An electric power tool (1) includes a motor (30) having a drive shaft (32), a tool output shaft (60) rotated by rotational force of the drive shaft (32), a clutch unit (50) that connects or disconnects a torque transmission line between the drive shaft (32) and the tool output shaft (60) according to load torque of the tool output shaft (60), a load detector (81) that outputs a load torque signal (SL) in accordance with the load torque (TL) of the tool output shaft (60), and a control unit (100) capable of performing a rising detection mode, which detects rising of the load torque signal (SL) to stop rotation of the motor (30), and a falling detection mode, which detects falling of the load torque signal (SL) to stop rotation of the motor (30). The control unit (100) selects the rising detection mode or the falling detection mode according to a usage condition signal (SL/SN/SS/SV/ST/SB) indicating a usage condition of the electric power tool. |
