A specialist diamond bit engineered for controlled callus reduction and skin refinement in pedicure services.

The Blueberry Medium is a large diamond  bulb-like barrel bit designed specifically for pedicure work, making it the go-to tool for reducing calluses and working on hardened skin safely through exfoliation - not cutting.

Its larger surface area allows you to cover more skin efficiently, while maintaining a controlled, gentle approach - making it ideal for technicians who want effective results without compromising client safety or comfort.

This makes it ideal for:

• Callus reduction and hardened skin

• Pedicure services requiring controlled exfoliation

• Technicians transitioning away from blades or paddles

This is a pedicure refinement bit, designed for safe, professional skin work through exfoliation & reduction - not removal.

HOW TO USE

Use during the pedicure callus reduction stage

Work at 15,000 RPM

Use light pressure—never force the bit

Glide across callused areas evenly going against the grain of the skin & then with the grain 

Always leave a small layer of hardened skin (approx. 10%) for safety

Use alongside a callus remover product for best results & reduced friction 

If callus remover isn't required then you can use a spray sanitiser to avoid warmth
