SCMT120408‑MM4 WMP20G indexable insert for turning and drilling – Tiger‑tec Gold grade, 0.8 mm nose radius (Walter Tools)

The SCMT120408‑MM4 WMP20G is a square 90° indexable insert designed for turning and drilling/boring operations, optimised for machining rostfreier Stahl under medium to robust cutting conditions.

• Tiger‑tec Gold coating for enhanced wear resistance
• Optimised chip control MM4 for rostfreier Stahl machining
• 0.8 mm corner radius for consistent surface finish
• Square 90° form for versatile turning operations

Extended tool life through advanced Tiger‑tec Gold coating

The Tiger‑tec Gold grade WMP20G combines a coated cemented carbide substrate with a sophisticated PVD/CVD‑style multilayer to resist edge wear and thermal loading. This results in improved tool life and more predictable cutting performance when working with tough, heat‑generating materials such as rostfreier Stahl. The coating supports stable edge retention even at elevated speeds, reducing downtime for insert changes and contributing directly to process efficiency.

Predictable chip formation and secure machining with MM4 chipbreaker

Equipped with the MM4 chipbreaker geometry, the insert promotes controlled chip segmentation and evacuation in interrupted or continuous cuts. For components in rostfreier Stahl, which tend to produce long, stringy chips, this geometry reduces the risk of built‑up edge and workpiece surface damage. The result is a safer machining cycle and fewer secondary operations, improving throughput on serial production runs.

Consistent surface quality from a defined corner radius and square form

The 0.8 mm corner radius ensures a repeatable contact geometry that supports consistent surface finish while providing edge strength for interrupted cuts. The square 90° form offers four usable edges, which increases economy per insert and provides flexibility in turning and boring tasks. Together, the defined radius and form help to maintain dimensional accuracy and surface integrity on critical assemblies.

Application guidance and material compatibility for reliable results

This insert is specified for machining rostfreier Stahl according to its grade characteristics; the substrate and geometry are chosen for medium to robust cutting conditions. For highest efficiency, pair the insert with stable toolholding, appropriate feed values for the 0.8 mm nose radius, and coolant strategies that control temperature and chip evacuation. If uncertain about feeds, speeds or tooling combinations, seek tailored advice to avoid overloading the cutting edge and to achieve repeatable productivity.
