Expanding Rubber Wheel 90 x 100mm StealthMounts The longer belt means itDesigned to fit on a double keyway mandrel, the rubber expanding drums offer a even level surface for sanding. The advantage of these drums over pneumatic drums are that there is no over or under inflation, which can cause uneven grinding on your material. The drum relies on centrifugal force to hold the sleeve in place, and since it is a solid rubber drum, you get even grinding across the entire surface.
