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.

Abstract: An impact tool includes a motor, a driving mechanism, and a vibration sensor. The driving mechanism is configured to perform a hammering operation of linearly driving a tool accessory along an impact-axis by power of the motor. The impact-axis extends in a front-rear direction of the impact tool. The vibration sensor is configured to detect vibrations. The vibration sensor is disposed such that the vibration sensor is capable of detecting vibrations of a first frequency among vibrations caused in the impact tool, and such that transmission of vibrations of a second frequency to the vibration sensor is suppressed. The vibrations of the first frequency result from the hammering operation. The second frequency is different from the first frequency.

Abstract: A power tool, such as a hammer drill (100), has first and second battery mount parts (160A, 160B) that are aligned in a longitudinal direction of the power tool. First and second batteries (170A, 170B) are mountable thereon in series along a straight line that extends in the longitudinal direction. The first battery (170A) is mounted on the first battery mount part (160A) by sliding along the straight line towards the second battery mount part (160B). The second battery (170B) is mounted on the second battery mount part (170B) by sliding along the straight line towards the first battery mount part (170A).

Abstract: A power tool having a rotary hammer mechanism has a first motor; a driving mechanism configured to operate by power of the first motor in an action mode selected from a plurality of action modes including a first mode of at least rotationally driving a tool accessory and a second mode of only linearly driving the accessory; a tool holder configured to be rotationally driven by torque transmitted from the first motor; a second motor; a clutch member configured to transmit torque to the holder in a transmitting position and to interrupt the transmission in an interrupting position; and a transmitting mechanism configured to convert rotation of the second motor into linear motion and transmit the linear motion to the clutch member. When the tool body excessively rotates around the driving axis, the second motor moves the clutch member from the transmitting position via transmitting mechanism to interrupt the transmission.

Abstract: In a dust collector for electric power tool, while a casing includes a tubular suction opening portion disposed to protrude forward, a dust collecting route is formed in the casing to ensure capturing a dust suctioned with an air by a filter disposed in a dust box. The suction opening portion is abutted on a surface to be processed and a tool bit of a hammer drill is passable through the suction opening portion. The dust collecting route suctions the air from the suction opening portion and guides the air into the dust box disposed to the casing. The dust box includes a dust removal device (rubber) configured to directly act to the filter from outside to remove the dust accumulated on the filter.
