LNMU 0303 AS M30 carbide milling insert is a double-sided high-feed milling insert designed for compatible high-feed milling cutters. Its four usable cutting edges provide economical indexing and help reduce tooling cost per cutting edge. The high-feed geometry is designed to support high material-removal rates while maintaining stable cutting performance.

The LNMU 0303 platform is commonly used with compatible high-feed end mills and face mills, including cutter systems using LNMU 0303 inserts.
