Diamond files are abrasive tools used for shaping and finishing hard materials such as metal, glass, and ceramics. They are graded according to their coarseness, which determines the level of surface finish they can achieve.
They come in grit grades of 120 (coarse), 300 (medium), 400 (fine), 600 (extra fine) and 1200 (super fine).
The four main grades of diamond files are:
- Coarse: These files have the largest diamond particles and are used for rapid material removal and shaping.
- Medium: These files have smaller diamond particles and produce a finer finish than coarse files.
- Fine: These files have even smaller diamond particles and are used for finishing and polishing.
- Extra fine: These files have the smallest diamond particles and are used for achieving a very smooth and polished finish.
It is important to select the appropriate grade of diamond file for the task at hand to achieve the desired result.
