Looking for a nail drill bit for professional foot care? The Promed sapphire ball bit has a coarse grit and a rounded ball shape for working on skin and callus on the feet. Its natural corundum sapphire surface is intended for the initial, coarser stage of callus work, where a controlled approach across larger areas is required. The 2.35 mm dental-size shank and recommended speed of up to 20,000 rpm support its use in a professional workflow.

• Nail drill bit for skin and callus
• Natural corundum sapphire material
• Rounded ball shape
• Coarse grit
• 2.35 mm shank diameter
• Recommended up to 20,000 rpm
• Suitable for ultrasonic bath cleaning

The ball profile supports even work over larger areas of foot skin and callus. The coarse surface makes this Promed bit suitable for an initial pass before a finer grit is selected for further finishing. This makes it a practical choice for professional foot-care treatments requiring focused work on pronounced callus.

For controlled use, work with light pressure and even movements. Gradual removal in thin layers keeps the treatment approach measured while allowing the professional to monitor the area being worked on. The rounded shape offers a direct working surface for broad sections of skin without changing the intended application of the bit.

Clean the bit thoroughly in an ultrasonic bath after use. This Promed professional nail drill bit is not suitable for autoclaving. Regular ultrasonic cleaning keeps the tool ready for subsequent professional foot-care work and supports an organised treatment routine.

The Promed sapphire ball bit combines a coarse grit, ball shape and 2.35 mm shank for targeted work on skin and callus on the feet. It is a focused addition to a professional selection of nail bits for drill use.
