Applications
These round indexable inserts are a well-thought-out choice for CNC milling machines and conventional milling systems. They are ideally suited for the medium machining of structural steel, tool steel, and cast iron. Due to the circular cutting edge, the inserts can also be used flexibly for profiling and copy milling operations.
Special features
The RT300 cutting material stands out with its PVD coating, which is specifically designed for wear protection in universal steel applications and stainless steel machining within the P15-P25 and M10-M25 range. The precise round inserts (0803, 10T3, 1204) offer high adaptability to different tool holders and milling strategies. The stable design reduces vibrations, which can have a positive effect on tool life and optimize the surface finish on the workpiece.
