ABSTRACT:
A portable, direct drive abrasive saw for cutting ceramic tile, bricks, masonry blocks, metal, refractory, or other work comprising a base pan of an electrically insulative, synthetic resin material with the pan constituting a coolant reservoir. A frame is secured to the pan and the frame includes a pair of generally parallel, spaced rails extending horizontally of the pan and a saw support fixture. A unitary, direct drive abrasive saw is fixedly mounted from the saw support fixture in a cutting position. The saw includes an electric motor, a rotary abrasive saw blade with the rotary axis of the saw blade being disposed within a plane generally perpendicular to the rails and a drive for directly interconnecting the motor and the saw blade. A table is provided reciprocably mounted on the rails for supporting the work to be cut and the table is movable toward and away from the saw blade from a retracted position in which the table and the work thereon is clear of the saw blade and a cutting position in which the saw blade cuts through the work as the latter is moved past the saw blade. The saw further includes a coolant pump for circulating coolant from within the pan over the saw blade as the work is cut.
