Abstract: A grinder includes a motor, a housing, a spindle and a cover. The spindle protrudes downward from the housing, is driven by the motor, and thereby rotates. The cover is provided on the spindle in the circumferential direction and at least partially covers a tool accessory, which is mounted on the spindle. The cover is configured such that at least one part deforms and/or is composed of an elastic material.

Abstract: A hand-held power tool includes a motor having a stator and a rotor, the motor being configured to rotate the rotor at a speed of at least 40,000 rpm, an output shaft directly driven by the rotor, a tool accessory shaft configured to support a tool accessory, and a two-stage speed reducing transmission operably connecting the output shaft to the tool accessory shaft. The two-stage speed reducing transmission is configured to drive the tool accessory shaft at a rate less than the rotor speed, for example, at a rate less than or equal to 37.5% of the rotor speed.

Abstract: In a hammer drill, a coil spring that urges a first clutch and a second clutch in directions away from each other is held between a first change plate that engages with the first clutch to be slidable in the axial direction of an intermediate shaft and a second change plate that engages with the second clutch to be slidable in the axial direction of the intermediate shaft. The first change plate is slidably guided by a gear housing.

Abstract: A dust collector includes a main-body housing and a motor assembly disposed in the main-body housing. The motor assembly includes a blower fan, which is disposed in the interior of the main-body housing; and a suction motor, which rotates the blower fan. The motor assembly generates suction force at a suction port, which fluidly communicates with the interior of the main-body housing. At least first and second air-exhaust passageways are respectively in the up-down direction in the interior of the main-body housing and through which air exhausted from the motor assembly flows.

Abstract: A dust collector includes a main-body housing and a motor assembly disposed in the main-body housing. The motor assembly includes a blower fan, which is disposed in the interior of the main-body housing; and a suction motor, which rotates the blower fan. The motor assembly generates suction force at a suction port, which fluidly communicates with the interior of the main-body housing. At least one filter is disposed in a fluid communication path between the suction port and the blower fan. A filter cleaning apparatus is configured to clean the at least one filter. A cleaning-control part is configured to actuate the filter cleaning apparatus after a power tool, which is fluidly connected to the suction port, stops operating.
