Cylinder Left-Handed PVD Coated Nail Drill Bits(Rounded top)
【For Left-Hand Users Only】Left-Hand Cylinder Coated Bit・R-Angle Safety Model
"Specially developed for left-handed nail technicians, featuring reverse special teeth, allowing smooth left-hand operation without bouncing."
Tailor-made for professional nail technicians who habitually use their left hand for operation. Breaking the limitation of traditional bits being restricted to the right hand, it adopts an exclusive left-type reverse cutting teeth design. When the grinding machine is switched to reverse (REV) mode, it can perfectly exert ultimate cutting and debris-discharging performance, operating smoothly without biting into the skin or bouncing; the standard large cylinder body provides the maximum contact area with the nail surface, completing nail removal, flattening, and smoothing steps in one go. Combined with the top safety R-angle (curved anti-scratch design), it allows left-hand operations to possess a fearless and extremely high sense of safety.
Three Core Advantages:
1. Exclusive Left-Hand Reverse Tooth Marks: Hard tungsten carbide tooth marks designed specifically for counterclockwise rotation (REV), with friction and cutting power precisely reverse-optimized, thoroughly solving the pain points of slipping and bouncing common with standard drill bits during left-handed operations.
2. High-Efficiency Straight Barrel Body: Features a large flat grinding range and extremely stable stroke, allowing for highly efficient and uniform leveling of nail extension surfaces, trimming of junction steps, or rapid large-area removal of gel building layers.
3. Safe Rounded R-Angle: The micro-barrel rounded protective cut at the tip prevents scratching delicate skin when working deep into back nail edges or side nail grooves, substantially elevating the tolerance rate during left-handed fine operations.
Recommended Usage Guide:
・Target Areas: High-efficiency removal of large-area gel and building layers under left-handed operation, smoothing out step marks after nail tip application, buffing/leveling the surface of nail extensions, and safe micro-adjustments of dead skin around nail edges and nail grooves.
・Recommended Speed: 15,000–20,000 RPM (When used for high-efficiency large-area gel removal or cutting hard gel structures, the speed must be increased to fully unleash the cutting performance of its special left-hand tooth marks).
Technique Essentials:
1. Stable Reverse Gliding: The nail drill machine must be switched to reverse (REV) mode. Lay the flat surface of the straight barrel flat against the gel surface during grinding, and glide smoothly along a single direction comfortable for the left hand. When approaching the back of the nail edge, use the top R-angle to gently sweep along the U-shaped contour; never apply pressure and stay on the same spot of the nail.
2. Before starting the nail drill machine, please be sure to confirm that the handpiece chuck is completely locked and closed.
