Abstract
Disclosed is a feature that collects dust particles that arise from a processing operation of an impact tool. The dust collection device collects dust that arises from of a processing operation and is attached to the impact tool that performs a pre-determined processing operation on a processed member by way of a tool bit mounted to the tip region of the tool body being linearly operated at least in the lengthwise direction. The dust collection device has a dust collection unit of which the tip opens as a dust intake port and the contour shape is formed unevenly around the long axis of the tool bit. The position of the dust collection unit is freely selected around the long axis of the tool bit, and it is possible to cause the position to change around the long axis of the bit.
