Cylinder Smooth Top PVD Coated Nail Drill Bits(Rounded top)
【Exquisite Prep Care】Ultra-Fine Cylinder Anti-Damage Bit・R-Angle Safety Model
"Micro cylinder body, gently trimming and smoothing the connection between hard skin and dry skin around nail edges."
A gentle tool developed specially for high-end salon Russian prep and exquisite nail edge care. The ultra-micro, ultra-fine cylinder design provides an unobstructed, ultra-clear sightline, allowing it to extremely delicately flatten against the nail grooves on both sides and the back of the nail edges to precisely grind away stubborn hard skin and dead keratin accumulated on both sides; the unique R-angle (curved safety design) at the top can perfectly fit the tiny U-shaped contour of the nail edges, providing foolproof anti-scratch protection during deep cleaning, leaving the nail edges after prep care with clean, rounded, and ultimately healing perfect lines.
Three Core Advantages:
1. Safe Rounded R-Angle: The micro-barrel rounded protective design at the tip prevents scratching the skin or creating red marks when working deep into fragile nail edges and the seam of natural nails.
2. Ultra-Micro Straight Barrel Body: The extremely fine barrel cutting surface offers excellent line-of-sight visibility, capable of precisely cutting into extremely narrow side nail grooves to stably grind hard skin, making it the premier care choice to replace traditional cuticle nippers and elevate salon quality.
3. Wear-Resistant Fine Tungsten Carbide Teeth: Utilizes high-specification hard tungsten carbide with fine, dense tooth marks, providing a gentle cut without pulling, which can rapidly sweep away dead skin cells, while being easy to clean/disinfect and having a long lifespan.
Recommended Usage Guide:
・Target Areas: Buffing and trimming of dead skin and stubborn hard skin in the nail grooves on both sides, micro-adjustments of dry skin and cleanup of seams behind the nail edge, and meticulous trimming of uneven cuticles on the margins of the nail surface.
・Recommended Speed: 6,000–10,000 RPM (When used for nail edge hard skin care and grinding dead skin, it is recommended to maintain a medium-to-low speed operation to ensure gentleness and absolute safety).
Technique Essentials:
1. Lay Flat and Lightly Caress to Grind: Lay the flat surface of the micro straight barrel flat against the hard skin of the nail walls on both sides and sweep along the direction during operation. When approaching the back of the nail edge, slightly adjust the angle of the drill bit and use the top R-angle to gently sweep clean along the U-shaped contour. Due to its extremely fine body shape, please keep your hand tension relaxed and glide gently; never apply pressure and stay on the natural nail or the same spot of the skin.
2. Before starting the nail drill machine, please be sure to confirm that the handpiece chuck is completely locked and closed.
