Three Core Advantages:

1. Precise Spot-Targeted Spherical Shape: Designed specifically for localized deep cleanup, it can perfectly penetrate deep into the narrow nail grooves on both sides of ingrown nails (onychocryptosis) and hyperplastic cuticles underneath the nail, performing precise spot-targeted decompression and debridement without injuring the nail walls.
2. Hollowed Crisscross Debris-Evacuation Grooves: The special vertical and horizontal cutting pattern with large pitch offers maximum debris-evacuation space, effectively handling the large amounts of thick cuticles and nail debris on the feet. Continuous operation will not cause clogging or easily generate frictional heat.
3. Hard Tungsten Carbide Long Lifespan: Compared to standard sanding bands or diamond drill bits, hard tungsten carbide possesses overwhelming efficiency when dealing with extremely hard problem thick nails (such as toenail fungus), while being high-temperature resistant, easy to clean/disinfect, and having an extremely long lifespan.

Recommended Usage Guide:
・Target Areas: Deep cleanup and decompression of side nail grooves on both sides of ingrown nails (onychocryptosis), localized spot-targeted excavation and trimming of toenail fungus and thickened problem nails, and spot-targeted micro-carving of foot corn cores and localized deep hard calluses.
・Recommended Speed: 8,000–12,000 RPM (Please maintain a medium speed when performing localized fine debridement or excavating hard nails to precisely control the stroke pressure and depth, ensuring absolute safety).

Technique Essentials:

1. Rounded Rolling Spot Buffing: Utilize the curved surface of the sphere during operation, adopting a gentle rolling and tapping method to progressively grind the hyperplastic nails or hard calluses that need cleaning; never press the sphere straight down forcefully onto natural nails or soft tissues. Due to its extremely powerful tungsten carbide cutting force and precise shape, please keep your hand tension relaxed and advance with a "small amounts, multiple times" approach.
2. When performing grinding on problem nails or foot calluses, the amount of dust generated is relatively large. It is strongly recommended to operate in conjunction with a powerful foot dust collector, and confirm that the handpiece chuck is completely locked and closed.
