Abstract: An attachment for a sabre saw which enables the sabre saw to be utilized as a motorized hack saw. The attachment includes an attachment guide adapted to be secured to the guide plate of the sabre saw, a hack saw positioned in the attachment guide for reciprocation with respect thereto and a coupling for securing the hack saw to a reciprocal member of the sabre saw. A handle is secured to the attachment guide to facilitate handling of the hack saw attachment in assembly with a sabre saw. In addition, heat insulating material is place on portions of the attachment guide to reduce friction created external temperatures of the portions of the attachment guide.
