ISCAR is launching IC5500 – a new MTCVD grade for drilling carbon and alloyed steel (ISO P).

The new grade features a new multi-layer and special post-coating treatment to substantially prolong tool life and strengthen insert toughness, while improving operational reliability.

The new grade will be available on square inserts that are used on DR drills: 3340386 SOMX 060304-DT IC5500, 3340385 SOMX 070305-DT IC5500, and 3340384 SOMT 09T306-DT IC5500.

The inserts made from IC5500 are aimed for use only in the outer pocket of DR drills (the inner insert should be an IC908 or IC808 PVD coated insert).

The upgraded IC5500 MTCVD coating enables improved toughness, chipping resistance and thermal crack resistance, while the combination of new coating and new treatment improves overall performance and process reliability.

The coating includes a post coating treatment to reduce residual stresses and improve chipping resistance, Alpha Alumina to reduce crater wear and improve chipping resistance, a thick Al₂ O₃ to improve thermal crack resistance and an intermediate layer to enhance adhesion between the Al₂ O₃ and TiCN layer in the bonding area, improving peeling resistance. The TiCN layer improves flank wear resistance and the adhesion layer enhances adhesion with the substrate, preventing peeling during machining.

IC5500 provides an excellent solution for alloy and carbon steel drilling.
