PROFESSIONAL WORKING RECOMMENDATIONS

• For optimal results, use the DARK Ball Diamond Bit with an appropriate e-file speed, minimal pressure, and controlled movements.
• Select the rotation speed according to the client’s skin condition, treatment area, and equipment specifications.
• Use gentle, smooth movements without excessive pressure.
• Keep the bit moving continuously to reduce friction and heat buildup.
• Work only on properly prepared, nonliving cuticle tissue and superficial keratinized skin.
• Avoid prolonged contact with one area.
• Maintain the correct working angle when treating lateral nail folds.
• Do not use on irritated, inflamed, broken, or damaged skin.
• Choose a medium-grit diamond bit when working with significantly thicker or more resistant cuticles, if appropriate.

Professional Tip: Red soft-grit diamond bits are particularly useful for clients with delicate, thin, or dry cuticles. The 4.0 mm ball shape allows technicians to gently remove dead skin and achieve a smooth finish without unnecessarily aggressive exfoliation.

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 CKEANING
   Use an ultrasonic cleaner with a suitable instrument-cleaning solution when recommended by the manufacturer.
   Ultrasonic cleaning helps remove debris trapped between 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 the instrument’s service life.
4. DRYING
   Thoroughly dry the bit after cleaning and disinfection, following 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.
