Lead angle 0°/ 2° MEC/MECX When using inserts with corner-R(RE) 1.6 or larger, additional modifications of the cutter body will be necessary. Ref. to the chart below for the recommended modifications. (Additional grind off is not necessary when corner-R(RE) is 1.2 mm or less.) * Round- shaped additional processing is recommended.
