Belt & Disc Sanders are ideal combination machines for tackling a variety of surfacing and shaping needs on projects. Taking up little space in your shop, these portable sanders can be easy stored away when not in use. Their rotating Discs use easy-to-apply pressure sensitive adhesive backed (PSA) sandpaper, and with their work tables offer great control for touching up board ends, rounding off corners, or sanding small parts. The Belts provide similar sanding functions as the discs, with some additional advantages. The 1” wide belts surface only smaller materials, but their rear support platens can be removed to allow flexing of the belts for working curved and deep areas on projects. The bigger 4” belts run on wide frames and are best for sanding larger board faces and edges. 1” belt and disc tables adjust for sanding angles and have slots for use with miter gauges. The #51-200 is for disc sanding only, where its generous 12” size has countless uses for finishing work. Sanders are wired for use with 3-wire 120V electrical receptacles.
