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.
A method of removing dust from a workpiece during operation thereon by a power tool having a housing, a motor in the housing, and a working member adapted to be actuated by means of said motor, the method comprising directing a stream of pressurised gas onto said working member from a first side thereof and in a direction transverse to a line of action of the tool, and providing, on a second side of the working member opposite to said first side, an inlet to a suction tube connected to a suction source.
A method of removing dust from a workpiece during operation thereon by a power tool having a housing, a motor in the housing, and a working member adapted to be actuated by means of said motor, the method substantially as hereinbefore described with reference to the accompanying drawings.
A dust extraction apparatus for use in removing dust from a workpiece during operation thereon by a power tool having a housing, a motor in the housing, a working member adapted to be actuated by means of said motor, and a support shoe adapted to engage the workpiece, the apparatus comprising:
