Abstract

The tool shank (2) has a forked end to carry a cutter disc (1). The latter consists of two identical cone sections (3, 4) with a common circular joint line (C). Each cone has a cutting surface (F, F'), being symmetrically located on each side of axis (X-X'), and meeting at a common point (H) on this axis. The cutting surfaces are formed by chords on the circle (C); a small angle being formed between the chords. The disc pref. has a central hole used to mount it between the forks on the shank. The tool is for use in the aviation and automobile industries for accurate milling operations.
