Medium Cone PVD Coated Nail Drill Bits(Rounded top)
【All-Round Prep】Medium Cone Coated Bit・R-Angle Safety Model
"Golden ratio medium cone, balancing highly efficient large-area grinding with flexible dead-corner trimming."
A golden, versatile model specially designed for nail technicians looking for an all-round hand-feel. The just-right medium cone body possesses excellent stability when lowering the bit for rapid, large-area etching, while also flexibly changing angles to cut into the perimeter around the nail edges—handling a variety of nail shapes with a single bit. The unique R-angle (curved safety design) at the top can perfectly fit the skin edges, which, paired with the premium heat dissipation performance of the gold tech coating, provides a smooth, gentle, and zero-dead-corner high-texture operation experience.
Three Core Advantages:
1. Safe Rounded R-Angle: The micro-tapered rounded design at the tip can effectively prevent accidental skin scratches when going deep into the nail grooves on both sides and behind the nail edges.
2. Golden Ratio Medium Taper: The body size is moderate without feeling bulky, balancing both the "high efficiency" of large-area buffing and the "flexibility" of localized detail processing, making it the most frequently used style in salons.
3. Tech Coating: A special wear-resistant coating layer can significantly reduce the frictional heat generated during high-frequency operations, providing clients with an ultimate sense of security and comfort.
Recommended Usage Guide:
・Target Areas: Large-area buffing and etching for standard and various nail types, micro-adjustments and trimming of dead skin around nail edges and nail grooves, smoothing out junction steps after nail extensions or nail tip application, and localized residual gel cleanup.
・Recommended Speed: 4,000–6,000 RPM (Please maintain a low speed when etching natural nails; the speed can be moderately adjusted to 8,000 RPM when trimming steps or localized residual gel).
Technique Essentials:
1. Gentle and Fluid Stroke: Utilize the bevel of the medium taper to lay flat against the nail surface and glide smoothly along the direction. When moving to the dead corners of the nail edge, smoothly sweep across following the curvature of the R-angle. This model offers an excellent hand-feel; please maintain a consistent, gentle pressure, and never apply pressure and stay on the same spot of the natural nail.
2. Before starting the nail drill machine, please be sure to confirm that the handpiece chuck is completely locked and closed.
