Expanding Drum with Aluminum Hub, 101.6mm x 25.4 mm

True-running with no wobble or bounce, this high-quality drum delivers better control of your sanding process. Change belts in seconds for lapidary or metalworking tasks such as sprue removal and contour sanding. The drum expands as the wheel rotates to hold the sanding belt firmly in place. The slightly harder-durometer rubber reduces cupping. Features a precision-machined aluminum hub.
