• 5‑Pack KMIZ Nail Drill Bit DFL 2.3-8.0F — fine-grit diamond flame bits with a 2.3 mm head designed for detailed cuticle work and pterygium removal during e-file manicures and pedicures. The flame profile tapers from a wider midsection to a pointed tip, allowing the technician to reach lateral nail folds, sinuses, and the proximal groove with controlled precision. 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 coating removes dead skin and pterygium in thin, even layers without catching or overheating. The 2.3 mm diameter provides slightly more surface contact than a 2.1 mm flame, making it effective for clients with average to wider nail beds where more coverage per pass is needed. Operates best at low to medium RPMs, giving the technician consistent tactile feedback and full control over abrasion depth during soft tissue work.
• Primary tool for dry cuticle technique in Russian manicure: exposing the nail plate along the eponychium, cleaning pterygium from the surface, and smoothing lateral folds before gel or builder base application. Also used in e-file pedicures for cuticle prep on larger toes and for refining sidewall buildup. Commonly included in professional cuticle bit sets alongside 2.1 mm flame, ball, and cylinder shapes for a complete prep workflow.
• Standard 3/32" (2.35 mm) shank fits all professional electric nail file machines. Lightweight, balanced construction ensures smooth rotation with minimal vibration at working speeds. Compatible with both right- and left-handed handpieces. The 8.0 mm working part length provides adequate reach for most cuticle zones while maintaining full visibility of the treatment area.
• ISO 856.104.243.080.023. Head diameter: 2.3 mm. Working part length: 8.0 mm. Shank: 2.35 mm (3/32"). Diamond abrasive retains grit consistency through repeated autoclave sterilization cycles. Designed for use by trained nail technicians and podiatrists. The bit should be selected individually for each client and fully sterilized between uses.
