Nail drill bit with a conical shape. As the bottom part is wider and narrows as it goes up, it is ideal for material removal, nail shaping, or artificial nail formation.

The bit has an indication in red color, which determines its coarseness. The rougher the surface, the more material it removes.
The colors on the bits are translated as follows:
• Orange (Very coarse)
• Black (Coarse)
• Green (Medium coarse)
• Blue (Medium)
• Red (Slightly coarse)
• Yellow (Very slightly coarse)
• Purple (Slightly coarse)
