Product Description

Advanced Hole Opener: Professional Medical Drill Bit for Precision Tasks

Product Description
Reliable Medical Drill Bits are high-performance, professional-grade stainless steel hole cutters designed for precision bone drilling and preparation in surgical environments. Engineered with advanced geometry and manufactured from medical-grade stainless steel alloys, these drill bits offer exceptional sharpness retention, wear resistance, and thermal management to ensure clean cuts, minimal bone necrosis, and efficient debris removal. Their robust construction and optimized design make them a trusted tool for orthopedic, dental, neurosurgical, and trauma procedures where accuracy and reliability are paramount.

Product Processing
Material Selection: High-grade medical stainless steel (e.g., 455, 465, or 17-4PH) or cobalt-chromium alloy for enhanced durability.
Precision Forging/Machining: Initial shaping of the drill blank via precision forging or CNC machining to achieve core geometry.
Multi-Axis CNC Grinding: Precision grinding of cutting edges, flute geometry, helix angle, and point angle using diamond/CBN wheels.
Surface Hardening & Coating:

Heat Treatment: Vacuum hardening and tempering to achieve optimal core hardness (HRC 50-60).
Surface Coating: Application of PVD coatings like Titanium Nitride (TiN) or Diamond-Like Carbon (DLC) to enhance wear resistance and reduce friction.
Electropolishing & Passivation: Surface smoothing and corrosion resistance enhancement.
Laser Marking: Permanent etching of diameter, length, and lot identification.
Sterilization Validation: Validation for repeated autoclave, plasma, or chemical sterilization cycles.
Functional Testing: Drilling performance testing on bone simulants or cadaveric bone to validate cutting efficiency and heat generation.
Product Applications
Orthopedic Surgery: Drilling for screw placement in fracture fixation, joint replacement (hip/knee/shoulder), and spinal fusion.
Dental & Maxillofacial Implantology: Osteotomy preparation for dental implants and bone grafting procedures.
Neurosurgery: Burr hole creation for cranial access, ventriculostomy, and spinal drilling.
Trauma & Emergency Surgery: Rapid, controlled drilling in poly-trauma cases.
Veterinary Orthopedics: Bone drilling in animal surgery.

Technical Parameters

Material & Metallurgy	Core Material	Premium Surgical Stainless Steel (455/465):High strength, corrosion resistance. Cobalt-Chromium (CoCrMo):Superior fatigue/wear resistance. Hybrid (Carbide-tipped):Extreme edge hardness with steel shank toughness.
	Surface Coating	Titanium Nitride (TiN):Gold coating, increases hardness & lubricity. Diamond-Like Carbon (DLC):Black coating, ultra-low friction, biocompatible. Uncoated/Electropolished:For standard applications.
Geometric Design	Point Angle	90°-100°:Optimized for cortical bone. 118°:General-purpose. 135°:For harder bone or reduced "walking."
	Helix Angle	High Helix (30°-40°):Aggressive chip evacuation in soft bone. Low Helix (15°-25°):Increased strength for dense bone.
	Flute Design	2-Flute Standard:Balanced cutting/clearance. 3-Flute:Smoother finish, less chatter. Parabolic Flute:Enhanced debris removal in deep holes.
