STALEKS PRO EXPERT Diamond Ball Bit — Blue (Medium), 4 mm

The ball shape remains the most popular choice among e-file bit profiles, and the STALEKS PRO EXPERT 4 mm blue diamond ball bit is a prime example of why. Built for manicure work, it handles lateral fold opening and cuticle processing with ease. It is also suitable for pedicure applications, including the removal of deep-seated corns.

Offered in fine (red) and medium (blue) abrasive grades with a 4 mm diameter, this versatile bit operates safely at speeds up to 25,000 RPM. Its wide range of uses includes cuticle treatment, lateral fold and sinus work, corn and crack processing, and nail piercing.

To preserve the bit's cutting quality, ensure thorough cleaning after each client — ultrasonic washing followed by sterilization and disinfection is highly recommended. Always store diamond attachments in a proper container, away from airborne dust and moisture. STALEKS production facilities adhere to ISO 9001:2015 quality control standards, subjecting every instrument to rigorous multi-stage testing that covers edge sharpness, hardware integrity, polish quality, overall assembly, and endurance across many uses.
