Product Description

Professional Hole Opener: Reliable Medical Drill Bit in Stainless Steel

Product Description
Professional Robust Hole Cutters (High-Quality Medical Drill Bits) are precision-engineered surgical instruments designed for creating clean, accurate, and controlled holes in bone and other hard tissues during orthopedic, dental, neurosurgical, and other medical procedures. Characterized by exceptional strength, sharpness retention, and durability, these drill bits are manufactured from advanced medical-grade alloys and undergo rigorous processing to withstand the high torque and thermal stresses of surgical drilling. Their optimized flute design and specialized coatings ensure efficient chip evacuation, minimal thermal necrosis, and reduced operator fatigue.

Product Processing
Material Selection: Use of high-performance alloys such as Cobalt-Chromium (CoCr), Medical-Grade Stainless Steel (455, 465), or Tungsten Carbide (for tips).
Precision Grinding: CNC-controlled multi-axis grinding machines shape the drill geometry (point angle, clearance angle, flute helix) with micron-level precision.
Surface Enhancement: Electropolishing for a smooth finish and Physical Vapor Deposition (PVD) coatings like Titanium Nitride (TiN), Diamond-Like Carbon (DLC), or Zirconium Nitride (ZrN) for extreme hardness and lubricity.
Heat Treatment: Vacuum heat treatment and cryogenic processing to achieve optimal core toughness and edge hardness, preventing premature wear or fracture.
Laser Marking: Permanent etching of size, lot number, and sometimes depth markers.
Ultrasonic Cleaning & Passivation: Thorough cleaning to remove all contaminants and passivation for corrosion resistance.
Sterilization Validation: Validation for repeated sterilization cycles (Autoclave, Plasma, Gamma).
Quality Assurance: 100% inspection of critical dimensions, hardness testing, and functional testing on bone simulants.
Product Applications
Orthopedic Surgery: Drilling for screw placement in fracture fixation (plates, intramedullary nails), joint arthroplasty (hip, knee), and spinal fusion.
Dental & Maxillofacial Surgery: Implant osteotomy, bone grafting, and reconstructive procedures.
Neurosurgery: Burr hole creation for cranial access, craniotomy, and spinal procedures.

Technical Parameters

Material & Metallurgy	Core Material	Premium Surgical Stainless Steel (e.g., 455/465):High strength, good corrosion resistance. Cobalt-Chromium-Molybdenum Alloy (CoCrMo - ASTM F1537):Superior wear & fatigue resistance. Solid Tungsten Carbide (WC):Extreme hardness, brittle. Hybrid (Carbide Tips on Steel Shank):Combines cutting performance with toughness.
	Coating	Titanium Nitride (TiN - Gold):Classic, increases hardness & lubricity. Diamond-Like Carbon (DLC - Black):Ultra-low friction, biocompatible. Zirconium Nitride (ZrN):High corrosion resistance. Uncoated/Electropolished.
Design & Geometry	Point Angle	Standard:118° (general purpose).Orthopedic:90°-100° (for cortical bone).Self-Centering:90° with chisel edge.
	Helix Angle (Flute Design)	High Helix (~40°):Efficient chip evacuation in soft bone/cancellous bone. Low Helix (~20°):Greater strength for hard/cortical bone. Parabolic Flute:Enhanced chip flow.
	Tip Design	Standard Twist Drill, Brad Point (for precise entry), Trocar (sharp tip), Diamond Coated (for ceramics/composites).
Dimensions	Diameter Range	Micro:0.5 mm - 1.0 mm (for mini screws, dental). Standard:1.5 mm - 6.5 mm (orthopedic trauma). Large:7.0 mm - 15.0 mm (for reaming, acetabular prep).
	Working Length (Fluted Section)	Short:10 mm - 25 mm (for plates). Standard:30 mm - 60 mm. Long:70 mm - 150 mm (for intramedullary applications).
	Total Length (with Shank)	Designed to fit standard surgical drill chucks (e.g., Jacobs chuck, quick-connect). Common: 65 mm - 200 mm.
Mechanical Performance	Core Hardness (HRC)	Stainless Steel:50 - 55 HRC. CoCr Alloy:45 - 50 HRC (softer core, hard surface via work-hardening).
	Surface Hardness (Coated)	TiN Coating:~80 HRC (equiv. Vickers 2400). DLC Coating:~90 HRC (equiv.).
	Fatigue Strength	High-cycle fatigue tested (e.g., >50,000 cycles at specified torque).
Operational Performance	Cutting Efficiency	Optimized geometry reduces thrust force and heat generation.
	Chip Evacuation	Flute design prevents clogging, especially in deep holes.
	Thermal Management	Design and coatings reduce heat transfer to bone (< 47°C threshold to prevent necrosis).
Compatibility	Drive System/Shank Type	Round Shank (for Jacobs Chuck), Hex Shank (3-flat, 6-flat for power tools), Quick-Coupling (for specific drivers).ANSI/ISO standard sizes.
	Compatible Drill Speed (RPM)	Guidelines: -Small Diameter (1-2mm):800-1500 RPM. -Medium (2.5-4.5mm):500-1000 RPM. -Large (>5mm):200-500 RPM. Speed depends on material and irrigation.
