The DARK Sharp Flame Diamond Nail Drill Bit 2.1 mm – Blue Medium Grit is a professional e-file attachment designed for precise cuticle lifting, pterygium removal, lateral sinus cleaning, and detailed nail preparation during hardware and combined manicures.

Featuring a slim 2.1 mm flame-shaped working head with a pointed tip, this diamond nail drill bit provides excellent access to narrow, hard-to-reach areas around the natural nail. Its sharp flame shape allows nail technicians to clean lateral nail folds, open the cuticle pocket, and remove nonliving tissue with precision and control.

The blue medium grit offers stronger abrasiveness than red soft grit, making it particularly suitable for normal, thicker, denser, and moist cuticles. Its high-quality diamond coating effectively removes keratinized skin and buildup while supporting consistent, controlled filing.

Unlike blunt-end flame bits, the sharp flame design features a pointed tip that provides greater access to tight lateral sinuses and narrow cuticle areas. Combined with medium abrasiveness, this bit is especially useful for experienced nail technicians who need efficient cuticle preparation without unnecessary repeated passes.

PROFESSIONAL WORKING RECOMMENDATIONS

• For optimal results, use the DARK Sharp 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 light, smooth movements without excessive pressure.
• Maintain the correct working angle when lifting the cuticle and cleaning lateral sinuses.
• Keep the bit moving to minimize friction and heat buildup.
• Exercise additional caution when using the pointed tip near delicate nail folds.
• Avoid pressing the sharp tip directly into the natural nail plate or living skin.
• Work only on nonliving cuticle tissue and superficial keratinized skin.
• Avoid using medium grit on extremely thin, sensitive, inflamed, or damaged skin.
• For delicate or sensitive cuticles, consider the red soft-grit version instead.

Professional Tip: The 2.1 mm sharp flame diamond bit with blue medium grit is particularly effective for cleaning dense or moist cuticles and narrow lateral sinuses. Its pointed tip provides precise access, while the medium diamond coating helps remove buildup efficiently. Because of its more abrasive surface and pointed shape, this bit is best suited for technicians experienced with e-file manicure techniques.

CLEANING, DISINFECTION & STERILIZATION

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

• 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.
• 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.
• Disinfection
