How to choose the right nail drill bit for each application

Bit materials **Carbide**: removal of artificial material, high efficiency. **Diamond**: work on the natural nail and cuticle. **Ceramic**: low heat, ideal for sensitive areas.

Grit - Coarse: fast bulk removal - Medium: shaping - Fine: finishing and smoothing

Speeds Start low (5,000-10,000 rpm) around the cuticle and increase gradually. Never hold the bit static on one spot.
