The ISO 13399 series is an application of the ISO 10303 and ISO 13584 standards for the computerised representation and exchange of cutting tool data. ISO 13399-1, conforming to ISO 10303, is a specification for the representation of the items and their assembly in a modern cutting tool.

The descriptions and the properties of the items are defined in the digital dictionary, conforming to ISO 13584, and these item terms and property names are used by ISO 13399-1. Manufacturers, buyers and users can use ISO 13399-1 and the digital dictionary to store cutting tool data and to exchange this data in an unambiguous way.

The ISO 13399 Maintenance Agency provides for the update of the dictionary to take into account: experience, feedbacks, and user's needs.

ISO has appointed AFNOR/UNM, the secretariat of the committee ISO/TC 29 Small tools, for the installation, the hosting and the management of the maintenance agency.
