Abstract

A portable handheld edge cutter (1) has a cutterhead (2) fixed to a guide tube (4). Two wheels (6, 7) are attached to the cutterhead (2). The cutterhead (2) includes a gear unit mounted in a gear housing (8). A first wheel (7) is rotatably journalled on a first end (27) of the gear housing (8). On the opposite-lying end (28) of the gear housing (8), a cutting knife (9) is mounted and is rotatably driven by the output shaft (18) of the gear unit. In order to achieve a simple assembly of the edge cutter (1) and to protect the gear housing (8) against wear, the second wheel (6) is mounted between the gear housing (8) and the cutting knife (9) and that the two wheels (6, 7) are journalled coaxially to the output shaft (18).
