The Cone Bit 4.0 mm Coarse is a professional carbide drill bit created for fast, efficient removal of artificial materials and thickened skin. Its tapered cone-shaped design allows precise access to tight or deep areas, making it a versatile tool for both manicure and pedicure tasks.

With its Coarse abrasive texture, this bit delivers strong cutting power while maintaining clean, controlled removal. It handles gel, acrylic, polygel and builder products with ease, speeding up correction work and significantly reducing the time needed to remove bulky or reinforced overlays.

Common uses include:
• fast removal of gel and acrylic
• reducing thickness of builder overlays
• shaping during correction and refill
• pedicure: removing rough callus and hardened skin
• working along deep sidewalls and narrow grooves
• thinning and contouring product in tight areas

The 4.0 mm tip offers an ideal blend of precision and removal power, enabling access to areas where larger bits may cause discomfort or lack accuracy. Its design is especially effective for detailed pedicure areas and deep nail folds.

The bit is made from high-quality tungsten carbide, ensuring long-lasting sharpness and resistance to wear. It operates smoothly with minimal vibration, providing comfort and control for the technician and a pleasant experience for the client.

Suitable for all standard 3/32" (2.35 mm) e-file handpieces, the Cone Bit 4.0 mm Coarse can be sterilized using any salon-approved method: autoclave, ultrasonic cleaning or disinfectant solutions.

This bit is an essential tool for professionals who need reliable performance, fast removal capability and precise work in difficult and narrow zones.
