Green Coarse Cross-Cut
The green marking indicates a coarse cut. The cross-shaped teeth are designed for active cutting and material removal. Because of the coarse cut, use controlled movements and appropriate speed when working on the natural nail to avoid excessive reduction of the nail plate.
How to Use
Insert the bit into a compatible e-file handpiece and select a suitable speed for the procedure. Work with light pressure and controlled movements, keeping the bit moving continuously.
When working on the natural nail, use the coarse bit only where its cutting action is appropriate and avoid excessive filing of the nail plate.
Disinfection & Sterilization
Disinfection:
- After use, place the carbide bit into a suitable disinfectant solution. The concentration and exposure time should follow the instructions of the selected disinfectant.
- Clean the working surface from product residue and filings using a nylon or brass bur-cleaning brush.
- For more effective cleaning, the use of an ultrasonic cleaner is recommended.
- Rinse the bit under running water, followed by distilled water.
- Remove excess water with a clean, dry towel.
