DARK nail drill bit Ball 4 mm (Red)

Diamond Ball Bit (Red / Fine Grit)

A professional diamond ball bit designed for hardware and combined manicure and pedicure techniques. It gently lifts and removes the cuticle while smoothing skin around the lateral nail folds and sinuses, making it ideal for both beginners and experienced nail technicians.

Key Features:

• Red Grit (Fine): Suitable for normal, thin, soft, and sensitive skin, as well as treating light roughening, calluses, and final skin polishing;
• Premium, uniformly sprayed diamond coating with pre-sieved particles for consistent geometric shape;
• Strict quality control: the base of each bit is tested for radial runout to ensure precise, vibration-free operation;
• 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: 10,000 – 20,000 RPM (for 30-65W devices);
• Cleaning: Use a stiff plastic brush or an ultrasonic cleaner 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.
