ABSTRACT:
Cutting shaped holes is accomplished by the device by including a foot plate on the part to be cut and a cutting tool which is driven around the foot plate in accordance with the hole shape selected. A template determines size and shape of the hole, and a cutting tool movable on a rotating arm follows the template. The template also controls the position of the cutting tool with respect to the direction of cut so that efficient cutting is achieved.
