Abstract: A rotary hammer selectively operates in multiple modes including a first mode and a second mode. The rotary hammer includes a switch, a motor, a switch manipulation member, a locking member, and a mode detecting device. The switch manipulation member includes a body, and a protrusion that is movable between a protruding position and a retracted position. The body houses a solenoid configured to operate based on a detection result of the mode detecting device. The locking member is movable between an unlock position and a lock position where the locking member holds the switch manipulation member in an ON position by abutting the protrusion in the protruding position. The protrusion is integrated with a plunger of the solenoid. The protrusion is configured to be in the protruding position when the present mode is the first mode, and in the retracted position when the present mode is the second mode.

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 (160 A, 160B) defined on the handle (109) and/or the tool body (101). Each of the battery mount parts (160 A, 160B) comprises a battery engaging part (161) configured to detachably engage with battery packs (170 A, 170B) by sliding the battery packs (170 A, 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 (170 A, 170B) is mounted on at least one of the battery mount parts (160 A, 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 grinder includes a brake mechanism configured to brake a spindle and an electrical actuator (a solenoid) that actuates the brake mechanism. The solenoid actuates the brake mechanism in conjunction with a turning OFF of a switch from a driving state of a motor, and releases an actuation of the brake mechanism after a lapse of a predetermined period of time from the turning OFF of the switch.

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 power tool includes a hammer mechanism, a brushless motor and a cooling fan. The brushless motor includes a rotary member having a motor shaft operably coupled to the hammer mechanism for linearly driving a tool accessory. The cooling fan has a first blade part and is configured to be rotated by the rotary member. The cooling fan includes a polymer portion, which forms at least a portion of the first blade part, and a metal portion disposed in or on the polymer portion. When viewed in a direction parallel to a rotational axis of the cooling fan, the metal member at least partially overlaps the first blade part in a radial direction of the cooling fan.
