WNMG060408-MM5 WMP20S turning indexable insert — Tiger·tec Silver coating, Trigon 80° (for rostfreier Stahl) by Walter Tools

WNMG060408-MM5 WMP20S is a Trigon 80° turning indexable insert designed for medium to robust machining of rostfreier Stahl, combining a specialised coated grade with a dedicated chipbreaker for improved process reliability

• Tiger·tec Silver coating for stable cutting
• WMP20S grade for rostfreier Stahl machining
• Trigon 80° form with 0.8 mm corner radius
• MM5 chipbreaker for predictable chip control

Stable cutting and extended edge life for rostfreier Stahl

The combination of Tiger·tec Silver coating and the WMP20S grade provides a balanced resistance to heat and wear specifically where machining rostfreier Stahl tends to generate high temperatures and built‑up edge. The coated cemented carbide substrate supports a stable cutting edge, while the coating reduces friction and enhances resistance to thermal softening. For users unfamiliar with coating technologies: the Tiger·tec Silver system applies multiple layers that protect the carbide and help maintain sharpness under elevated cutting conditions, translating into fewer insert changes and greater process uptime.

Predictable chip formation and surface quality

The MM5 chipbreaker is engineered to control chips reliably in medium to robust cutting scenarios, reducing the risk of long, tangled chips that can interrupt production. Combined with the Trigon 80° form and 0.8 mm corner radius, the geometry promotes a balanced contact between the tool and workpiece, improving surface finish and dimensional repeatability. In practice, this means fewer downstream operations and a more consistent part quality when turning rostfreier Stahl, even where material toughness can otherwise cause unstable cutting.

Rigidity and cutting stability through geometry

A 0° (negative) rake angle and the Trigon profile favour stable insertion into the cut and robust edge support, which is particularly useful when facing interrupted cuts or variable workpiece conditions. The insert’s size designation (06) and thickness (04) suit standard turning toolholders, offering mechanical stability that reduces vibration and helps maintain tolerances. For operations where fixture stiffness and tool overhang are constrained, the insert’s geometry helps preserve cutting performance and minimise the need for rework.

Practical application and process integration

This turning indexable insert is intended for production environments where machining rostfreier Stahl is frequent and predictable performance is essential. The WMP20S grade is optimised for the typical challenges of these materials—tendency to work harden and form adherent chips—so operators benefit from improved process security and consistent tool life. Compatibility with common clamping systems and standard toolholder interfaces allows straightforward integration into existing turning operations, reducing setup time and simplifying inventory management.
