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.
