Inverted Cone Tungest Carbide Diamond Bits
【Detail Refinement Master】Inverted Cone Diamond Care Bit・Dead Skin Excision Model
"Unique inverted cone flat cutting surface, precisely excising cuticle hangnails and perfectly aligning nail frame lines."
A dry skin refinement tool designed specially for nail technicians pursuing ultimate details and clean, sharp lines. The unique inverted cone body possesses a flat top surface and precise edge angles, providing an excellent localized operational sightline; utilizing the flat cutting surface at the top, it can extremely gently flatten against the edge of the cuticle pocket behind the nail edges to precisely grind off hardened cuticles and tiny hangnails through horizontal shifting, completely replacing cuticle nippers. Featuring selected blue ring diamond emery with uniform particles, it offers extremely precise positioning control, making it the final key to creating the perfect curvature and detailed lines of the nail frame.
Three Core Advantages:
1. Inverted Tapered Level Cutting Surface: The unique reverse tapered design with precise angles at the top edge can easily cut underneath the already propped-up cuticle, performing a sleek physical excision without leaving behind residual burrs.
2. Premium Diamond Sand: Utilizing industrial-grade diamond micro-particles with a medium-fine grit, it possesses excellent abrasive power and wear resistance, which can gently and rapidly buff and grind clean hard skin and cuticle flyaways on the nail edge.
3. Eliminating Burr Formation: Replaces traditional steel nippers with the physical grinding of the drill bit's reverse cutting surface. The resulting trimmed nail edge skin margin is extremely smooth and level, substantially extending the perfect visual state after care.
Recommended Usage Guide:
・Target Areas: Lateral grinding and severing of cuticles that have already been pushed/loosened behind the nail edge, precise smoothing of minor flyaways and localized hangnails on both sides of the nail edge, and spot-targeted leveling of localized minor steps and uneven cuticles on the natural nail surface.
・Recommended Speed: 6,000–10,000 RPM (When used for nail edge dead skin trimming and detailed care, it is recommended to maintain a medium-to-low speed operation to ensure the most delicate grinding efficiency and absolute safety).
Technique Essentials:
1. Stable Lateral Gliding Excision: Utilize the flat top surface or top edge of the inverted taper during operation, maintaining a parallel or slightly adjusted angle with the nail edge skin, gliding smoothly and laterally along the line of the cuticle pocket to mildly grind off dead skin flyaways. Please keep your hand tension relaxed and perform light caressing and sweeping; never press the sharp angle straight down forcefully onto the natural nail surface or sensitive nail walls.
2. Fine skin debris and dust will be generated during prep care grinding; it is recommended to operate in conjunction with a salon dust collector, and confirm that the handpiece chuck is completely locked and closed.
