The 2244 Oscillating Drum Sander from JET has an exclusive oscillating feature that helps create the best sanding finish with the least amount of dust. When in the oscillating mode, the sanding drum head oscillates from left to right which lowers heat build-up on the sanding belt, reducing loading and burning. The innovative tool-less parallelism system keeps adjustments simple. The worktable is easily positioned by a turn of the parallelism dial. The Sandsmart conveyer system continuously monitors the load on the drum motor to prevent an overload situation. The mirrored design of the dust hood optimizes dust collection preventing chips and dust from getting between your work-piece and the finish. The JET 2244 Oscillating Drum Sander delivers everything you need for an effortless finish.
