ABSTRACT:
A two-tier groove cutting circular saw blade includes a circular middle core having sectors defined about the periphery, a pair of side cores disposed adjacent opposite surfaces of the middle core and having lands defined about their outer peripheries, and pluralities of outer and inner cutting segments are secured to the respective middle core sectors and side core lands. Each side core is smaller in diameter than the middle core such that the side core lands and inner cutting segments secured thereon are displaced radially inwardly from the middle core sectors and outer cutting segments secured thereon, thereby adapting the blade for cutting a narrow lower tier and a wider upper tier of the two-tier groove. The blade also includes core anti-undercut features provided on the middle and side cores at predetermined locations thereon for defining exit paths for flow of material particles generated from the cutting of the groove and flushing of the groove by fluid coolant. The side cores of the blade can be interlocked with the middle core by flanges on their peripheries extending through windows or recesses in the middle core adjacent to the peripheries of the side cores. The blade can also employ spacers between adjacent facing surfaces of the side cores and middle core for positioning the side cores at predetermined spacings from the middle core for presetting the width of the upper tier of the groove.
