ISO is an international cutting tool information standard. Each cutting tool is defined by a number of these standardized ISO parameters. The standard provides cutting tool information in a neutral format that is independent of any particular system or company nomenclature. With tools that are clearly defined according to a standard that all software can process, the quality of communication gets better, and the electronic data exchange between systems runs smoothly.

The data gathering process will be more efficient and of higher quality. Ultimately, the standard saves time and provides an extra guarantee of quality. A common language is valuable from a system to system point of view, but will also make life easier for users.

Once you have an ISO compliant system, there will be no need to manually interpret data from paper catalogs and then key it into your system. Netherlands-English US.

On rectangular and parallelogram inserts , the width and length dimensions are used in place of the I. A two-digit number designates the sizes of these inserts. The first digit indicates the number of eighths of an inch in the width and the second digit indicates the number of fourths of an inch in the length of the insert.

The sixth position is a significant one- or two-digit number indicating the number of sixteenths of an inch in the thickness of the insert. It is a two-digit number carried to one decimal place when it is not a whole number: 1.

The seventh position indicates the cutting point configuration: a radius or a facet. In case of a facet, two letters are used. The second letter designates the facet clearance angle:. The eighth position is a capital letter that defines edge treatment and surface finish as follows:. The 10th position is only used if there are letters in the seventh position.

Related Glossary Terms alloys alloys Substances having metallic properties and being composed of two or more chemical elements of which at least one is a metal. Each position from 1 to 10 defines a characteristic of the insert in the following order: — Shape; — Clearance; — Tolerance class; — Type; — Size; — Thickness; — Cutting-point configuration; — Edge preparation; — Hand; — Facet size.

Tolerance class There are 14 tolerance classes that control the indexability of the inserts. Type The fourth position is a capital letter denoting differences in design of insert, such as the existence of fixing holes, countersinks and special features on rake surfaces.

Size The fifth position is a significant one- or two-digit number indicating the size of the inscribed circle I. Thickness The sixth position is a significant one- or two-digit number indicating the number of sixteenths of an inch in the thickness of the insert. Accessories Adapters Chucks.
