Coarse-grit emery grinding wheel for sharpening meat slicer blades. The stone mounts on the sharpener assembly (either removable or built-in) and, acting on the edge of the rotating blade, restores its cutting ability by removing material decisively. The coarse grit performs the actual sharpening; it is usually paired with a second fine-grit wheel, which finishes the job by removing the burr from the edge and refining the cutting edge.

• Diameter: 45 mm
• Thickness: 8 mm
• Centre hole: 10 mm
• Grit: coarse (sharpening/deburring)

Always check that all three dimensions (Ø 45 mm, thickness 8 mm, hole 10 mm) match the wheel currently fitted on your machine: the key factor for interchangeability is precisely the diameter × thickness × hole combination. When to replace it: the wheel should be changed when it is worn, glazed or chipped, when the blade no longer sharpens properly, or when the remaining diameter no longer allows regular contact with the edge. For optimal sharpening, keep the wheel free of grinding residue.
