<p>A jigsaw ( 2 ) having a housing ( 4 ) and a jigsaw support shoe ( 16 ) is disclosed. A motor in the housing ( 4 ) causes reciprocating motion of a jigsaw blade, and causes a fan in the housing to emit air from the housing. Air is driven by the fan via a connector piece ( 22 ) and a bridge member ( 20 ) towards the jigsaw blade in a direction transverse to a line of cutting action of the jigsaw ( 2 ). An inlet of a suction tube, connected to a source of suction such as a vacuum cleaner, is provided on the opposite side of the jigsaw blade to the bridge member ( 20 ). Provision of a stream of air in a direction transverse to the line of cutting action of the jigsaw ( 2 ) allows the outlet of the bridge member ( 20 ) to be located close to the jigsaw blade without obscuring the user's view of the location at which the blade cuts the workpiece, while the provision of an inlet to a suction tube on the opposite side of the jigsaw blade further constrains the stream of air to improve dust extraction.</p> |
