The Large Rounded Top Bit 6.6 mm Coarse is a professional carbide drill bit designed for fast, controlled and safe removal of artificial nail materials. Its large 6.6 mm working diameter allows efficient processing of wide surfaces, while the rounded top geometry minimizes the risk of cuts or damage when working close to sensitive areas.

The Coarse abrasive level provides strong cutting performance, making this bit ideal for removing gel, acrylic and polygel overlays, reducing thickness of reinforced builder layers and performing correction work. Compared to medium cuts, it offers faster material reduction while still maintaining good control.

The rounded top is a key safety feature, especially when working near the cuticle zone, sidewalls and natural nail plate. It allows smoother transitions and helps prevent accidental injuries, making the bit suitable for both experienced technicians and busy salon environments.

Key applications include:
• fast removal of gel, acrylic and polygel
• bulk reduction of thick and reinforced overlays
• correction and reshaping of nail architecture
• smoothing uneven surfaces after removal
• safer work near cuticle and sidewalls
• preparation before switching to medium or fine bits

The 6.6 mm diameter increases productivity by covering more surface area with fewer passes. The cutter design promotes effective debris evacuation and heat dissipation, helping to maintain stable performance during prolonged use.

Manufactured from high-quality tungsten carbide, the bit delivers long-lasting sharpness, low vibration and predictable handling even at higher RPM. Its balanced construction ensures comfort and precision during daily professional use.

Compatible with all standard 3/32" (2.35 mm) e-file handpieces, the Large Rounded Top Bit supports all professional sterilization methods, including autoclave, ultrasonic cleaning and chemical disinfection.

The Large Rounded Top Bit 6.6 mm Coarse is an excellent choice for professionals who need speed, power and enhanced safety in everyday removal and correction procedures.

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.
