ABSTRACT:
A tile cutting apparatus includes a unit base for holding a tile and guide rods above and running parallel to the base. The guide rods carry a scoring/breaking assembly along a scoring and breaking path. The base includes, on its upper surface, a breaker spline inserted therein and extending along the scoring path. The base's upper surface also includes resilient pads supporting stainless steel rest plates on both sides of the breaker spline. The spline is oriented at a slight angle with respect to the surface of the rest plates to facilitate breaking. The scoring/breaking assembly includes a spring for applying constant pressure to a cutting wheel throughout the scoring operation. The scoring/breaking assembly is constructed such that a single handle allows the user to engage and disengage the cutting wheel, score the tile while maintaining a constant scoring pressure and break the tile. The apparatus includes a molded cover and base that minimize excess assembly and parts.
