The DARK Blunt-End Flame Diamond Nail Drill Bit 2.4 mm – Blue Medium Grit is a professional e-file attachment designed for efficient cuticle lifting, pterygium removal, lateral sinus cleaning, and precise treatment of the skin surrounding the natural nail during hardware and combined manicures.

Featuring a 2.4 mm flame-shaped working head with a rounded, blunt tip, this professional diamond nail drill bit provides a wider working surface for efficient cuticle preparation. Its carefully designed shape allows nail technicians to process thicker cuticles, clean lateral nail folds, and access hard-to-reach areas while maintaining precise control.

The blue medium grit is particularly suitable for dense, moist, thick, and moderately rough cuticles that require more effective abrasiveness. Its evenly distributed diamond coating supports consistent removal of keratinized skin and nonliving cuticle tissue.

Compared with the narrower 2.1 mm and 2.3 mm versions, the 2.4 mm diameter provides a slightly broader working surface, making it convenient for technicians who prefer faster processing of larger cuticle areas while maintaining accuracy.

• Select the rotation speed according to the client’s skin condition, nail anatomy, and equipment specifications.
• Use smooth, controlled movements without excessive pressure.
• Maintain the correct working angle when lifting the cuticle and cleaning lateral sinuses.
• Keep the bit moving continuously to minimize friction and heat buildup.
• Use the rounded tip carefully when accessing areas around the nail folds.
• Avoid prolonged contact with the natural nail plate.
• Work only on nonliving cuticle tissue and superficial keratinized skin.
• Do not use on inflamed, irritated, broken, or damaged skin.
• For thin or highly sensitive cuticles, consider a red soft-grit diamond bit instead.

Its medium abrasiveness supports efficient removal of keratinized tissue, while the rounded tip provides controlled access to lateral nail folds.

CLEANING, DISINFECTION & STERILIZATION

Proper maintenance helps preserve the diamond coating, maintain professional hygiene standards, and extend the service life of the bit.

1. Mechanical Cleaning
   After each use, remove visible dust, skin particles, and debris using a stiff-bristled plastic cleaning brush.
   Avoid metal brushes, which may damage the diamond coating.
2. Ultrasonic Cleaning
   Use an ultrasonic cleaner with a suitable instrument-cleaning solution when recommended by the manufacturer.
   Ultrasonic cleaning helps remove debris trapped between the diamond abrasive particles.
3. Disinfection
   Immerse the bit in a professional disinfectant compatible with diamond-coated instruments.
   Follow the disinfectant manufacturer’s recommended concentration, contact time, and rinsing instructions.
   Excessive disinfectant concentration may damage the diamond coating and reduce its service life.
4. Drying
   Thoroughly dry the bit after cleaning and disinfection according to the sterilizer manufacturer’s instructions.
5. Sterilization
   Sterilize using a compatible autoclave or dry-heat sterilizer.
   Follow the manufacturer’s validated temperature and sterilization cycle requirements.
6. Storage
   Store cleaned and sterilized bits in a dry, protected environment to prevent contamination and mechanical damage.
   For professional use only.
