DARK Ball 4 mm (Blue)

Diamond Ball Bit (Blue / Medium Grit)

A professional diamond ball bit designed for hardware and combined manicure and pedicure techniques. It effectively lifts and removes the cuticle while smoothing rough skin around the lateral nail folds and sinuses.

Key Features:

• Blue Grit (Medium): Ideal for treating rough or dry skin, calluses, cracks, and final skin polishing;
• Premium, uniformly sprayed diamond coating with pre-sieved particles for consistent geometric shape;
• Strict quality control: each bit is microscopically inspected and tested for radial runout;
• Durable and rust-resistant: withstands moisture, steam, and high temperatures;
• Fully compatible with liquid disinfection, dry-heat sterilization, and autoclaving.

Recommendations for Use:

• Optimal Speed: 5,000 – 15,000 RPM (for 30-65W devices);
• Cleaning: Use a stiff plastic brush rather than a metal brush to preserve the diamond coating;
• Sterilization Prep: Thoroughly dry the bit (using a dry-heat drying mode, UV cabinet, or air-drying for at least 6 hours) after liquid disinfection and before high-temperature sterilization.
