    Abstract: A rechargeable electric power tool includes a battery pack that is detachably provided on a housing accommodating a motor and that supplies electric power to the motor, and a tool that is driven by the motor. A standby switch and a lock-on switch are arranged at the housing. The standby switch is able to set the rechargeable electric power tool to a standby state where the rechargeable electric power tool waits for the motor to be driven. The lock-on switch is able to shift the rechargeable electric power tool from the standby state to a state where the motor is driven so as to keep the state where the motor is driven.

    Abstract: An electric power tool may include a three-phase brushless motor configured to drive a tool, a gear reducer provided between the motor and the tool. The gear reducer is configured to selectively change a reduction ratio from the motor to the tool between a first reduction ratio and a second reduction ratio. The electric power tool may further include a motor controller configured to drive the motor with rectangular waves. The motor controller is configured to selectively change a conduction angle of each rectangular wave between at least a first conduction angle and a second conduction angle.
