DEFINITION

Classification: 408/72

(under the class definition) Device with a tool or tool-supporting or guiding structure and structure adapted to contact the work.

(1) Note. The work-contacting structure of this and the subclasses indented hereunder usually serves to define a kinematic relationship between the tool and the work.

(2) Note. The tool-supporting or guiding structure and the work-contacting structure may be fixed together to function as a single unit. (See especially subclass 115 and this, the outdent, subclass).

SEE OR SEARCH THIS CLASS, SUBCLASS:

241, for a tool-guiding jig (or "Drill Bushing") lacking a work-contacting surface.
