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).

IPC: B25D16/00
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).

Abstract: A power tool efficiently cools a motor and a brush, with a distance for insulation left between an inlet and an urging member. A power tool includes a motor, an output unit, a fan, a housing accommodating the motor and the output unit, having an inlet to suck in air from outside in response to rotation of the fan and an outlet to discharge the air sucked in, and accommodating the motor along a flow of the air between the inlet and the outlet, a brush retainer downstream from the inlet and including a brush and a conductive urging member urging the brush against a commutator, and a nonconductive cover located between the urging member and the inlet and covering the urging member.
