Description
WTF04 Craniotomy Drill Bit Attachment
Precision Neurosurgical Cranial Access System
Product Overview
The WTF04 Craniotomy Attachment is a specialized neurosurgical drill bit system designed for precise cranial bone removal during craniotomy procedures. Engineered to deliver exceptional cutting performance with maximum patient safety, this attachment system features an 8mm cutting blade channel diameter and 116mm working length, optimized for controlled skull penetration in various neurosurgical applications.
Available in four head diameter sizes (6mm, 8mm, 10mm, 12mm) with a consistent 68.8mm effective cutting length, the WTF04 system provides surgeons with versatile options to match specific patient anatomy and surgical requirements. Each drill bit is precision-manufactured to ensure clean, efficient bone cutting while minimizing thermal damage and reducing the risk of dural injury.
Key Features & Benefits
1. Precision-Engineered Cutting Blade Design – Clean, Efficient Bone Removal
The WTF04 craniotomy drill bit features an advanced multi-blade cutting geometry optimized for cranial bone resection. The precision-ground cutting edges deliver smooth, consistent penetration through both outer and inner cortical bone layers, reducing surgical time and improving procedural efficiency.
- Multi-Blade Geometry: Optimized blade configuration balances cutting speed with control
- Sharp Cutting Edges: Precision-ground edges ensure clean bone cuts with minimal chatter
- Uniform Cutting Force: Even load distribution across blades reduces vibration and improves surgeon control
- Reduced Thermal Damage: Efficient cutting design minimizes frictional heat generation
- Smooth Bone Surface: Leaves clean, smooth bone edges for better healing and reconstruction
2. Four Head Diameter Options – Versatility for Every Procedure
The WTF04 system is available in four head diameter sizes (6mm, 8mm, 10mm, 12mm), providing surgeons with flexible options to match specific surgical needs. From small burr hole creation to larger craniotomy openings, there's an optimal size for every neurosurgical indication.
- 6mm (LHZT060C0688): Ideal for small burr holes, ventricular access, and minimally invasive procedures
- 8mm (LHZT080C0688): Versatile standard size for general craniotomy applications
- 10mm (LHZT100C0688): Larger diameter for faster bone removal in standard craniotomies
- 12mm (LHZT120C0688): Maximum size for large cranial openings and complex procedures
- Consistent Effective Length: All sizes feature 68.8mm effective cutting length for uniform performance
3. Optimized Working Length & Channel Diameter – Perfect Procedural Balance
With an 116mm overall working length and 8mm cutting blade channel diameter, the WTF04 attachment is engineered to provide the ideal balance between reach, stability, and cutting efficiency for cranial procedures.
- 116mm Working Length: Optimal reach for standard craniotomy approaches while maintaining stability
- 8mm Channel Diameter: Optimized blade channel for efficient chip evacuation and cooling
- Balanced Geometry: Proper length-to-diameter ratio minimizes deflection and maximizes control
- Ergonomic Integration: Designed for seamless integration with standard neurosurgical drill handpieces
4. Premium Medical-Grade Materials – Durability & Biocompatibility
Manufactured from high-quality medical-grade materials, the WTF04 craniotomy drill bit delivers exceptional durability, edge retention, and biocompatibility required for neurosurgical applications.
- High-Grade Stainless Steel / Tungsten Carbide: Premium cutting materials for long-lasting sharpness
- Medical-Grade Construction: Meets ISO 10993 biocompatibility standards
- Corrosion Resistant: Withstands repeated sterilization cycles without degradation
- Precision Machining: Tight manufacturing tolerances ensure consistent performance
- Autoclavable: Compatible with standard hospital sterilization protocols
5. Enhanced Safety Features – Patient Protection as Priority
The WTF04 system incorporates design features that enhance procedural safety, reducing the risk of complications during cranial drilling procedures.
- Controlled Penetration: Optimized blade geometry provides tactile feedback when breakthrough occurs
- Reduced Tearing Risk: Clean cutting action minimizes dural tear risk during inner table penetration
- Stable Cutting: Low-vibration design improves surgeon control and accuracy
- Efficient Chip Evacuation: 8mm channel design prevents clogging and overheating
- Predictable Performance: Consistent cutting characteristics surgeons can rely on
