Sharpening stone (abrasive grinding wheel) for slicers, size 50 × 8 × 6 mm (diameter × thickness × centre hole). Wear part for the built-in sharpener assembly that restores the edge of the circular blade. Compatible with OMAS slicers and equivalent models. The fine/medium grit offers a good balance between metal removal and edge finish, making it well suited to routine edge maintenance. The wheels work as a pair in the sharpener assembly: keep both grits on hand and replace the stone once it is worn or glazed. Check the three dimensions (diameter, thickness, hole) on your machine before purchase: they determine compatibility regardless of brand.
