STALEKS PRO EXPERT Diamond Ball Bit — Red (Fine), 4 mm

For fine, controlled e-file work, the STALEKS PRO EXPERT 4 mm red diamond ball bit is a top-tier choice. This classic ball-shaped attachment is designed for manicure applications — opening lateral folds, processing cuticles, and performing detailed finishing. It can also serve pedicure needs, particularly the removal of deep-set corns.

Available in fine (red) and medium (blue) abrasive levels with a 4 mm head, the maximum recommended speed is 25,000 RPM. Suitable for cuticle care, lateral fold and sinus treatment, corn and crack work, and nail piercing.

Proper aftercare extends the life of every diamond bit. Clean and wash thoroughly after each client session — ideally with an ultrasonic cleaner — then sterilize and disinfect. Store in a sealed container protected from dust and humidity. Every STALEKS instrument is manufactured under ISO 9001:2015 quality protocols, with each batch undergoing detailed inspections of edge sharpness, fastener quality, surface polish, assembly integrity, and durability under repeated use.
