STALEKS PRO EXPERT DUO Diamond Bit — Tapered Cylinder (Truncated Cone), Blue-Red, 2.5 x 8 mm

The STALEKS PRO EXPERT DUO Truncated Cone diamond bit with blue-red band (2.5 mm diameter, 8 mm working part) is a dual-coated instrument of soft-to-medium abrasiveness, crafted for delicate skin processing during e-file manicure and pedicure. The truncated cone shape enables versatile work on both natural and artificial coatings — shaping the free edge of the nail plate and smoothing surfaces with ease. Suitable for both beginner and advanced nail professionals.

This DUO bit is produced using a double-layer diamond coating technique on a medical-grade stainless steel blank. First, medium-fraction diamond particles are applied, then the gaps between them are evenly filled with finer crystals, creating a dense, uniform abrasive surface. The grit is locked in place through a galvanic process where a thin nickel layer securely bonds the diamond particles, resulting in a robust and long-lasting connection.

The dual-coating technology gives the instrument exceptional hardness and wear resistance while maintaining a flawless working surface. The DUO double-layer diamond coating significantly extends the bit's service life, with diamond particles distributed evenly — no bare spots or clumps. This truncated cone bit lifts cuticles, processes lateral folds, removes pterygium, preps nails for extensions, shapes the free edge, and handles length corrections with precision.
