Two specific tasks: precision cleanup around the cuticle pocket and under-nail debris removal beneath the free edge. Fine-tip diamond bits reach into these detail-heavy areas without filing into healthy tissue.
It's the step that separates a manicure that looks polished from above from one that looks polished from every angle. Under-nail debris and lifted product build up between services and shows in close-up photography — strong reason to add this step to every service.
Lower than larger diamond bits — 5,000 to 8,000 RPM is the safe range. The fine tip shapes generate more heat per unit area than larger bits, so light touch and lower speed protect the surrounding skin.
Yes — diamond is the only bit material safe for direct contact with natural nail and skin. Carbide and ceramic bits are not safe in these detail areas. The fine-tip shapes in this collection are specifically built for cuticle pocket and under-nail work.
2–4 months under daily Pro use. Clean with a brass wire brush after each client to remove residue from the diamond grit, then immerse in Barbicide. Avoid frequent autoclave cycles — they accelerate wear on the diamond coating.
