ABSTRACT:
A saw assembly for a floor installer to use in undercutting baseboards, doors, and the like includes an electric motor subassembly having an electric motor and a spindle rotatably powered by the electric motor, a circular blade mounted on the spindle, and a blade guard subassembly. The blade guard assembly includes a moveable component adapted for movement to a retracted position that exposes more than 180 degrees of the circumference of the circular blade in order to facilitate the undercutting of a ninety degree inside corner. One embodiment uses a conventional handheld 11,000 rpm high speed grinder motor assembly with a right angle drive to power a high speed 4-inch blade in place of a grinder wheel. Carrying the undercut saw with a grinder wheel, sanding wheel, and a tile cutting blade adds functionality.
