摘要： 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.

摘要： 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.

摘要： 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.
