System tools, i.e. those that can be used universally for numerous machining requirements, reduce the complexity of and susceptibility to errors in production, thus making it more cost-efficient.

The latest example of this product philosophy from Walter AG is the new M4000 range with system indexable insert. Walter has consistently implemented the idea of a system concept: The new inserts and cutting bodies are manufactured in a way that offsets CO2 emissions. The M4000 – four square indexable inserts that can be used in three different types of milling cutters and master many common milling operations: For example, face milling, shoulder milling or chamfering in all steel, stainless steels, cast iron, and even difficult-to-cut materials.

M4000 inserts can therefore be used more universally than their specialised relatives in the Walter BLAXX and Walter Xtra▪tec® ranges. However, just like its two cousins, it is coated with the high-performance cutting material Tiger•tec Silver®. What are the features of the system indexable inserts for the M4000? The flank faces on the four cutting edges are provided with a wave profile, which displays the geometry of the indexable insert: The more waves that are visible, the more positive the geometry. Currently the stable (D57) and universal (F57) geometries are available.​
