Abstract:
Provided is an electric tool with which work efficiency can be improved. A controller of an electric tool can execute: a first control, whereby during a non-operating state after a motor has started up and before a tip tool is set to be in an operating state, the motor is driven at a slow idling rotation speed, and when the tip tool is set to be in the operating state, the motor is driven at a normal rotation speed which is higher than the slow idling rotation speed; and a second control, whereby in a case where a trigger switch has been turned off in a state where the motor is being driven at the normal rotation speed and the trigger switch is thereafter turned on again under a prescribed condition, the motor is driven at the normal rotation speed regardless of the state of the tip tool.
