Abstract
The invention provides a new and improved diamond saw blade for use in cleaning the joints commonly found between concrete sections or slabs. The diamond cutting blade designed in accordance with the present invention provides a thin metal disk with a plurality of abrasive segments secured to the circumferential edge, the blade being adapted for rotation about an axis of rotation. The segments are symmetrically spaced about portions of the periphery of the disk in close end-to-end alignment with one another. A plurality of large elongated openings or gullets are formed in the disk symmetrically spaced in an annular zone located along the periphery of the blade. The gullets occupy at least 30%, and preferably at lest 40% of the outer periphery or circumference of the blade. With this arrangement, the gullets allow the blade to efficiently remove sealant from the joints of concrete.
