- rounding corners of boards (hard soft woods, particle board, MDF, laminates etc)
- smoothing, adjusting and rounding ceramic wall tiles for fitting of tile in awkward spaces

DuraGRIT® Tools are coated with carbide grains that equate to the US Mesh system of measurement.
Therefore a 60 grit DuraGRIT® tool is equivalent in grade to a 60 grit sandpaper product.
European grading is slightly different but very similar.
The good news is, when you start using your DuraGRIT® tool, it remains the same grade from start of the job to the finish of the job, leaving a consistent finish, unlike sandpaper products that wear quickly, degrade in grit grade and leave an inconsistent finish.
