The STALEKS PRO EXPERT DUO blue-green diamond flame bit (2.1 mm diameter, 8 mm working length) is a medium-coarse abrasiveness attachment featuring dual-layer diamond coating, engineered for working on external hardened skin. The sharp flame shape at this grit level reaches tight areas with ease, files delaminations, shapes the free edge of overgrown nail plates, and buffs artificial coating surfaces. Best suited for experienced nail technicians.
Crafted using a dual-deposition technique, coarse diamond grains are applied first to a medical-grade stainless steel blank, then the spaces between them are uniformly filled with medium crystals, achieving dense, complete coverage. An electroplating process bonds the diamond layers with a thin nickel coat, producing a connection of remarkable strength and longevity.
The dual-coating method gives the working surface exceptional hardness and wear resistance with no surface irregularities. The DUO flame bit lasts significantly longer thanks to its even, gap-free double diamond layer. With its medium-coarse abrasive and dual coating, this flame bit handles external skin treatment (avoiding the natural nail surface), buffs artificial extensions, files delaminations, and shapes the free edge — all while minimizing the risk of client discomfort.
