The HALMAI 5-in-1 Professional Tungsten Carbide Nail Drill Bit is made with 91% tungsten carbide and combines a PVD vacuum coating with 5-axis precision manufacturing to deliver powerful cutting performance, improved wear resistance, reduced vibration, and greater stability during professional use. Precision control of the tooth geometry, concentricity, and shank straightness helps maintain smooth, consistent performance even at higher speeds, giving professional nail technicians greater control throughout the service.
The unique 5-in-1 cutting design allows different sections and working angles of the bit to handle multiple tasks, including product removal, shaping, detail work, surface refinement, and structural finishing. One bit can cover several steps of the service, helping reduce frequent bit changes and creating a faster, more continuous workflow.
The optimized Full Cutting Edge design allows more of the cutting surface to actively engage with the material, improving removal efficiency when working on gel polish, builder gel, nail enhancements, and other artificial nail products. The tungsten carbide body, combined with the PVD vacuum coating, enhances wear resistance and chip resistance while helping reduce product buildup for easier cleaning and more consistent long-term performance.
Built with high-precision manufacturing, the bit offers excellent concentricity and shank straightness to help minimize runout and vibration during high-speed rotation. This creates smoother transitions between different working areas and gives nail technicians greater stability and control throughout removal, shaping, and finishing.
Designed for frequent professional salon use, the HALMAI 5-in-1 Bit delivers a balanced combination of versatility, cutting efficiency, stability, precision, and long-term durability.
- Made with 91% tungsten carbide for strong cutting performance and excellent wear resistance.
- 5-in-1 cutting design supports multiple removal, shaping, and finishing tasks with a single bit.
- Helps reduce frequent bit changes for a more efficient professional workflow.
- Up to 2× higher material removal efficiency*.
- Up to 2× longer service life*, helping maintain consistent sharpness during extended use.
- PVD vacuum coating improves wear resistance and chip resistance while helping reduce product buildup for easier cleaning.
- Atomic-Level Bonding coating technology, approximately 0.8 μm thick*, designed to improve coating adhesion and surface stability.
- Full Cutting Edge design allows more of the cutting teeth to actively engage with the material for more efficient removal.
- High concentricity ≤ 0.025 mm*, helping reduce runout and vibration at high speeds.
- Shank straightness ≤ 0.02 mm*, supporting a more precise fit inside the handpiece.
- 5-axis precision manufacturing creates a smoother and more consistent cutting path.
- Optimized for professional high-speed use to deliver lower vibration, smoother transitions, and greater cutting stability.
*Based on HALMAI laboratory testing. Material removal efficiency, service life, coating performance, and rotational stability should be evaluated under defined test conditions against a specified comparison sample. Actual performance may vary depending on the nail drill machine, RPM, operating technique, enhancement material, and working environment.
Remove nail dust and product residue from the bit after each use.
For routine cleaning, briefly soak the bit in a compatible cleaning solution, then gently clean along the cutting grooves with an appropriate bit-cleaning brush. Rinse with clean water or wipe with alcohol as appropriate, then allow the bit to air-dry completely.
Avoid dropping the bit, striking it against hard surfaces, or scraping the cutting area with hard or sharp objects, as this may damage the cutting teeth, PVD coating, or overall precision of the bit.
For professional salon use, follow all applicable local hygiene, cleaning, and disinfection requirements, as well as the instructions for the cleaning or disinfection products being used.
FAQ
The bit features multiple working zones along its cutting surface, allowing you to handle different stages of removal and refining with one bit. This helps reduce frequent bit changes and makes the workflow more efficient.
C – Coarse is ideal for faster removal of thicker product layers such as hard gel and extensions.
M – Medium is better suited for regular gel, builder gel, and medium-thickness product layers.
The 5-in-1 Bit is suitable for removing gel polish, builder gel, hard gel, extensions, and other enhancement products, depending on the grit selected.
