Abstract: A screw driving includes a housing, a motor, a spindle, a locator, a first detecting mechanism and a controller. The locator is mounted on a front end portion of the housing so as to be movable in a front-rear direction relative to the housing and configured to define a depth to which a screw is driven into a workpiece. The first detecting mechanism is configured to detect a position of the locator in the front-rear direction. The controller is configured to control driving of the motor. Rotational driving of the spindle in a forward direction is started in response to the spindle being pressed rearward, and the rotational driving of the spindle in the forward direction is stopped when the first detecting mechanism detects that the locator is disposed in a specified position rearward of a most forward position within a moving range of the locator.

Abstract: A fastening tool includes a bolt-gripping part, an anvil, a bolt-gripping-part driving mechanism, a motor, a housing, and thrust rolling bearings. The bolt-gripping-part driving mechanism includes a first mechanism part supported by the housing and a second mechanism part connected to the bolt-gripping part. The second mechanism part is configured to be driven in a longitudinal-axis direction by the first mechanism part being rotationally driven, so that the bolt-gripping part is moved in the longitudinal-axis direction relative to the anvil. The thrust rolling bearings are disposed on a first direction side and a second direction side of the first mechanism part, respectively.

Abstract: A cover may be used in a tool with a tip tool. The cover may include an inner cover covering at least a part of the tip tool and an outer cover covering at least a part of the inner cover. In the cover, a space between the inner cover and the outer cover may constitute a suction path through which suctioned air flows. In the cover, a shape of the suction path may be changeable by a change in a relative positional relationship between the inner cover and the outer cover.

Abstract: A box-type dust collector includes a suction unit that includes a brushless motor and an air blowing fan, a battery mount portion, to which a battery pack that serves as a power source is mountable, a suction port that suctions outside air through rotation of the air blowing fan, and a filter that separates dust from the outside air which is suctioned from the suction port. The bottom surface of a tank serves as a surface for stationary placement. A handle for carriage is provided at a position directly over the center of gravity of the entire box-type dust collector with the battery pack mounted to the battery mount portion. Coupling portions to be coupled to both ends of a shoulder belt are provided at front and rear positions that are point-symmetric about the center of gravity as viewed in plan.
