Abstract
A device for the temporary fixation of a portable cutting machine to a template for making holes and/or recesses in a workpiece including a guide sleeve and a tensioning unit. The guide sleeve includes a tubular hub with an outer diameter corresponding to an inner diameter of an aperture in the template, a forward end of the hub having radially extending lugs configured and located so as to match corresponding recesses in the aperture during the insertion of the guide sleeve therein and to obtain a locking engagement with an inner surface of the template after a partial rotation of the guide sleeve relative to the template. A rearward end of the hub has a tubular adapter socket that is mounted to a nose portion of the cutting machine. The tensioning unit is mounted to the adapter socket for axial displacement relative thereto and having a forward end surface for engagement with an outer surface of the template.
