The CoroCut 2 parting blades are upgraded with internal coolant and an improved clamping finger design, which offers a higher clamping force and better side stability. Tool holders with precision coolant are updated with a screw clamp solution, which keeps insert movement to a minimum without any loss of clamping force. Other features included in the upgrade are new and updated grades and geometries, including the new first choice grade GC1225, a wiper design for all parting geometries and an enhanced edge line quality on all inserts.
