The DARK Blunt-End Flame Diamond Nail Drill Bit 2.1 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 narrow flame shape with a rounded, blunt tip, this diamond nail drill bit provides excellent access to hard-to-reach areas around the cuticle while maintaining precise control. Its blunt-end design helps reduce the risk of accidental scratches compared with sharply pointed flame bits when used with proper technique.

The blue medium grit offers stronger abrasiveness than fine-grit diamond bits, making it particularly suitable for thick, dense, moist, and moderately rough cuticles that require more effective removal of keratinized tissue.

With its 2.1 mm diameter and 10 mm working head, this professional diamond bit is ideal for detailed cuticle preparation, cleaning narrow lateral sinuses, and refining thicker skin around the nail plate.

PROFESSIONAL WORKING RECOMMENDATIONS

• For optimal results, use the DARK Blunt-End Flame Diamond Bit with an appropriate e-file speed, minimal pressure, and controlled movements.
• 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 narrow 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.
• Professional Tip: Blue medium-grit diamond bits are particularly effective for clients with thicker or moist cuticles that are difficult to process with softer abrasives. The blunt-end flame shape provides controlled access to lateral sinuses, while the 2.1 mm diameter allows precise cleaning of narrow 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.
