The KB Rounded Skin Refining Bit is designed for safe, controlled exfoliation of the surrounding skin - perfect for both fingernails and toenails. Its slim barrel shape allows you to work close to the nail folds without touching the nail plate, giving you precise, gentle refinement exactly where you need it.
Available in Medium and Fine grit, and in Small or Large sizes, this bit is ideal for smoothing, exfoliating, and refining dry, hard skin around the nail and especially effective on toenails where skin tends to be thicker.
Use at 7,000–10,000 RPM for comfortable, controlled performance.
