ABSTRACT:
A two-tier groove cutting circular saw blade includes a circular core having sectors defined in circumferentially spaced relation to one another along the periphery, and lands defined in circumferentially spaced relation to one another between the periphery and center of the core. Pluralities of outer and inner cutting segments are secured to the respective core sectors and lands. First and second pluralities of anti-undercut elements are defined on the core respectively between the center and periphery thereof and along the periphery thereof between preselected ones of the lands and sectors for defining first and second exit paths away from the inner and outer cutting segments for flow of material particles generated from the cutting of the groove and flushing of the groove by fluid coolant so as to reduce wear and undercutting of the core adjacent to the inner and outer cutting segments. The core has an outer annular portion extending between the lands and sectors of the core and an inner annular portion extending between the lands and the center of the core. The thickness of the inner annular portion of the core is greater than the thickness of the outer annular portion of the core.
