ABSTRACT:
A circular saw (14) has blower attachments (10) and (12) for producing a sufficiently strong air current directly in front of the circular saw blade (18) to blow away saw dust from about the lead guide (34) that is aligned directly in front of the saw blade. The lead guide is mounted at the front edge of the foot (30). The attachment (10) is a fan mounted about the arbor of the circular saw and abuts the saw blade to also provide damping effect that reduces noise vibration. The attachment (12) has a funnel inlet section (60) mounted against the exhaust vent section (38). A self supporting flexible pipe (66) extends from the funnel inlet section and has a free standing distal end (67) that can be adjustably pointed to the lead guide (34) to allow passage of air flow from the exhaust vents to the lead guide.
