Abstract: An impact rotary tool includes a motor, a hammer, an anvil, a sensor, a circuit board, and an isolator. The hammer is configured to receive rotational force around an axis from the motor and output striking rotational force which is obtained by converting part of the rotational force into striking force around the axis. The anvil to which a tip tool is to be attached is configured to rotate, together with the tip tool, around the axis in response to the striking rotational force received from the hammer. The sensor is disposed in a vicinity of the anvil and is configured to sense a change in a state of the anvil, the change being according to the striking rotational force. The circuit board is configured to receive a sensing result by the sensor. The isolator isolates contact portions of the hammer and the anvil from at least the circuit board.

Abstract: An electric tool includes a fastening unit, a control unit, a sensor unit, a communications unit, a storage unit, and a portable tool body. The sensor unit measures at least fastening torque applied by the fastening unit. The communications unit transmits operations data about a result of measurement made by the sensor unit. The communications unit includes a wireless communications unit and a wired communications unit. In a wireless communication mode, the wireless communications unit transmits, by a wireless communication method, at least a part of the operations data, when a fastening operation has been done for either one round or multiple rounds. In a wired communication mode, while the communications unit is operating in the wired communication mode, the wired communications unit transmits, by a wired communication method, the operations data stored in the storage unit.

Abstract: An impact tool includes a motor, an output block, a hammer, and a magnetostrictive sensor. The magnetostrictive sensor includes a magnetostrictive member and a coil portion covering the magnetostrictive member. The output block includes a claw block and a body block. The claw block includes an anvil claw, against which a hammer claw collides. The claw block has been subjected to quenching treatment. The body block includes a thermally sprayed portion and is coupled to the claw block. The thermally sprayed portion includes, on a surface thereof, the magnetostrictive member made of a magnetostrictive material.
