ABSTRACT:
A portable deglazing tool for removing glazing compound from window frames while simultaneously refinishing all surfaces preparatory to facilitate reglazing and glass replacement if required. The deglazing is accomplished by a fluted cutting bit with a flat lower end driven from an electric motor at a speed of at least 20,000 r.p.m. and the bit operates through aligned apertures in a base and sub-base with indexing on the tool to set the bit to operate at the location and the depth of the ledge of the window frame.
