Tapered Diamond Nail Drill Bit Set

This 5-piece set consists of tapered conical nail drill bits with a 0.35mm working diameter, crafted from polishing stone embedded with uniform diamond grit. Each bit features a 2.35mm stainless steel shank for broad compatibility with UK and EU electric nail drills. Total length is approx. 12mm; tip tapers to a fine point (~0.35mm at apex), with a maximum grinding surface width of ~2.5mm. Weight per bit is ~0.8g. Material is non-metallic polishing stone — optimised for controlled, cool-running abrading on keratin-based surfaces. Two defined grit levels support differentiated tasks: Fine (F) grit — marked by red ring — offers subtle, controlled removal ideal for live tissue proximity work like cuticle refinement; Medium (M) grit — marked by blue ring — delivers higher material removal rate for gel polish cleanup and thicker epidermal layers. Engineered for minimal vibration and thermal output, the bits maintain stability even at mid-range RPMs (15,000–25,000). Their geometry avoids pressure concentration, lowering risk of nail plate overheating or micro-trauma. The slim profile allows access to anatomically constrained zones — such as lateral nail margins and proximal fold recesses — supporting thorough yet conservative nail prep and maintenance.
