Description
Precision Engineering for Delicate Interventions
SNK's Superior Cannulated Drill redefines low-speed bone surgery with unparalleled control. The brushless motor generates ≥260W power at 0–300 RPM (±10% accuracy), producing ≥20Nm torque to drill through brittle or osteoporotic bone without microfractures. The 4.5mm hollow shaft enables real-time K-wire guidance, reducing procedural errors by 50% in spinal and reconstructive surgeries. With radial runout <0.1mm, surgeons achieve sub-millimeter accuracy—critical for pedicle screw placement and joint preservation.
Medical-Grade Durability & Sterilization Compliance
Crafted from surgical 316L stainless steel, the drill withstands 500+ autoclave cycles (151°C sterilization, battery excluded). Brushless technology ensures zero maintenance and 50,000+ operational hours—5× longer than brushed alternatives. Advanced vibration dampening maintains ≤55dB noise levels, while thermal controls limit surface temperature to ≤50°C during extended use, preventing tissue necrosis.
Product Detail
Why SNK Excels in Low-Speed Precision
- Controlled Power: High torque at low RPM prevents bone thermal necrosis.
- Guided Accuracy: Hollow core enables live K-wire visualization.
- Efficient Workflow: 60-minute charging for 6+ hours of runtime.
- Tissue Protection: Low heat/noise minimizes iatrogenic trauma.
Critical Applications & Solutions
Optimized for precision-demanding procedures:
- Spinal Fusion: Pedicle drilling in osteoporotic bone.
- Pediatric Orthopedics: Epiphyseal plate-sparing procedures.
- Fragility Fractures: Osteoporotic hip/pelvis reconstruction.
- Dental/Craniomaxillofacial: Precision bone grafting.
Stepless speed control allows tactile feedback adjustment for varying bone densities, while the balanced ergonomic design (1.45kg) enables single-handed operation in confined spaces. Compatible with SNK's HRC53+ drill bits (Ø0–8mm) for ceramic-like bone surfaces.

Frequently Asked Questions
What is the speed range and torque capacity of the SNK Cannulated Drill?
The drill operates within a speed range of 0–300 RPM (with ±10% accuracy) and delivers a high torque output of ≥20 Newton/meters (Nm), making it ideal for low-speed, high-precision bone surgery.
Is the entire drill autoclavable?
The drill body and components are fully autoclavable up to 151°C. However, please note that the battery pack is excluded from sterilization and must be removed before autoclaving.
How does the brushless motor benefit surgical procedures?
The brushless motor provides zero-maintenance operation, extends service life to over 50,000 hours, maintains low noise levels (≤55dB), and controls surface temperature below 50°C to prevent bone thermal necrosis during extended use.
What size of guide wires can be used with the hollow shaft?
The drill features a Ø4.5mm hollow core shaft, which allows real-time K-wire guidance to ensure precise alignment and reduce procedural errors in spinal and reconstructive surgeries.
What is the battery charging time and runtime performance?
Equipped with Pulse Tech charging technology, the battery fully charges in just 60 minutes, providing efficient and reliable power for continuous surgical workflows.
What materials are used to construct the SNK Cannulated Drill?
The drill is constructed from medical-grade surgical 316L stainless steel, ensuring excellent corrosion resistance and the durability to withstand more than 500 autoclave sterilization cycles.
