The invention relates to a portable circular saw (10) comprising a sawblade holder (33) which is designed to secure a sawblade (30) and which can be rotated about a drive axis (34) by means of a drive assembly (20). A protective cover (24) is provided which surrounds a chip-guiding area (24.11), within which a sawblade receiving region (24.12) is formed which is arranged and designed to receive the sawblade (30) in a working position, wherein the protective cover (24) has a lateral outer wall (24.6) which delimits the chip-guiding area (24.11) on the face facing away from the drive assembly (20), and a lighting assembly (70) with at least one lighting element (71) is provided in order to illuminate the cutting region of the portable circular saw (10) at least in some regions. The lighting element (71) is arranged behind the sawblade receiving region (24.12) in the advancing direction (V) of the portable circular saw (10). In order to improve the operating comfort, the invention proposes that the lighting assembly (70) is arranged and designed such that light emitted by the lighting element (71) is emitted largely in the advancing direction (V) of the portable circular saw (10), in particular without producing glare for a user of the portable circular saw (10), and light emitted by the lighting element (71) runs in a light-guiding region (24.13) at least in some regions, preferably completely in the light-guiding region, said light-guiding region being separated from the dust-guiding region of the chip-guiding area (24.11).
The invention relates to a light module (70) for a circular hand saw (10), the light module comprising a lamp housing (75) within which a voltage supply is accommodated, a lighting element (71) being electrically connected to the voltage supply. The lighting element (71) is arranged so as to emit light in an emission region on one side of the lamp housing (75) toward a working region of the circular hand saw (10), and the lamp housing (75) comprises a fastening portion (76) which forms a fastening side with a contact surface (72) which is arranged and oriented so as to be removably fastened to a fastening surface of the circular hand saw (10). By means of such an arrangement, a user is provided with the opportunity to suitably illuminate the working region next to the circular hand saw depending on their individual requirements.
A hand-held power tool includes a guide plate including a bearing surface and a top face. A drive assembly includes a drive motor supported above the top face and configured to drive a cutting tool. An illumination arrangement is configured to emit a light cone onto the cutting tool in a direction of travel of the power tool. When the cutting tool is in a locked cutting position in which the drive assembly is locked in position with respect to the guide plate and the cutting tool projects beyond the bearing surface, the cutting tool is disposed in a light path of the light cone to generate a cast shadow of the cutting tool on an end face of the workpiece to be cut, which end face faces the cutting tool and is oriented transversely to the bearing surface of the guide plate.
