This Estella blade is a direct replacement for the one that came standard on your Estella meat slicer. It is compatible with SLM12 meat slicers, and it has a razor sharp stainless steel construction to provide precise cuts. Keeping a sharp blade on your machine ensures that you can easily and cleanly cut through deli meats and cheeses. A dull blade will not only slow down production, but it will cause messy, uneven cuts and waste product. If your original blade is worn out or damaged, replace it promptly to ensure efficient operation of your meat slicer.
