There are 2 options as to how to use these narrow inserts: 1. Modify an existing tool and adjust the support under the insert to the required width 2. Use a standard M-type tool without support In wider widths, there are also cases where the support under the insert will disturb machining (threading inserts, pulley-V inserts and various specially tailored inserts) and therefore the above explanation should be considered These tools also provide the option for customers to use a very wide range of insert widths on the same tool (up to 6.4 mm) Machining conditions need to be light due to little support and limited gripping forces 349 GROOVE-TURN
