To provide a device for temporarily fixing a portable cutting machine to a template (12) for making holes and/or grooves in a workpiece (14).

The device comprise: a guide sleeve (20) having a tubular hub (3) with an outer diameter corresponding to an inner diameter of an aperture (16) in the template (12); a forward end of the hub (30) having radially extending lugs (24) configured and located so as to match corresponding grooves (18) in the aperture (16) during insertion of the guide sleeve (20) therein and to be locked with an inner surface of the template (12) after a partial rotation of the guide sleeve (20) relative to the template (12); a rearward end of the hub (30) coupled to a tubular adapter socket (34) to be fitted to a nose portion (38) of the cutting machine (10); and a tensioning unit (40, 42, 46) mounted to the adapter socket (34) for axial displacement relative thereto and having a forward end surface for engagement with an outer surface of the template (12).
