The Large Rounded Top Bit 6.6 mm Extra Coarse is a professional carbide drill bit designed for extreme removal speed combined with enhanced safety. Its large 6.6 mm working diameter allows rapid processing of wide nail surfaces, while the rounded top geometry reduces the risk of injury when working close to the cuticle, sidewalls or natural nail plate.

The Extra Coarse abrasive level provides maximum cutting power, making this bit ideal for removing thick gel, acrylic and polygel overlays, as well as reinforced builder layers. It is specifically suited for heavy debulking, full product removal and demanding correction work where speed and efficiency are critical.

A key advantage of the rounded top design is improved safety. Unlike sharp-edged bits, it allows smoother contact with sensitive areas, helping prevent accidental cuts and making the tool more predictable during high-speed operation.

Key applications include:
• ultra-fast removal of thick gel, acrylic and polygel
• aggressive debulking of reinforced overlays
• full removal before reapplication
• correction and restructuring of nail architecture
• safer work near cuticle and sidewalls
• preparation before switching to medium or fine bits

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

Manufactured from premium tungsten carbide, the bit offers excellent wear resistance, long-lasting sharpness and low vibration at high RPM. Its balanced construction ensures control and comfort despite its aggressive cutting capacity.

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 Extra Coarse is the ideal choice for professionals who need maximum speed, power and added safety for demanding 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.
