The Waring CAF18 1/2" slicing disc is designed for use with select food processors, and can be used as either a direct replacement for a worn out disc, or you can add this disc to your collection to increase the versatility of your unit! This disc is excellent for slicing bok choy, broccoli, spinach, pineapple, and more. It's particularly good for making the types of thicker vegetables used in soups and stews.
