ABSTRACT:
A cutting tool comprising a cutter body member having a generally circular shape, a front surface, a back surface and an axis of rotation, the cutter body member includes an outer portion comprising a plurality of individual projections arranged spaced from one another about the cutter body with the space between successive projections defining receiving slots for cutting blades. The individual projections each further comprise an outer surface with at least one of the outer surfaces including a protrusion. Each of the blade receiving slots comprises opposing first and second side surfaces and an inner end portion with the inner end portion having a pair of angled mounting surfaces, one of the mounting surfaces extends from the first side surface and the other mounting surface extends from the second side surface with the angled mounting surfaces extending toward one another. Each of the angled mounting surfaces is oriented at an angle of less than 90 degrees with respect to its respective side surface. Preferably, one of the mounting surfaces is oriented at an angle of about 60 degrees while the other mounting surface is oriented at an angle of about 30 degrees.
