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

Diamond nail drill bit, model DFL 2.3-8.0M. Flame shape with 2.3 mm diameter, medium grit, and 8.0 mm working part. Designed for cuticle preparation, pterygium removal, and lateral nail fold treatment during e-file manicures and pedicures. Medium abrasive handles thicker cuticle tissue more efficiently than fine-grit versions, reducing treatment time per client. The 8.0 mm working length suits standard cuticle zones on both hands and feet. For technicians who need extended reach on larger nail beds, KMIZ also offers the DFL 2.3-10M with a 10.0 mm working part. Manufactured by KMIZ (est. 1931) on Swiss precision equipment. ISO certified. CE marked. Shank diameter: 2.35 mm (3/32"). Working part length: 8.0 mm. ISO: 866.104.243.080.023.

• 5‑Pack KMIZ Nail Drill Bit DFL 2.3-8.0M - medium-grit diamond flame bits with a 2.3 mm head designed for cuticle preparation and pterygium removal during e-file manicures and pedicures. The flame profile reaches lateral nail folds, sinuses, and the proximal groove with controlled precision. The 2.3 mm width combined with medium abrasive provides efficient material removal on average to wider nail beds. 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 removes pterygium and keratinized tissue faster than fine-grit equivalents, requiring fewer passes to fully expose the nail plate. The 2.3 mm diameter provides more contact surface per stroke than the narrower 2.1 mm variant, covering the cuticle zone more efficiently on standard-sized nail beds. Operates at low to medium RPMs with consistent abrasion depth, allowing the technician to maintain control while working through denser tissue.
• Used for dry cuticle technique in Russian manicure on clients with thicker pterygium or longer intervals between appointments. Effective for lifting dense cuticle tissue, cleaning the proximal fold, and preparing lateral walls before gel, builder base, or acrylic application. Also used in pedicure cuticle prep where tougher skin requires more abrasive initial treatment. Pairs with a fine-grit 2.3 mm flame (DFL 2.3-8.0F) for smoothing after the medium-grit pass.
• Standard 3/32" (2.35 mm) shank fits all professional electric nail file machines. Lightweight, balanced construction ensures stable rotation with minimal vibration at working speeds. Compatible with both right- and left-handed handpieces. The 8.0 mm working part length provides full visibility during cuticle work, allowing precise control in tight treatment areas.
• ISO 866.104.243.080.023. 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.
