STALEKS PRO EXPERT Diamond Bit — Olive Shape, Blue (Medium), 2.5 x 5 mm

The STALEKS PRO EXPERT Olive diamond bit with blue band (2.5 mm diameter, 5 mm working part) is a medium-abrasive instrument with diamond coating, engineered for careful and effective skin treatment. The olive shape is exceptionally versatile — it processes cuticles, lateral nail folds, and calluses without risking injury to the surrounding skin. Equally well suited for entry-level and professional nail technicians.

This bit is crafted by depositing medium-fraction diamond grit onto a medical-grade stainless steel blank. The diamond particles are distributed evenly and densely across the entire working surface, with no gaps or clustering. A galvanic process secures the grit using a thin layer of nickel, bonding the diamond particles firmly and ensuring long-lasting durability.

The advanced coating technology provides excellent hardness and wear resistance while keeping the working surface perfectly smooth and consistent. High-quality diamond grit extends the bit's lifespan and ensures the center of rotation stays true, even during high-speed use. The olive bit lifts and removes cuticles, smooths lateral folds and nail grooves, and in pedicure work, addresses cracks and calluses. Note that medium-grit bits are best kept away from natural nail surfaces. Maximum recommended speed for diamond bits is up to 30,000 RPM.
