Sharpening stone (abrasive grinding wheel) for meat slicers, dimensions 45 × 8 × 6 mm (diameter × thickness × centre hole). It is the wear part of the built-in sharpener assembly: mounted on the shaft, it restores the edge of the circular blade with every sharpening pass. Compatible with Sirman slicers (ref. AVA410 / 19300207) and equivalent models:

• Agata 250/275/300/330/350
• Gemma 300
• Mainz 300
• Opale 300
• Quarzo 250/275/300
• Topaz 275
• VAS 250/275/300 · VCO 250/275/300 · VCS 300

The fine grit finishes the cutting edge and refreshes it: it is used in the second stage, after the coarse-grit wheel, to obtain a clean cut with no burrs. The two wheels work as a pair in the sharpener assembly: for correct sharpening it is advisable to have both grits and to replace the stone when it is worn or glazed. Before purchasing, check the three dimensions (diameter, thickness and centre hole) on your machine: these are the measurements that determine compatibility regardless of the slicer brand.
