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

The STALEKS PRO EXPERT DUO Truncated Cone diamond bit with blue-green band (2.5 mm diameter, 8 mm working part) is a dual-coated instrument of medium-to-coarse abrasiveness, purpose-built for processing tougher, calloused outer skin. The truncated cone with its medium-coarse grit works effectively on artificial coatings, shapes nails, and smooths cracks during pedicure treatments. Recommended for experienced nail professionals.

This DUO bit is manufactured using a double-layer diamond coating on a medical-grade stainless steel blank. First, coarse-fraction diamond particles are deposited, then the spaces between them are filled with medium-sized crystals, creating a dense and thorough coverage across the entire working zone. The galvanic bonding process applies a thin nickel layer that locks every diamond particle in place for a strong, long-lasting hold.

The dual-coating approach delivers remarkable hardness and resistance to wear while maintaining a smooth, uniform working surface. The DUO double-layer diamond technology significantly extends the bit's usable life by ensuring even grit distribution with no gaps or clustering. This truncated cone bit excels at treating outer skin areas (avoiding the natural nail surface), buffing extended nails, shaping the free edge, correcting nail length, and working with cracks in pedicure settings.
