Abstract: A power tool includes a motor, an output part, a housing, a control circuit board, and a panel. The motor includes a rotor rotatable about a motor rotation axis extending in a front-rear direction. The output part is disposed forward of the motor and is rotated by a rotational force of the rotor. The housing includes: a motor housing part that houses the motor; a grip part that extends downward from the motor housing part; and a battery holding part that is connected to a lower end of the grip part. The control circuit board is housed in the grip part and is configured to control the motor. The panel is disposed at a rear portion of the battery holding part and is manipulated to change a control method of the motor.

Abstract: A power tool includes a tool-main-body part, an electric motor as a drive source, a grip part, which extends downward from the tool-main-body part and is configured to be gripped by a user, and a power-supply unit at a tip of the grip part. The power tool includes a controller configured to control the operation of the electric motor, the controller being located on the power-supply unit, and a display controlled by the controller and configured to indicate an operating state of the electric motor. The controller and the display each have a flat-plate shape and are disposed along a surface direction with respect to one another, and the display includes a first portion that overlies the controller and a second portion that projects beyond an end edge of the controller.

Abstract: An angle tool having an output shaft part the height of which is low is provided. The angle tool includes an output shaft having a chuck part capable of holding a bit, a shaft that is provided so as to intersect the output shaft and that transmits drive force to the output shaft, and a gear housing that accommodates the shaft. The entirety of the chuck part is disposed in the gear housing. The output shaft includes a bevel gear that receives drive force from the shaft, and the chuck part is disposed inside the bevel gear. The chuck part is disposed in front of the shaft so as to intersect an extended line of a center axis of the shaft.
