Abstract

An annular cutter (10) has a cylindrical side wall (14) provided with cutting teeth (16) spaced circumferentially around its lower end, the inner periphery of each tooth (46) being radially relieved to provide a narrow margin(m) at the inner side of each tooth directly behind the cutting edge thereof (22) and simultaneously provide a large escape path (50) for chips and an enlarged coolant passageway.
