摘要： A grinder (1) includes a controller (74) that controls the drive of a brushless motor (6) and both are housed inside a main body housing (2). A battery pack (5) is mounted on the main body housing (2) and serves as the power supply. When a centrifugal fan (30) provided on a rotary shaft (26) of the brushless motor (6) rotates, outside (cooling) air is drawn in through air-suction ports (87) provided in the main body housing (2) and passes through the brushless motor (6). The controller (74) is disposed adjacent to a terminal block (69) that is provided on a battery-mount part (4) of the main body housing (2) and is electrically connected to the battery pack (5). The air-suction ports (87) are disposed between the controller (74) and the terminal block (69) so that the terminal block (69) is also cooled by the incoming outside (cooling) air.
