstone of reliable and predictable performance in demanding orthopedic, dental, and surgical applications.

Product Processing
The manufacturing process prioritizes metallurgical integrity, geometric precision, and sterility assurance.
The manufacturing process prioritizes metallurgical integrity, geometric precision, and sterility assurance.
Material Selection & Forming: Medical-grade stainless steel rod (e.g., 420J2, 17-4PH) is selected, straightened, and cut to blank size. The blank is then precision-ground to the required shank diameter.
Flute & Point Grinding: Using CNC precision grinding machines with diamond/CBN wheels, the complex helical flutes and precise point geometry (e.g., 118° standard point, 90° bone point) are formed. This creates sharp, consistent cutting edges and optimal flute profiles for chip removal.
Heat Treatment (Hardening & Tempering): The drill undergoes a controlled hardening process to achieve high surface hardness (e.g., 55-60 HRC for 420 steel) followed by tempering to restore necessary toughness and reduce brittleness, ensuring it can withstand torsional and bending loads.
Final Finishing & Sharpening: After heat treatment, the cutting edges and flutes are finished and honed to razor sharpness. The entire tool undergoes precision polishing to achieve a smooth, low-friction surface finish that reduces tissue adhesion and facilitates cleaning.
Cleaning, Passivation & Inspection: Drills undergo intensive ultrasonic cleaning and chemical passivation (per ASTM A967) to maximize corrosion resistance. Each drill is 100% inspected for critical dimensions, cutting edge sharpness, and visual defects.
