Abstract:
A handheld circular saw which comprises:a housing and foot assembly for positioning the saw on a workpiece to be cut, an electric motor disposed in said housing which includes a rotatable shalt, a circular saw blade attached to said shaft for cutting the workpiece, an adjustable guide removably attached to said foot assembly for precisely guiding cutting movement of said circular saw blade relative to an edge of the workpiece, said guide including a bar which is mounted parallel to the axis of said shalt, which bar is stepped at a location intermediate of its length to provide a flat upper section and a flat lower section which are aligned in a straight line, said flat lower section having a rectangular cross-section with upper and lower flat surfaces and flat side edge surfaces, and having a longitudinally extending groove formed therein which groove has a bottom surface, a holder which is slidably movable along said lower bar section, said holder including three interior surfaces that lie in close juxtanosition with said upper surface and both said side edge surfaces of said flat lower section, a guide member carried by said holder which includes means defining a straight line which can be slid along the workpiece edge, said holder and said flat lower section interengaging in a manner so that said means defining a straight line is maintained precisely perpendicular to said shaft axis; and said holder having a threaded hole extending therethrough and a clamping screw being threadably received in said hole so that a free end of said screw can be caused to tightly engage said bottom surface of said groove to precisely position said holder and its guide member at a desired longitudinal location along said bar; and means for removably mounting said flat upper bar section upon an upper surface of said foot assembly in a manner so that said bar is precisely parallel to said shaft axis.
