Vacuum-brazed crown bur, Ø 2.3 mm

Hardened Stainless Steel Diamond-Coated Drill Bit (Ø 2.3 mm × L 6.5 mm)

Optimize effectiveness, performance, and precision in your advanced pedicures and podiatry services with the Vacuum Burr (Trephine) for Callus Extraction. Specifically designed for the specialized treatment of deep hyperkeratosis and heloma, this tool with a technical crown-shaped design and smooth sleeve is a key solution for achieving clean, fast, and painless extractions.

Made of **highly hardened stainless steel with a high-density diamond coating**, it combines remarkable wear resistance with a sharp cutting edge of maximum effectiveness. Although its crown-shaped geometry makes it an intuitive and ideal choice for professionals new to using trephines, its performance more than meets the demands of experienced podiatrists in targeted callus removal.

Advanced Synergistic Effect: Trephine / Crown Design, Hardened Stainless Steel, and Vacuum Evacuation

This technical burr integrates mechanical features developed for the direct treatment of keratinized lesions:

• Crown / Smooth Sleeve Geometry (Ø 2.3 mm × L 6.5 mm): Its hollow cylindrical head embraces the core of the callus or heloma, allowing for a clean circular cut without damaging the surrounding healthy skin.
• Aspiration / Mechanical Vacuum Effect: The hollowed-out trephine design helps to house and fluidly extract the keratotic core during rotation.
• Hardened Stainless Steel with Diamond Coating: Ensures sharp and durable cutting edges that maintain their effectiveness after continuous use.
• Gradation Indicator Ring: Incorporates a color marker on the shank for quick identification of the grit level and sharpness in your tool kit.
• Biosecurity and Sterilization: Chemically resistant material suitable for rigorous disinfection protocols and repeated autoclave sterilization cycles.

Technical Specifications and Product Parameters

Key Applications in Pedicure and Podiatry:

• Callus Core (Heloma) Extraction: Delimitation and effective removal of keratotic corns on the sole or toes.
• Treatment of Focal Hyperkeratosis: Circular emptying of circumscribed calluses difficult to access with conventional burrs.
• Initiation and Technical Work: Excellent tool for learning and improving trephine handling.

💡 Pro Tip for Professionals: When working with the 2.3 mm vacuum trephine, position the burr completely perpendicular to the callus core. Apply light pressure with brief, intermittent pulses at low to medium revolutions (5,000–9,000 RPM). This will allow the crown to border and isolate the lesion for easy removal without generating frictional heat on the patient's nerve endings.

Equip your practice with the Vacuum Burr (Trephine) for Calluses and ensure precise, safe, and high-standard professional extractions.
