Foredom’s disc mandrels come with different head diameters and shank sizes. When making your selection be sure that the head diameter of the mandrel matches the diameter of the disc you intend to mount. For 1″ and smaller diameter discs, also confirm that the shank size of your mandrel is the same as your handpiece collet or within the capacity of you handpiece chuck when using a flex shaft machine. For larger 2″ and 3″ diameter accessories, confirm that the shank size of your mandrel is the same as the collet in your collet holder when using a M.BL Lathe. The proper fit will help to insure your safety and keep the accessory running true.
