Where: M-type Tools Kc - Specific cutting forces (N/mm M-type tools have no support under the insert’s 2), turning values could be used cutting edge
h - Efficiency (h≈0.8) For an insert with a width smaller than 2.2 mm,
there are no standard catalog tools available. Kc Values There are 2 options as to how to use these

1. Modify an existing tool and adjust the support
pulley-V inserts and various specially tailored inserts) and therefore the above explanation should be considered
same tool (up to 6.4 mm) to little support and limited gripping forces
