This invention relates to apparatus for trimming and shape cutting a hearing aid having a three-dimensional body of irregular shape and a flat plate-like member surface mounted against the body for forming an enclosure in which electronic circuitry is mounted. The flat plate-like member has a rim of excess material extending from the body of the hearing aid. The apparatus includes a framework extending from a base with a surface plate mounted on the framework. A rotary drive is connected to the framework with a tool bit extending through an opening in the surface plate. A guide member having a finger is attached to the surface plate with the finger extending over the opening above the rotary tools bit, leaving a space in which the rim of the flat plate-like member is placed for automatic removal.
