The Cone Bit 4.0 mm Medium is a versatile, professional carbide bit designed for controlled shaping, refining and smoothing during both manicure and pedicure procedures. Its narrow cone profile provides excellent access to deep or tight areas, allowing technicians to work where larger bits cannot reach.

The Medium abrasive level offers an ideal balance between efficiency and gentle performance. It removes product faster than fine bits without being too aggressive, making it perfect for reshaping overlays, smoothing uneven surfaces, correcting imperfections and working closely along the sidewalls and lower nail arches.

Main applications include:
• refining gel, acrylic and polygel overlays
• shaping and thinning product during correction
• smoothing uneven areas and transitions
• cleaning and detailing sidewalls
• pedicure shaping and working on compacted skin
• precise work in narrow grooves and tight spaces

The 4.0 mm diameter allows accurate control while maintaining enough removal strength for effective work. This makes the bit particularly useful for Russian manicures, structural refinements and detailed pedicure zones.

Made from premium tungsten carbide, the bit maintains its sharpness and provides clean, vibration-free operation. Stability at medium and high RPM ensures comfort for both technician and client.

Compatible with all standard 3/32" (2.35 mm) e-file handpieces, the bit is fully sterilizable — autoclave, ultrasonic cleaning and chemical disinfectants.

The Cone Bit 4.0 mm Medium is an essential tool for nail technicians who need precision, efficiency and reliability when working in difficult, narrow or detailed areas.

Lnail Precision is a premium professional line of tungsten carbide bits created for technicians who work across all areas: delicate nail prep, pedicure, callus removal, artificial nail correction, and podiatry procedures.
The ultra-fine GU10UF carbide (approx. 6% Co) delivers exceptional hardness, clean cutting performance, low run-out, and excellent stability — making these bits a reliable universal tool for daily use.

Thanks to precise geometry and micro-grain structure, Lnail Precision bits perform equally well in sensitive manicure zones and high-load pedicure or podiatry applications, including work on dense skin, hyperkeratosis, and hard materials such as gel or acrylic. This makes the line suitable not only for beauty salons but also for podiatry professionals using medical-grade equipment.

Each bit undergoes strict European-level quality control with run-out values below 0.02 mm, ensuring smooth operation without vibration. The tools maintain stability at high RPMs, minimize heat generation, and offer maximum comfort to both technician and client.

Lnail Precision bits are fully autoclave-safe at 134°C and withstand repeated sterilization cycles without losing cutting performance or structural integrity. The series includes a wide variety of shapes and cuts — from precise Flame and Needle bits to powerful Barrel and 5-in-1 designs — giving professionals full freedom to choose the right tool for any technique.

Lnail Precision is a universal, stable, and technologically advanced carbide bit series that meets the professional needs of nail technicians, pedicurists, and podologists.
