Original KMIZ Nail Drill Bit [5‑Pack] - Diamond Tornado Flame, 2.1 mm, Medium Grit, 3/32" Shank - E‑File Bit for Dry Cuticle Work, Pterygium Removal & Tough Lateral Folds - model DTO 2.1-10M

Diamond nail drill bit, model DTO 2.1-10M (Item #: 118195). Tornado flame shape with 2.1 mm diameter and medium grit. A proprietary KMIZ design featuring spiral diamond coating with open channels between abrasive bands — unlike standard continuous-coated flames, the Tornado resists clogging, generates less heat, and lasts longer through repeated use and sterilization. Specifically effective on very dry lateral folds, thick cuticle, and dense pterygium where standard diamond flames work too slowly. The 10.0 mm working part provides extended reach for full-perimeter treatment. Use as the primary clearing tool on tough tissue, then follow with a fine-grit standard flame for smoothing. 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: 866.104.243.100.021.

• 5‑Pack KMIZ Nail Drill Bit DTO 2.1-10M — medium-grit diamond Tornado flame bits with a 2.1 mm head and 10.0 mm working part, designed for cuticle preparation and pterygium removal during e-file manicures and pedicures. Tornado is a proprietary KMIZ design featuring spiral diamond coating instead of continuous abrasive coverage — an open-channel construction that outperforms standard flame bits on dry, tough tissue. Manufactured by KMIZ — a medical instrument factory established in 1931, producing on Swiss Rollomatic CNC equipment.
• The spiral abrasive pattern alternates diamond-coated bands with smooth open channels along the working surface. This design prevents clogging — debris clears through the channels instead of packing into the abrasive. The interrupted contact reduces friction and heat buildup, while the medium-grit diamond bands maintain aggressive cutting action on each pass. The result: faster material removal on dry, hard tissue with longer bit life than standard continuous-coated diamond flames.
• Built for dry cuticle technique on the most demanding tissue types: very dry lateral folds, thick and fleshy cuticle, and dense pterygium that resists standard flame bits. Lifts the cuticle "skirt" cleanly and quickly without multiple slow passes. Also effective for cleaning the proximal fold and preparing lateral walls before gel, builder base, or acrylic application. The 10.0 mm working part provides extended reach for full-perimeter cuticle treatment in fewer repositions. Pairs with a fine-grit standard flame for finishing after the Tornado completes initial clearing.
• Standard 3/32" (2.35 mm) shank fits all professional electric nail file machines. Balanced construction ensures stable rotation with minimal vibration at low to medium RPMs. Compatible with both right- and left-handed handpieces. The 10.0 mm working length covers the full cuticle zone in continuous strokes, and the clog-resistant design means less stopping to clean the bit mid-procedure - reducing interruptions and overall session time.
• ISO 866.104.243.100.021. Item #: 118195. Head diameter: 2.1 mm. Working part length: 10.0 mm. Shank: 2.35 mm (3/32"). Proprietary KMIZ Tornado spiral diamond coating. Designed for trained nail technicians and podiatrists. The bit should be selected individually for each client and fully sterilized between uses.
