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.
