Abstract
A cutter ring for use in trimming printed circuit board leads and a method of forming the ring is the subject of this invention. The cutter member is of annular configuration and is provided with a central hub portion surrounding an aperture. The cutter member itself is formed from a hardened sintered carbide which can only be shaped through a prolonged grinding operation. A molded cap is formed over the hub portion to present a surface which is to be received within a tool holder such as an arbor. The molded cap is characterized by being formed from a relatively soft workable material which can be shaped through a machining operation.
