Original KMIZ Nail Drill Bit [5‑Pack] – Diamond Flame, 2.3 mm, Medium Grit, 3/32" Shank – E‑File Bit for Cuticle Prep, Pterygium Removal & Nail Fold Treatment

Diamond nail drill bit, model DFL 2.3-10M. Flame shape with 2.3 mm diameter, medium grit, and an extended 10.0 mm working part. Designed for cuticle preparation, pterygium removal, and lateral nail fold treatment during e-file manicures and pedicures. The longer working length provides more contact surface per stroke than standard 8.0 mm flame bits, reducing repositions and improving treatment speed on clients with thicker cuticle tissue. The 2.3 mm head width suits average to wider nail beds. Recommended as the primary medium-grit flame in high-volume salons where session efficiency matters. Follows the two-step workflow: medium grit for initial clearing, fine grit for finish work. Manufactured by KMIZ (est. 1931) on Swiss precision equipment. ISO certified. CE marked. Shank diameter: 2.35 mm (3/32"). Working part length: 10.0 mm. ISO: 866.104.243.100.023.

• 5‑Pack KMIZ Nail Drill Bit DFL 2.3-10M — medium-grit diamond flame bits with a 2.3 mm head and an extended 10.0 mm working part, designed for cuticle preparation and pterygium removal during e-file manicures and pedicures. The combination of medium abrasive and longer working length makes this bit effective for full-perimeter cuticle treatment in fewer repositions. Manufactured by KMIZ - a medical instrument factory established in 1931, producing on Swiss Rollomatic CNC equipment with ISO 9001 and ISO 13485 certification.
• Medium diamond grit cuts through dense pterygium and keratinized skin efficiently, reducing the number of passes compared to fine-grit variants. The 10.0 mm working part - 2.0 mm longer than the standard 8.0 mm flame — provides extended surface contact, allowing continuous strokes along the proximal fold and lateral walls without lifting the bit. Operates at low to medium RPMs with predictable abrasion depth, suited for technicians who work with steady, sweeping motions.
• Built for dry cuticle technique in Russian manicure on clients with thicker tissue, overgrown pterygium, or longer intervals between appointments. The wider 2.3 mm head covers average to larger nail beds effectively, while the extended working part reaches deeper into lateral sinuses without repositioning. Also suited for pedicure cuticle prep where tougher foot skin requires more aggressive initial treatment. Pairs with a fine-grit flame for smoothing and a ball bit for final refinement in a multi-step cuticle workflow.
• Standard 3/32" (2.35 mm) shank fits all professional electric nail file machines. Balanced construction ensures stable, vibration-free rotation at working speeds. Compatible with both right- and left-handed handpieces. The longer working part reduces the need for frequent angle changes, helping lower hand fatigue during back-to-back client sessions.
• ISO 866.104.243.100.023. Head diameter: 2.3 mm. Working part length: 10.0 mm. Shank: 2.35 mm (3/32"). Diamond abrasive retains grit consistency through repeated autoclave sterilization cycles. Designed for trained nail technicians and podiatrists. The bit should be selected individually for each client and fully sterilized between uses.
