In gas-spring-type knock-in tools in which an impact piston is returned to top dead center by using an electric motor as a drive source, thereby raising the gas pressure in a pressure accumulation chamber, causing the impact piston to move downward, and knocking in a knock-in implement, filling the prior-art pressure accumulation chamber with compressed gas and opening said chamber to the atmosphere takes time, and operations for resolving nail jamming have been troublesome. It is necessary to implement a more operable measure against jamming. A pressure accumulation chamber (20) is provided with a filling valve (22), a relief valve (23), and an opening valve (24). Connecting an external device (2) to the filing valve (22) makes it possible to quickly fill the pressure accumulation chamber (20) with compressed gas. The pressure accumulation chamber (20) is held at a set pressure by the relief valve (23). The pressure accumulation chamber (20) can be quickly opened to the atmosphere using the opening valve (24). This makes it possible to quickly perform an operation for resolving nail jamming in a knock-in nose part (18).

Provided is a rotary tool capable of more flexibly determining the possibility of excessive rotation of a tool body caused by locking of a tip tool. A driver drill (1) is provided with a tool body (10), a motor (2), and a controller (5). The motor (2) is housed in the tool body (10) and configured to drive a tip tool. The controller (5) is configured to determine whether excessive rotation of the tool body (10) about the drive axis (A1) caused by locking of the tip tool occurs in accordance with specific determination criteria. Further, the controller (5) is configured to monitor information relating to the use state of the driver drill (1). Still further, the controller (5) is configured to change the determination criteria for determining whether the excessive rotation occurs in accordance with the use state of the driver drill (1).

Provided is a rational configuration for suitably determining the likelihood of excessive rotation of a tool body of a drilling tool due to locking of a tip tool. A driver drill (1) comprises: a tool body (10); a brushless motor (2); a current sense amplifier; an acceleration sensor (71); and a controller (5). The current sense amplifier detects a current value of the motor (2) which corresponds to a load acting on a tip tool. The acceleration sensor (71) detects the acceleration which corresponds to the state of rotation of the tool body (10) about a drive shaft. The controller (5), which is configured to control the operation of the driver drill (1), is configured to set a conduction angle for the motor (2) on the basis of the current value of the motor (2) and is configured to determine, on the basis of the current value and the acceleration of the motor (2), whether excessive rotation of the tool body (10) due to locking of a tip tool occurs.

The present invention ensures the operability of a switch that is suitable for an electric tool with a brushless motor, while achieving a cost reduction for said switch. An electric tool 1 has: a brushless motor 10; a switch body 31 that enters an ON state due to an ON operation and enters an OFF state due to the ON operation being released; an ON operation part 33 that is for performing the ON operation on the switch body 31; and an ON retaining member 35 that automatically engages with the ON operation part 33 when the ON operation part 33 has been operated, and retains the ON operation part 33 in an operated position.
