BIT UNDER REFILL LONG

Long Carbide Underrefill Bit – Maximum Precision for Under-Nail Filing (Medium Abrasiveness) The performance of a flawless maintenance service depends on the perfect cleaning of the area beneath the extension. The YAS Beauty Lab Long Underrefill Bit is a high-precision professional tool made of premium carbide, specifically designed to access difficult areas and finish the nail architecture from underneath. With an extended length of 1.5 cm, this e-file bit offers total visibility and control during the "natural nail cleaning" procedure at the maintenance appointment. Technical Specifications & Salon Benefits Durable Material (Carbide): The high-quality carbide alloy ensures a fast and uniform cut, withstanding repeated use and sterilization processes (dry heat sterilizer/autoclave) without losing its sharp edge. Extended 1.5 cm Length: The "Long" format is designed to reach deep areas under the nail, allowing you to work without the e-file handpiece obstructing your view of the client's nail. Universal Medium Abrasiveness: The medium grit is ideal for the rapid removal of technical material residue or the natural nail grown under the construction, leaving a clean and smooth surface without deep filing marks. Heat Dissipation: The carbide structure is optimized to minimize heating during rotation, providing increased comfort to the client even at higher speeds. Balance and Stability: The perfect centering of the shaft prevents vibrations in the handpiece, protecting your e-file bearings and ensuring linear filing without skips. Recommended Use & Pro Tip This bit is the "hero" of the Refill (Maintenance) procedure. Use it to thin the free edge from underneath and to completely eliminate the natural nail that tends to detach from the technical material. Pro Tip: A correctly cleaned nail from underneath prevents the appearance of air pockets and maintains the "new nail" look for a longer period. Set your e-file to a medium speed and ensure you are supporting the client's finger firmly to maintain the precise angle needed for under-nail cleaning.
