TS 7680

TS 7680 is a terminology standard for jig bushes used in drilling jigs. Its purpose is to regularise the names and definitions associated with these components in design, production, and use; it is centered on technical nomenclature rather than on dimensional or performance requirements.

Why jig-bush terminology matters

In general engineering practice, jig bushes are precision guide elements that help locate and guide a drill or similar cutting tool through a jig. They support repeatable hole-making, help maintain the intended tool path, and reduce ambiguity in fixture documentation. This standard gathers the terms for that specific component family so that engineers, manufacturers, and users can refer to the same part consistently.

What the document covers

• It covers terms related to jig bushes used in drilling jigs.
• It is prepared as equivalent to ISO 4248:1978.
• It is a terminology standard, so its main function is to unify concepts and names.
• The available scope does not state material requirements, tolerances, or test methods.

A terminology standard like this is especially useful in drawings, catalogues, manufacturing papers, and maintenance communication. Where terms such as bush, jig bush, guide bush, and related expressions may be used differently across organisations, a standardised vocabulary reduces misunderstanding and supports consistent technical communication. The value of TS 7680 lies in that shared language.
