A high-coverage diamond ball bit engineered for efficient cuticle refinement and controlled removal of non-living tissue.

The Big Ball Fine is designed for technicians who want maximum efficiency without compromising control. Its larger ball shape allows you to remove dead protein and cuticle quickly across wider areas, making it a powerful upgrade from standard ball bits.

Ideal for:

• Faster prep covering a larger area

• Clients with less visible cuticle or dead protein

• Replacing cuticle nippers with confidence

This is a Step 2 (and optional Step 3) prep bit, designed for efficient, high-coverage refinement.
