• 5‑Pack KMIZ Nail Drill Bit DFL 2.1-8.0F - fine-grit diamond flame bits with a compact 2.1 mm head, purpose-built for cuticle preparation and pterygium removal during e-file manicures and pedicures. The narrow flame profile reaches tight lateral nail folds and sinus areas where wider bits cannot operate safely. Manufactured by KMIZ - a medical instrument factory established in 1931, producing on Swiss Rollomatic CNC equipment with ISO 9001 and ISO 13485 certification.
• Fine diamond abrasive provides gentle, controlled exfoliation of dead skin and pterygium without generating excess heat or irritating live tissue. The tapered working surface allows graduated contact pressure - the tip accesses narrow zones while the wider midsection covers more surface area when needed. Designed for low-RPM technique, enabling the technician to maintain tactile feedback throughout the procedure.
• Used for dry cuticle technique in Russian manicure: cleaning the eponychium, lifting and removing pterygium from the nail plate, and refining lateral folds before product application. Also suitable for pedicure cuticle prep on smaller toes where standard flame bits are too wide. Commonly paired with ball or cylinder bits for a complete cuticle care workflow.
• Standard 3/32" (2.35 mm) shank fits all professional e-file machines. Balanced construction ensures stable, vibration-free performance at low to medium RPMs. Compatible with both right- and left-handed handpieces. The compact 8.0 mm working part length provides full visibility of the treatment area, reducing the risk of accidental tissue contact during detailed work.
