Britney Cylinder Diamond Bit – Medium Grit (3.1 × 8.0mm)

The Britney Cylinder Medium is a professional diamond bit designed for efficient overlay refinement and nail surface preparation. With a flat cylinder head, 3.1mm extra-wide diameter, and 8.0mm working length, it removes product up to 30% faster than standard bits while maintaining precise control.

Its medium diamond coating offers balanced abrasion — ideal for levelling uneven overlays, refining lifted edges, and buffing thicker cuticles during pedicures. Finished with a PVD Gold coating, Britney combines durability with superior performance.
