Abstract: An impact tool includes: a brushless motor; a spindle, which is rotated by the brushless motor; a hammer, which is held on the spindle; an anvil, which is impacted in a rotational direction by the hammer; a polymer housing, which houses the brushless motor; a hammer case, which is connected to the polymer housing and houses the hammer and the spindle; and a light unit, which is held on the hammer case and comprises a plurality of light-emitting devices. The maximum tightening torque of the anvil is 1,000 N·m or more and 2,500 N·m or less.

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.

Abstract: An angle impact tool includes: a brushless motor having a stator and a rotor, which rotates around a first rotational axis relative to the stator; an impact mechanism, which is rotated by the rotor; an output shaft, which is impacted by the impact mechanism and rotates around a second rotational axis; a motor housing, which houses the brushless motor; and one or more battery-mounting parts, on which one or more battery packs is (are respectively) mounted. In a front-rear direction, which is orthogonal to the second rotational axis, the impact mechanism and the output shaft are disposed more forward than the brushless motor. The front-rear direction and the output shaft are orthogonal to each other. The maximum fastening torque of the output shaft is 500 N·m or more and less than 1,000 N·m.

Abstract: A power tool includes a motor, an output shaft that is rotated by a rotational force of the motor, a chip-on-board light emitting diode disposed around the output shaft, and a white translucent optical member including a light refraction portion that refracts light emitted from the chip-on-board light emitting diode. In at least one cross section parallel to and passing through a rotation axis of the output shaft, a shape of the light refraction portion is line-symmetric with respect to the rotation axis.
