A portable grinding machine (10) includes an elongated housing (12, 14) and an output shaft (16) projecting at a right angle to the housing axis for receiving a disk-shaped rotary clamping tool. The output shaft is encompassed by a substantially cylindrical clamping collar (30), on which a shell-like protective cover (20) is secured in a tensile manner against rotation and axial displacement and which serves for encompassing the clamping tool (18) and which can be attached on the clamping collar (30) by means of a ring-shaped tensioning belt (28). The tensioning belt (28) has sharp-edged projections (32) projecting to the clamping collar, which upon clamping, bore into the clamping collar and are held there in a form-locking manner (a shell-like tensioning band).
