Title: COMPOUND FILLET RADII CUTTER
Abstract:
A compound fillet radii cutter may have a shaft having a cylindrical member, frustoconical cutting surface, a small radius cutting surface having an arc length of a first circle, and a large radius cutting surface having an arc length of a second circle. The frustoconical cutting surface may be disposed between the cylindrical member and the small radius cutting surface. The small radius cutting surface may be disposed between the frustoconical cutting surface and the large radius cutting surface, and a juncture of the large radius cutting surface and the small radius cutting surface may form a tangential union. In this manner, a single cutter may cut radii of various sizes or cut compound radii.
