The motor includes a motor shaft rotatable around a first axis. The tool holder is configured to be rotationally driven around a second axis extending parallel to the first axis and defining a front-rear direction. The grip part is behind the main housing and extends in a direction crossing the second axis. The grip part includes a first end portion located on the second axis and a second end portion spaced apart from the second axis. The connection part connects the second end portion and the main housing. The connection part and the grip part together form an annular part. The detection device is disposed in the connection part and configured to detect a rotation state of the main housing around the second axis.

Abstract: A power tool (100) comprises a motor (110) operably driving a tool bit (119), a tool body (101) housing the motor (110), a handle (109) coupled to the tool body (101), and at least two battery mount parts (160A, 160B) defined on the handle (109) and/or the tool body (101). Each of the battery mount parts (160A, 160B) comprises a battery engaging part (161) configured to detachably engage with battery packs (170A, 170B) by sliding the battery packs (170A, 170B) relative to the battery engaging part (161) in a direction perpendicular to the longitudinal direction of the tool bit (119). In a state in which at least one of the battery packs (170A, 170B) is mounted on at least one of the battery mount parts (160A, 160B), a length of the mounted battery in a driving axis extending direction is shorter than a length of the mounted battery in a cross direction.
