Abstract: The inclination of a hammer with respect to a spindle is reduced. An impact tool includes a motor, a spindle at least partially located frontward from the motor and rotatable by the motor, a hammer surrounding the spindle, an anvil at least partially located frontward from the spindle and strikable by the hammer in a rotation direction, and three or more balls between the spindle and the hammer.

Abstract: An impact tool (1) includes: a motor (6) having a rotor (27) that is rotatable about a rotational axis (AX); a spindle (8) disposed forward of the stator and rotating when the rotor rotates; an anvil (10) having at least a portion disposed forward of the spindle and mounting a bit (300); a hammer (47), which rotatably impacts the anvil; and a housing (2), which has a motor-housing part (21) that houses the motor. The maximum tightening torque is 140 N·m or more. Overall length (La), which is the distance—in the front-rear direction parallel to the rotational axis—between a rear-end portion of the motor-housing part and a front-end portion of the anvil, is 100 mm or less. Center height Hc, which is the distance in the up-down direction between the rotational axis and an upper-end portion of the motor-housing part, is 29 mm or less.

Abstract: An impact tool has less size increase. An impact tool includes a motor, a spindle, an anvil including an anvil shaft and an anvil projection, a hammer including a hammer projection to strike the anvil projection in a rotation direction, a hammer case accommodating the hammer, an anvil bearing held in the hammer case and surrounding the anvil shaft, and a cup washer facing a front surface of the anvil projection. The cup washer includes an inner ring portion in contact with a rear end face of the anvil bearing, an outer ring portion surrounding the anvil bearing, and a connecting ring portion connecting an outer edge of the inner ring portion and an inner edge of the outer ring portion.

Abstract: An impact tool has less size increase. An impact tool includes a motor, a spindle including a spindle shaft and a flange, an anvil including an anvil shaft and an anvil projection, and a hammer including a base surrounding the spindle shaft, a front ring protruding frontward from an outer circumference of the base, and a hammer projection to strike the anvil projection in a rotation direction. The base has a groove at a boundary with the hammer projection.

Abstract: To reduce size increase, an impact tool includes a motor, a spindle located frontward from the motor, rotatable by the motor, and having a support hole extending rearward from a front end of the spindle, a hammer supported by the spindle, a ball between the spindle and the hammer, and an anvil received in the support hole and strikable by the hammer in a rotation direction. The anvil has a rear end located rearward from the ball.

Abstract: An impact tool (1) includes: a motor (4); a spindle (6), which is disposed forward of the motor and is rotated by the motor; a hammer (33), which is supported by the spindle; an anvil (8), which is impacted in a rotational direction by the hammer; a motor housing (14), which houses the motor; a grip housing (15), which extends downward from the motor housing; and a battery-holding housing (16), which is disposed at a lower-end portion of the grip housing and holds a battery pack (43) having a rated voltage of 18 V. The distance (Da) between a rearward-most edge of the motor housing and a frontward-most edge of the anvil is 97 mm or less.
