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.
Claims4
A saw assembly, comprising:
- an electric motor subassembly, the electric motor subassembly having an electric motor adapted to produce rotational movement about a first axis of rotation and a spindle rotatably powered by the electric motor for rotation about a second axis of rotation that is perpendicular to the first axis of rotation;
- a circular blade mounted on the spindle, the blade having teeth that extend to an outer circumference of the circular blade;
- and
- a blade guard subassembly mounted on the electric motor subassembly, the blade guard subassembly including a fixed component intersecting a plane formed by said first and second axes of rotation and a movable component that combine operatively to provide a protective cover over at least a portion of the circumference of the circular blade, and said movable component adapted for movement by a user to a retracted position of the movable component that exposes more than 180.degree. of the outer circumference of the circular blade.
