ABSTRACT:
The invention relates to a power tool such as a router which is provided to perform an operation on a work piece. The tool includes dust extraction apparatus to allow dust and debris to be removed from the location at which the work is performed and part of the extraction apparatus is movable between storage and in-use positions. When said part is moved to a storage position, an alternative dust extraction passage may be fitted in to the port or aperture. Typically, the part which is movable can be telescopically movable or alternatively, can be provided of a flexible member so as to be moved between extended and retracted positions.
