Cleaning Stone For CBN Wheels & Diamond Stone 400G

This rectangular block of aluminium oxide abrasive (70 x 30 x 20mm) removes the loading that may build up on the surface of your CBN grinding wheel. This simple dressing stick cleans the wheel, exposing the diamond particles, making the wheel cut like new again. The aluminium oxide has no effect on the diamond surface itself, except to restore its free-cutting action.
