Abstract:
A slotting cutter comprising:a support disc rotatable in a predetermined direction about a central axis, the support disc of a generally cylindrical shape having a first side and a second side, an outer periphery, and a central hub region extending through the first side and the second side having a bore, the first side and the second side of the support disc tapered inwardly from the outer periphery to the central hub region; a plurality of pockets staggered around the outer periphery of the support disc, each pocket opening radially outwardly and defined by a rear wall and a bottom wall, the rear wall formed within the outer periphery of the support disc and extending radially downwardly into the support disc, the bottom wall extending outwardly from the bottom of the rear wall toward the outer periphery and toward the rear of the next preceding pocket and connected to the next preceding pocket through a connecting section, a plurality of side support members, each side support member extending radially outwardly from the bottom wall to the outer periphery and laterally alternating between a first position axially offset from the second side and a second position axially offset from the first side, wherein each side support member is tapered inwardly from the bottom wall to the outer periphery, wherein the rear wall alternates between a first position extending laterally from the first side to the side support member that is offset from the second side and a second position extending laterally from the second side to the side support member offset from the first side; and a cutting insert secured in each pocket including at least one cutting edge, wherein the cutting inserts alternatingly extend from the side support member laterally outwardly beyond the side of the support disc whereby the cutting edge of adjacent inserts are positioned to laterally overlap thereby providing an increased effective cutting path width.
