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.

A portable, direct drive abrasive saw for cutting ceramic tile, bricks, masonry blocks, metal, refractory material, or other similar work comprising a base pan constituting a coolant reservoir, a frame secured to said pan, said frame including a pair of generally parallel, spaced rails extending horizontally of the pan when said saw is in its normal operating position, a saw support, a unitary, direct drive abrasive saw mounted on said saw support in a cutting position, said saw including an electric motor haing an axis of rotation, a rotary abrasive saw blade with the rotary axis of said saw blade being coaxial with the rotary axis of said motor, means for directly interconnecting said motor to said blade for rotatably driving said blade, a table reciprocably mounted on said rails supporting said work to be cut and being movable in a generally horizontal direction toward and away from said saw blade from a retracted position in which said table and the work thereon is clear of said saw blade and a cutting position in which said saw blade cuts through said work as the latter is moved past said saw blade, and a coolant pump for circulating coolant from within said base pan to said saw blade as the latter cuts through the work, said saw support including at least one horizontal frame member extending transversely of said rails above the level thereof at one end of said frame, said at least one horizontal frame member being rigidly secured relative to said frame, and means cantilevered from said at least horizontal frame member and extending from one end of the frame back toward the other end thereof in a direction generally parallel to said rails for mounting said unitary direct drive abrasive saw, said direct drive saw including said motor and said abrasive saw blade being pivotably mounted on the free end of said cantilevered support means for rotation about a second axis generally parallel to and eccentrically offset from the rotary axis of said saw blade thereby to selectively permit the raising and lowering of said saw blade relative to said table, and means for locking said saw at a desired height.
