PROBLEM TO BE SOLVED: To provide a power tool enabled to detect a rotational fluctuation state of the power tool with higher accuracy.SOLUTION: A power tool is a hand-held power tool and includes a first sensor 114 that detects first driving information corresponding to a movement state of a tool body 101 when a tool body 101 is rotated around the longitudinal axis of a tool bit 119 during the working operation, a second sensor 115 that detects second driving information corresponding to output torque of the tool bit 119 driven by a motor 110, and a controller 113 connected to the first sensor 114 and the second sensor 115 for controlling the power tool. The controller 113 is configured to calculate holding information corresponding to a holding force of a worker to hold the tool body 101 based on both of the first driving information and the second driving information, and control the drive of the power tool based on the holding information. |
