Cuticle work and natural nail prep — clearing pterygium and dead tissue, opening the cuticle pocket, exfoliating lifted cuticle, and smoothing the nail surface before gel or acrylic application. The Russian dry manicure technique is built entirely on diamond prep bits.
Diamond is the only bit material safe for direct contact with natural nail and skin. Carbide and ceramic are designed for cured product (acrylic, gel) and will damage nail plate or skin on contact. Diamond grinds rather than cuts, which is gentler and safer for the prep step.
A dry, e-file-driven cuticle method using diamond bits to clear cuticle tissue without water soaking. Three core bits: flame (cuticle pocket), ball (gentle exfoliation), cylinder (general refining). Produces a gap-free finish that gives 3–4 weeks gel retention or longer.
Lower than removal — 5,000 to 10,000 RPM is the safe range for cuticle work. Diamond bits generate heat at high RPM even though they're safe-material. Light touch and lower speed protect the nail bed and the surrounding skin.
2–4 months under daily Pro use. Clean with a brass wire brush after each client to remove product debris from the diamond grit, then immerse in Barbicide. Autoclave is possible but accelerates wear on the diamond coating.
