Abstract: An anvil receives less stress around a rectangular prism and has higher durability. An impact wrench includes a motor, a hammer rotatable by the motor, a body accommodating the motor and the hammer, and an anvil protruding frontward from the body and to be struck in a rotation direction by the hammer. The anvil includes a blade to be in contact with the hammer, a cylinder located frontward from the blade, a rectangular prism located frontward from the cylinder, at least one chamfered surface each at an edge of the rectangular prism, and a concave on a rear end of the at least one chamfered surface.

Abstract: A rotary impact tool according to one aspect of the present invention includes a motor, an impact mechanism, a drive unit, an impact detection unit, and a control unit. The control unit reduces a driving force for the motor caused by the drive unit when a count of impacts detected by the impact detection unit has reached a determination count set in advance, which is a value greater than one.

Abstract: An electric power tool in one aspect of the present disclosure comprises a motor, a hitting mechanism, a hitting detector, and a control unit. The control unit is configured to set a control amount of the motor so that the motor rotates at a lower speed than a speed in the target rotation state during an initial driving period, and switch the control amount to a final control amount corresponding to the target rotation state when the initial driving period elapses. The initial driving period is a period from when generation of a hitting force is detected by the hitting detector until a predetermined first time period elapses, after the motor is started driven.

Abstract: An impact tool includes a motor, a first hammer, an anvil, and a second hammer. The first hammer is configured to be rotated by driving of the motor. The anvil is configured to be hammered in a rotation direction by the first hammer. The second hammer is configured to be switchable between a state being linked and a state not being linked to the first hammer. The impact tool ensures selections of a first hammering mode in which only the first hammer hammers the anvil and a second hammering mode in which the first hammer and the second hammer hammer the anvil.
