Abstract: A dust collecting attachment for an electric power tool includes dust collecting fans, a suctioning portion, and a dust collecting portion. The suctioning portion generates a suctioning force by rotation of the dust collecting fans. The dust collecting portion captures dust suctioned from the suctioning portion. When the dust collecting attachment is mounted to an electric power tool including a motor, a fan shaft of the dust collecting fans is connected to a rotation shaft that is disposed in the electric power tool and rotates in accordance with driving of the motor to allow the dust collecting fans to rotate integrally with the rotation shaft. The dust collecting fans are disposed in a plurality of stages in an axial direction of the fan shaft.

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.

Abstract: A rotary hammer includes a tool body, a tool holder, a cylinder, and a coupling member. The tool holder has a tubular shape and a longitudinal axis. The tool holder is configured to hold a tool accessory to be movable along the longitudinal axis and is supported by the tool body to be rotatable around the longitudinal axis. The cylinder extends coaxially with the tool holder and is supported by the tool body to be rotatable around the longitudinal axis. The coupling member is between the tool holder and the cylinder in a radial direction of the tool holder and is engaged with the tool holder and the cylinder to couple the tool holder and the cylinder together such that the tool holder and the cylinder integrally rotate.

Abstract: A rotary hammer includes a motor, a manipulation member, a main switch, a mode-switching member, a first locking member and a second locking member. The first locking member is configured to selectively lock the manipulation member in an OFF position according to a switching position of the mode-switching member. The second locking member is configured to selectively lock the manipulation member in an ON position according to the switching position of the mode-switching member. The first locking member is allowed to lock the manipulation member in the OFF position both when a hammer mode has been selected and when a drill mode has been selected. The motor is allowed to be driven in a state in which the manipulation member is locked in the ON position by the second locking member only when the hammer mode has been selected.
