The rounded cone geometry can also be useful when working around different areas of the nail surface and during correction procedures.
Green Coarse Cross-Cut
The green marking indicates a coarse cut intended for intensive material removal. The large cross-shaped teeth create active cutting edges that help remove dense artificial material efficiently.
The 407401 is listed as a coarse green carbide bit, with the 6 × 14 mm working dimensions and large cross-cut specification confirmed by multiple product listings.
How to Use
Insert the bit into a compatible e-file handpiece and select the rotation speed according to the material and procedure. Work with controlled, continuous movements and moderate pressure. Avoid prolonged contact in one area.
The coarse green cut is intended primarily for dense artificial materials and material reduction, rather than aggressive filing directly on the natural 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.
Sterilization:
Autoclave: Place the cleaned and dried bit into a sterilization pouch and seal it before placing it in the autoclave.
Sterilization cycle: 132°C, 2 bar, 20 minutes.
Dry heat sterilization: Place the cleaned and dried bit into a dry-heat sterilizer.
Sterilization cycle: 180°C, 60 minutes.
