A b s t r a c t The invention relates to a manually operated shearing machine, driven by an ordinary drill, intended for shearing sheet-metal thicknesses up to about 5 mm. The machine comprises a body (1) provided with support wheels (24, 25), two cutting wheels (5, 6) cooperating with each other on the body (1), the sheet-material being sheared between the cutting edges (18, 19) thereof. The cutting wheels (5, 6) are arranged obliquely at an angle .alpha. to the normal plane of the sheet-material to be sheared. Furthermore, the free side faces (12, 13) of the shearing wheels (5, 6) are bevelled close to the shearing edges (18, 19) at the same angle .alpha. , forming peripheral surfaces (16, 17). The shearing wheels (5, 6) are also arranged in such a way in relation to each other that said peripheral surfaces (16, 17) lie in the same plane and form a nip (20). Thus, after sharpening of the cutting edges (18, 19), for example, the position of the shearing wheels (5, 6) in relation to each other can easily be adjusted by vertical displacement of one of the shearing wheels.
