Abstract: A grinding disc holder for holding and dispensing paper backed abrasive grinding discs. The grinding disc holder includes a base plate and a top plate spaced above the base plate. A spaced apart pair of support rods are extended between the base plate and the top plate. A slide bar is extended between the base plate and the top plate. A clamp plate is interposed between the base plate and the top plate. The clamp plate is positioned between the support rods and the slide bar. A jaw assembly is slidably mounted on the slide bar to permit sliding of the jaw assembly along the slide bar between the base plate and the top plate. The jaw assembly has a sub-assembly for releasably holding the jaw assembly in a fixed positioned on the slide bar. The jaw assembly also has a jaw portion coupled to the clamp plate such that sliding of the jaw assembly along the slide bar in turn moves the clamp plate between the base plate and the top plate.
