<p>Various grinding tools, such as a disk-shaped grinding stone for grinding a steel material and a cup-shaped diamond wheel for grinding concrete, can be attached to a disk grinder depending on the substance of a work. In order to secure heat resistance to heated iron powder or the like generated during the work, typically, a dust collection cover is made from a steel material. Therefore, conventionally, it has been difficult to achieve reduction in weight of a dust collection cover, hence, it is an object of the present invention to achieve reduction in weight of the dust collection cover. The dust collection cover (10) is made from resin for achieving reduction in weight. In this connection, it is configured such that a disk-shaped grinding stone for grinding a steel material is not attachable because of interference with an attachment restricting portion (20) and that only a cup-shaped diamond wheel (T1) for a work that does not produce heated iron powder or the like is attachable.</p> |
