A CIRCULAR SAW

摘要

A circular saw (10) is provided which can operate in two modes. In a first mode, the circular saw (10) operates in a conventional manner; in a second mode the circular saw (10) can be turned through 90° to operate in an undercutting mode, for undercutting a wall mounted door (D), for instance. To achieve this, the blade shroud (22) comprises an outer surface (36) facing away from the saw's motor housing (12) which is flat for engagement with a floor surface (FS) or a guide rail (30). Advantageously, the outer surface (36) might comprise a groove or channel (38) arranged to cooperate with a guide rail rib (32).
