"The"carbide bur ÜLKA blue cone, with its 6 mm head and its active part of 15 mm, is an essential tool for nail professionals who want to combine efficiency, gentleness, and precision in their technical gestures. It is ideal for working quickly on large surfaces while offering excellent maneuverability. Its blue grain, of medium grit, allows for versatile work without being harsh or overheating the nail, perfect for nail technicians who care about their clients' comfort.
This drill bit is particularly suitable for removing semi-permanent polish.-permanent, soft gels, or for shaping gel or acrygel constructions. Thanks to its conical profile, it allows reaching curved areas, nail edges, or arches, without creating marks or streaks. The diameter of 6 mm offers a comfortable sanding surface, allowing for faster work and optimizing service times, especially during complete removals or leveling after a fill.
It also allows for smoothing a gel surface before applying the top coat, or for removing material residues without affecting the underlying structure.-The blue grain ensures a balanced abrasion: it removes just enough without being too aggressive, which is ideal for sensitive nails or clients who are sensitive to heat.
For optimal results, this milling cutter should be used with a professional sander set between 8,000 and 15,000 RPM (revolutions per minute), depending on the material being worked on. It is advisable to always make continuous movements, without exerting excessive pressure. The correct technique is to "brush" the material, letting the cutter do the work, in order to avoid any unpleasant heating sensation.
Also consider changing the direction of rotation depending on the area being worked on (right or left side of the nail) to maintain a natural movement and avoid snags. If you work in mobile services, using this drill bit can significantly reduce your filing time and limit fatigue, especially during long sessions such as stiletto, Russian almond, or ballerina nail applications.
Like any carbide tool, this milling cutter must be carefully cleaned and disinfected after each use. Use a soft metal brush to remove the fine dust that can get embedded between the grooves. For perfect hygiene, prefer autoclaving or, if not available, cold sterilization with a suitable product. Allow to dry completely before storing it in a rigid holder, protected from shocks and moisture.
It is important not to use this drill bit on the raw natural nail. Although its grit is medium, it remains abrasive enough to damage the keratin of the nail plate if misused. Reserve-there for use on technical materials or on a very thin base layer during a filling.
In the salon, this drill is perfect for performing services back-to-back without losing comfort. It allows for quickly moving from one client to another while maintaining a high level of quality. For independent professionals or enthusiasts working from home, it represents a good compromise between efficiency and ease of use, especially if you perform various types of applications with different products (semi...-permanent, gel, resin, acrygel...).
It is also suitable for regular use on loyal clients, to maintain a stable level of service without damaging the nail plate. By alternating with softer or more precise bits depending on the areas, you can structure a sanding plan perfectly adapted to each application.
This burr can be used from the removal phase to the leveling of the surface before finishing. It is particularly useful for:
Thanks to its fluid cut and good grip, it facilitates repetitive movements and contributes to a quick, clean, and snag-free installation. It is an excellent ally for maintaining a neat and professional finish, even during busy workdays.
