The fine sapphire surface makes this nail drill bit suited to controlled finishing work on foot skin and callus. Its rounded head follows curved areas for an even result, making it useful after initial callus removal. The ball shape allows the professional to focus on refining the treated area while maintaining a consistent movement. This makes the bit a practical choice for detailed pedicure work where a smooth final finish is required.

With its 2.35 mm shank, the bit fits Promed nail drills equipped with a 2.35 mm chuck. It is recommended for speeds up to 20,000 rpm. Using light pressure and steady movements supports controlled work during foot care treatments. The fine grit is intended for the final refinement stage rather than the initial treatment of pronounced callus.

After use, the Promed bit can be processed in an autoclave at 121–134 °C or cleaned in an ultrasonic bath. These cleaning options allow the tool to be incorporated into the established cleaning routine of a professional salon. The sapphire ball design, fine grit and foot-care application make it a focused addition to a professional selection of efile bits.
