A duct mechanism for directing a flow of air onto a working member of a power cutting tool generally includes a housing, a motor in the housing, a working member actuated by means of the motor and a shoe pivotally mounted relative to the working member and adapted to engage a workpiece. The duct mechanism includes an inlet portion mounted to the housing. The inlet portion receives a stream of air from the housing. An outlet portion is connected to the shoe for directing the stream of air onto the working member in a direction transverse to a line of action of the tool. At least one connecting portion connects the inlet portion and the outlet portion. The at least one connecting portion allows the outlet portion to pivot with the shoe relative to the inlet portion.
