The 3-Way Flexi-File comes with three grades of Micro Abrasive which allows the user to work up to a very smooth finish.
One side of the file has two Micro Abrasive grades on it. The other side is used for the finishing.
The file is designed to build up to the final finish of a piece.
The 3-Way Flexi File should be used in this order:
- Roughest: Pink: 2400
- Medium: White: 4000
- Smoothest: Grey: 12000
If more material needs to be removed, then a 2-Way Flexi-File can be used first for the faster removal of material.
