Three Core Advantages:

1. Giant Straight Barrel Round Head: The extra-large grinding contact surface offers a stable and powerful stroke, providing extremely high efficiency for large-area grinding; the rounded design at the top smoothly rolls along the contours of toes and nail edges, preventing sharp angles from poking and injuring the skin.
2. X-Shaped Crisscross Debris-Evacuation Grooves: Developed specifically for handling large amounts of hard skin and thick nail debris, dust and debris are instantly discharged along the grooves during grinding, preventing them from clogging the drill bit surface, while significantly slowing down heat accumulation to avoid burning sensations.
3. High-Hardness Diamond Micro-Particles: Selected premium wear-resistant diamond sand material with uniform particles and extremely strong grip can easily level and smooth even the hardest hyperkeratosis or aging nails effortlessly.

Recommended Usage Guide:
・Target Areas: Large-area grinding of old, waste thick calluses and hard skin on the feet, thinning and leveling the surface of hyperplastic nails and thick nails (such as toenail fungus), and meticulously smoothing out stubborn hard calluses on the sides of toes.
・Recommended Speed: 8,000–15,000 RPM (When used for foot hard skin and thick nail grinding, a medium-to-high speed must be maintained to fully release the abrasive performance of the diamond particles; please make moderate micro-adjustments based on the client's skin sensitivity and structure hardness).

Technique Essentials:

1. Stable Large-Area Gliding: Lay the flat surface of the large straight barrel flat against the surface of thick calluses or thick nails during operation, gliding stably along a single direction; never apply excessive pressure or stay on the same spot. When treating nail edges, use the curvature of the round head to gently sweep across.
2. Because the amount of dust generated during the grinding of foot calluses and problem nails is extremely large, it is strongly recommended to operate in conjunction with a powerful foot dust collector, and please confirm that the handpiece chuck is completely locked and closed.
