A guide assembly is provided with a pair of spaced and parallel guides and includes a carriage mounted on rollers between the guides for longitudinal movement therealong. The carriage can be clamped in position or limited in movement along the guides by means of a pair of slide guides which can be detachably clamped to the guide assembly. A sabre saw is detachably secured to the carriage and the guide assembly is clamped to the work-piece to be cut whereupon the sabre saw and the carriage is pushed along the guide assembly making a straight cut or a bevelled cut in the work-piece, depending upon the setting of the sabre saw assembly. A center pivot bearing assembly is also mounted upon the guide assembly and includes an adjustable work-piece engaging screw engaging the work-piece and acting as a center pivot so that the saw can be used for circle cutting by rotating the blade assembly 90 DEG from the straight ahead position. This circle cutting can also be at a bevelled angle if desired. A further center pivot bearing assembly is provided at one end of the guide assembly and can be used for cutting larger diametered circles in the work-piece.
