  • Chip deflector for a circular saw
    Patent number: 6543142
    Abstract: A kerf deflector for a circular saw is mounted by wedging the deflector between a mounting bolt on the saw and a lip on the table of the saw. The deflector is constructed of clear plastic sections enabling the user to align the advancing blade with the cut line on the board. One section scoops up air from the rotating blade and directs the air between another section and the board surface being cut. The narrowing construction of the air passage strengthens the stream of air on the basis of the venturi principle.
