Abstract:
1. A tool body for face milling, peripheral milling, ramp milling, and helical interpolation, comprising: a shank, a working end opposite said shank, a pocket for receiving a cutting insert having at least two cuffing edges for face milling, peripheral milling, ramp milling and helical interpolation, a radial clearance face, the radial clearance face having a diminishing radius, and a flute defined by a bottom, said flute being graduated so that said bottom moves further away from a central, longitudinal axis of said tool body in a radial direction as said flute extends toward said shank and away from said working end of said tool body, thereby increasing a cross-sectional area of said tool body and adding rigidity to said tool body.
