CNMG120408-MM5 WMP20S turning insert — negative 0° rake, Tiger·tec Silver, Walter Tools

CNMG120408-MM5 WMP20S is a precision turning insert designed for machining rostfreier Stahl under medium to robust cutting conditions

• Tiger·tec Silver coating for durability
• Optimised for rostfreier Stahl machining
• Negative 0° rake for heavy cuts
• Rhombic 80° geometry, 0.8 mm corner radius

Longer tool life and reliable cutting in rostfreier Stahl

The combination of the Tiger·tec Silver coating and the WMP20S grade offers a balanced mix of abrasion resistance and toughness that supports secure chip formation when working with rostfreier Stahl. The coating system reduces flank wear and extends usable life, while the specially developed grade manages the heat and adhesion tendencies common with these alloys. In practice this means fewer tool changes and more predictable process windows, which improves overall equipment effectiveness and reduces unscheduled downtime on the shop floor.

Stable geometry for robust turning and surface quality

The insert’s negative 0° rake and rhombic 80° shape deliver mechanical strength and versatility for a range of turning operations. A 0.8 mm corner radius increases edge stability during heavier feed rates and contributes to consistent surface finish in both roughing and semi-finishing passes. The MM5 chipbreaker is tuned to control built-up edge on ductile, high-alloy grades, turning difficult chips into manageable fragments and helping to maintain machine cleanliness and operator safety.

Application benefits and process guidance for production

As an indexable insert in the CNMG form factor, this grade is suitable for workshops and production lines that require repeatable performance on rostfreier Stahl components. The geometry supports secure clamping in standard CNMG pockets and the insert thickness ensures rigidity under interrupted cuts. Where higher process stability and longer intervals between regrinds are priorities, this insert contributes to lower unit costs and more consistent part quality. For specification matching, cutting-parameter recommendations and pocket compatibility, technical consultation is available through Metav Werkzeuge to ensure optimal integration into existing turning cells.
