The coarse grit is suited to more substantial work on thicker callus and firm nail edges. Its classic cone profile can be used across larger areas as well as on specific edges and corners. These nail bits for drill use offer a focused form for professional treatments involving skin, callus and the natural nail plate.

The 2.35 mm shank is designed for Promed nail drill devices with a 2.35 mm collet. Use the bit at a recommended speed of up to 20,000 rpm. Apply light pressure during treatment and lift the bit briefly from the surface if heat develops. This supports controlled work during initial, coarser stages of a pedicure or nail care treatment.

After each use, the Promed bit can be cleaned in an ultrasonic bath. It can also be autoclaved at 121–134 °C. These cleaning methods support regular salon tool care. The coarse sapphire grit and cone shape make this professional nail drill bit suitable for working on persistent callus and shaping firm nail edges before moving on to finer work.
