• HALMAI Professional PVD Vacuum-Coated Tungsten Carbide Nail Drill Bits

Made with a high-tungsten carbide material containing approximately 91% tungsten, combined with an approximately 0.8 μm PVD vacuum coating and a full cutting-flute design for efficient removal and improved wear resistance.

Testing shows that product removal efficiency and service life may be increased by up to approximately 2×, depending on the bit type and testing conditions.

With concentricity ≤ 0.025 mm and shank straightness ≤ 0.02 mm, the precision-machined construction helps reduce rotational runout, providing smoother rotation and lower vibration during high-speed use.

• HALMAI Artisan Series Bi-Directional Natural Nail Prep Bit

Made from high-tungsten carbide containing approximately 91% tungsten and finished with an approximately 0.8 μm PVD vacuum coating, this bit is designed to balance precise cutting performance with enhanced wear resistance.

An approximately 0.04 mm cutting texture combined with a bi-directional cutting design allows controlled work on the natural nail surface and around the cuticle area, making it suitable for detailed nail preparation.

With concentricity ≤ 0.025 mm and shank straightness ≤ 0.02 mm, the precision construction helps minimize rotational runout for smoother, more stable, and easier-to-control operation.

• HALMAI Artisan Series 3-Piece Diamond Nail Prep Bit Set & Round Top Barrel Diamond Nail Prep Bit

Built with a 304 stainless steel base and 360° full-coverage diamond coating, these bits are designed to provide consistent abrasion and stable rotation during detailed nail preparation.

With concentricity ≤ 0.025 mm, the precision construction helps deliver smoother and more even performance.

The 3-piece prep set is designed for different detailing tasks, including cleaning the cuticle pocket and sidewalls, refining the natural nail surface, and removing small pieces of dry skin or hangnails.

The Round Top Barrel Bit is ideal for smoothing cuticle edges and refining the surrounding nail area with greater control.

• HALMAI Artisan Series Pro 3.1 mm Mini Sanding Band Mandrel Set

Made with a 304 stainless steel mandrel and a compact 3.1 mm mini design, this set supports both forward and reverse rotation for flexible work in narrow and hard-to-reach areas.

With concentricity ≤ 0.025 mm and mandrel straightness ≤ 0.02 mm, the precision-machined structure helps reduce rotational runout and supports smoother, more stable operation.

Ideal for natural nail preparation, underside cleaning, sidewall refining, and detailed work around the nail edges.

**Material composition, coating thickness, cutting texture, concentricity, and shank or mandrel straightness specifications apply only to the corresponding product models indicated above and are based on HALMAI-provided inspection or laboratory testing data. Comparative performance should be evaluated under defined testing conditions against appropriate reference samples. Actual results may vary depending on nail drill performance, RPM, operating technique, enhancement material, and working environment.

*Different bit shapes are designed for different stages of the nail service, allowing more precise preparation, flexible detailing, and efficient product removal. Precision-machined shanks and working surfaces help provide nail professionals with a smoother and more controlled operating experience.
