Abstract: A plunge cutting device for use with a portable drill, drill press, or other rotary drive source which is capable of cutting irregularly shaped openings or workpieces in a single operation. A drive chain, belt, or other means carries a plurality of cutting teeth along a path defined by a series of chain guides. A lower plate, adjacent the surface being cut serves as a finer resolution guide for the cutting teeth to define their cutting path. The configuration and orientation of the cutting teeth causes them to push inward against the edge of the plate so that they follow its shape closely. A preferred shield encloses the teeth, chain, and drive mechanism for safety and to serve as a vacuum shroud for dust collection. The shield may also act as a guide, holding the teeth in position prior to the start of the cutting operation.
