This metal meat grinder attachment connects to the power hub of KitchenAid stand mixers, so you do not need a separate grinder. It has a sturdy aluminum alloy body, stainless steel blades and grinding plates, and a large stainless steel food tray. Precision parts process up to 2 pounds of meat per minute for burgers, meatballs, and chili, and it also grinds vegetables, fruit, hard cheeses, and breadcrumbs. Three sausage stuffer tubes make everything from breakfast links to bratwurst. Every part detaches quickly for cleaning, and hand washing is recommended. The silver set includes the grinder body, two grinding blades, four grinding plates, a sausage stuffing plate, three sausage tubes, a food pusher, and a cleaning brush.
