A supporting roller platform fabricated from a rigid, durable sheet material such as steel or the like configured to receive in cooperating nesting engagement the skid plate of a power cutting tool such as a rotary saw is disclosed. The roller platform is formed with a flat base and a pair of opposing upstanding side walls or tabs formed from outer lateral portions of the base for supporting a plurality of shaft-mounted wheels. An elongated slot is provided in an axially offset, lengthwise direction of the base for receiving a cutting blade of the power tool therethrough as it is extended toward a working, cutting position after being projected through an overlapping axially offset, lengthwise opening provided in the skid plate. The elongated slot is sized and shaped to fully accommodate the cutting blade at any extended position thereof, as well as providing additional space as necessary to allow for airflow and debris removal from the workpiece during operation. Also contemplated by the present invention are alternative configurations of the blade slot, which may be standardized in width, length, and relative lateral position to accommodate the opening of a skid plate, and hence cutting blade extension and operation of commercially available rotary power saws or even of other power tools.
