Abstract: A power tool includes an anvil (14) operably driven by a motor (10); an insertion hole (91) defined the anvil, into which a bit is insertable; a through hole (92) extending radially from the insertion hole; a ball (93) disposed in the through hole; and a manually-movable sleeve (99) mounted around on the anvil and being axially slidable relative to the anvil. At a retracted position, the manually-movable sleeve presses the ball radially inwardly. At an advanced position, the manually-movable sleeve releases the pressing of the ball. A flat spring (97) is configured to bias the ball radially inwardly. The manually-movable sleeve has a length such that the flat spring is exposed at the advanced position.

Abstract: A power tool including a motor and an impact mechanism. The impact mechanism is coupled to the motor and includes a hammer driven by the motor, and an anvil positioned at a nose of the power tool, and configured to receive an impact from the hammer. The power tool also includes a sensor assembly positioned at the nose of the power tool, and an electronic processor. The sensor assembly includes an output position sensor configured to generate an output signal indicative of a position of the hammer or the anvil. The electronic processor is coupled to the output position sensor and to the motor, and is configured to operate the motor based on the output signal from the output position sensor.

Abstract: A rotary impact tool including a housing, a motor, a gear assembly, and a drive assembly. The motor includes a shaft configured to rotate about an axis. The gear assembly is operably coupled to the motor. The drive assembly is configured to convert continuous torque received from the shaft through the gear assembly into periodic rotational impacts upon a workpiece. The drive assembly includes a camshaft, an anvil, a hammer, and a thrust bearing. The camshaft is operably coupled to the gear assembly. The anvil is positioned adjacent to a forward end of the camshaft. The hammer is configured to reciprocate along the camshaft to impart rotational impacts to the anvil in response to rotation of the camshaft. The thrust bearing is engaged with the camshaft such that the thrust bearing is configured to at least partially support the camshaft in an axial direction.

Abstract: An impact tool includes an electric motor, an output shaft, a grip, and an impact assembly. The impact assembly is used for providing an impact force for the output shaft and includes an impact block driven by the electric motor and a hammer anvil mating with the impact block and impacted by the impact block. The maximum radial dimension of the impact block is greater than or equal to 44 mm and less than or equal to 50 mm, and tightening torque outputted from the impact tool to a workpiece is greater than or equal to 250 N·m. The impact tool ensures good impact performance and is compact and light.

Abstract: An electric tool includes an output shaft and a controller. The output shaft is configured to hold a tip tool and be rotated by motive power provided from an electric motor with the output shaft holding the tip tool. The controller is configured to control rotation of the output shaft in accordance with pressing force in a direction from a tip end of the tip tool toward the output shaft. The electric tool has, as an operation range, a restriction range in which rotation of the output shaft is restricted in a state where the pressing force is less than or equal to a prescribed value.
