  • Publication number: 20030209107
    Abstract: An improved chop saw may include a base assembly, a blade assembly including a blade having a center and a motor for driving the blade, an arm pivotally attached to the base assembly and carrying the blade assembly, the blade assembly being movable between a lower position for engaging and cutting a workpiece disposed on the base, and an upper position not engaging the workpiece. The chop saw further includes a vise for holding the workpiece in place, the vise including a vise screw, a latch support supporting the vise screw, and a vise jaw disposed at the end of the vise screw. Preferably, the maximum distance between the vise jaw and the latch support is about equal or shorter than the distance between the blade center and the latch support, when the blade assembly is at the lower position. Further the chop saw includes a substantially horizontal handle connected to the blade assembly.
