Applications
This indexable insert is designed to cover a broad spectrum of milling tasks, with a clear focus on the reliable machining of steel and stainless steel components. It offers flexible application possibilities, as it performs effectively in both precision shoulder milling and roughing processes with high feeds. This dual capability supports an active reduction in tool change times.
Special features
The integration of high-feed and shoulder milling geometries establishes favorable conditions for versatile machining strategies. The resilient PVD multilayer coating ensures notable wear resistance in universal steel applications, facilitating a highly stable milling process. Additionally, the carbide classification of P10-P30 and M10-M30 provides the insert with the necessary toughness for demanding daily operations.
