Title: Manual sanding machine tool

Abstract: A manual grinding tool, in particular an oscillating sander (10), with a housing (12) and an abrasive sheet carrier (14), against the working surface (15) of which an installable abrasive sheet (16; 150) rests, whereby said abrasive sheet is installed using clamping means (20, 23; 360, 500) which clamp opposite abrasive sheet ends (17, 19; 155) to the abrasive sheet carrier (14), is made easier to operate and handle because it is lighterweight and more effective by the fact that the clamping means (20, 23; 350, 500), together with an abrasive sheet end (17; 155) clamped thereto, are capable of being moved away from the diametrically opposed abrasive sheet end (19; 155) which is also clamped thereto, so that said abrasive sheet is locked under tensile stress, whereby the clamping means are composed of resilient material.
