Abstract: The specification discloses a saw having a circular saw blade wherein a motor for driving the saw blade and a bearing for the saw blade spindle are mounted on a mounting frame which is positioned below a work table and can be raised and lowered in a pivoting movement about a horizontal pivoting axis parallel to the spindle axis. The mounting frame is suspended in a tiltable cradle suspended in a circular work support which is flush with the top of the work table and is rotatably mounted in a circular opening therein. When the mounting frame is raised the saw blade will project through a slot in the support. The mounting frame is operated by a thin bar projecting through the slot in the support and carrying a handle above the work table. The bar is integral with a riving knife. It is rotatably mounted about the saw blade axis, and it is connected to the cradle by a linkage formed by an articulated rod and the mounting frame.
