Technical Specifications and Product Parameters

Recommended Applications in Professional Settings:

• Russian and Hybrid Manicure: Precise cleaning of the periungual channel, cuticle lifting, and polishing with diamond bits.
• Sculpting and Removal of Synthetic Nails: Quick and controlled removal of gel, acrylic, acrygel, or composites without transferring heat to the natural nail.
• Pedicures and Therapeutic Podiatry: Treatment of thick nails, hyperkeratosis, corns, and preparation of the nail plate.

💡 Pro Tip: Always ensure a test bur or protective pin is inserted into the Twist-Lock chuck when the handpiece is not in use. Closing the mechanism without a shank inside can damage the internal clamping collet.
