ABSTRACT:
An elongated portable frame is provided including front and rear ends and a mid-length laterally outwardly projecting tubular handle for containing a battery pack. The front end of the frame journals a saw blade therefrom and the saw blade is driven by an electric motor supported from the frame. A pair of rearwardly retractable jaws are disposed on opposite sides of the forward periphery of the saw blade and are opposed by a rearwardly retractable jaw structure disposed forwardly of the forward limit positions of movement of the jaw members and an actuator for the jaw structure is disposed immediately forward of the handle for engagement and rearward displacement by the forefinger of a hand encircling the handle, whereby the jaw structure may be shifted rearwardly to initially clamp a work piece to be cut between the jaws and the jaw structure and thereafter utilized to rearwardly advance the work piece to be cut relative to the saw blade. The rear of the frame journals rearwardly facing inner and outer conical grinding stones for outwardly and inwardly beveling, respectively, cut ends of tubular work pieces severed by the saw blade.
