​ISO 13399 Terminology 
(download terminology chart)

Previous to 2019, we classified our tools according to WMG (Workpiece Material Groups) and AMG (Application Material Groups). We have unified our technical data formats to only use WMG.
WMG support easy and reliable selection of the right cutting tool and starting values for machining conditions in particular applications. Dormer Pramet classifies workpiece materials into ISO groups, sub groups and material properties.

More information on this classification system can be found in the download.
​​ISO 13399 is an international cutting tool information standard. It provides dimensions and parameters in a neutral format that is independent of any particular system or company nomenclature. When cutting tools are clearly defined according to a global standard, all types of software can process the electronic data more quickly, improving the quality of communication and helping to make the exchange of information run smoothly.

Dormer Pramet began aligning all of its product data and catalogs with ISO 13399 in November 2019.
