Abstract: A dust collecting attachment includes a dust suction portion and a main body. The dust suction portion has a suction opening through which a tip tool is allowed to pass. The main body has a dust collection passage communicated with the dust suction portion and connectable to an external hose. The main body includes a suction space, an air vent hole, and an air vent operation portion. The suction space is communicated with the dust collection passage and has a suction port opening to a workpiece. The air vent hole opens the suction space to outside. The air vent operation portion normally closes the air vent hole and opens the air vent hole by a predetermined operation. The air vent operation portion is operated together with an operation of removing the main body from the workpiece to open the air vent hole.

Abstract: A dust collecting attachment includes a dust suction portion and a main body. The main body has a dust collection passage communicated with the dust suction portion. The dust suction portion has a negative pressure by exerting a suction force to the dust collection passage from a hose. The dust suction portion includes an inner pipe through which a tip tool passes, a first dust suction flow passage, and a second dust suction flow passage. The first dust suction flow passage opens a first suction opening to a side of a workpiece in an outside in a radial direction of the inner pipe and is communicated with the dust collection passage. The second dust suction flow passage opens a second suction opening to an opposite side of the workpiece in the outside in the radial direction of the inner pipe and is communicated with the dust collection passage.
