Abstract:
A saw for cutting a rectangular hole for electrical or data outlets in gypsum board. The saw includes a handle, and rectangular frame cutting element that cuts all four sides of a rectangular hole in a single operation. Each cutting surface on the frame typically has several sets of stepped teeth so that the highest tooth in the step engages the board first; then the second highest tooth engages the board after the first tooth has partially cut into the board. This stepped tooth approach provides an effect similar to have started several separate saws independently along each of the four sides of the hole. The handle provides leverage to effectively engage each of these sets of teeth at the same time. The tool is typically worked by moving the handle side to side or up and down in short strokes to move the teeth through the board.
