Carbide Grades Two types of standard coatings are available:
IC07 grade is the basic substrate for the reaming • IC907 – a TiAlN PVD coating for steel (P) and
inserts. It is a very versatile submicron grade. stainless steel (M) workpiece material groups
IC07 features very high fracture toughness and • IC507 - a TiCN+TiN PVD coating for cast iron (K)
wear resistance, which is required for efficient workpiece material group
high speed reaming.
An uncoated IC07 can be used for machining The following grades can be provided on request:
nonferrous (N type material group) applications. • PCD grade for machining aluminum
• PCBN grade for machining cast iron
• IC30N (cermet) for machining steel
