WNMG080408-MW5 WMP20S Drehwendeschneidplatte — Trigon 80°, 0° negative rake (Walter Tools)

WNMG080408-MW5 WMP20S is a trigonal indexable turning insert designed for robust performance when machining rostfreier Stahl in medium to heavy conditions

• Trigon 80° geometry for stable turning
• 0° negative rake for secure edge engagement
• 0.8 mm corner radius for chip strength
• Tiger·tec Silver coated, WMP20S grade

Consistent machining performance for rostfreier Stahl

The combination of the Tiger·tec Silver coating and the WMP20S grade provides a balanced solution for machining rostfreier Stahl where toughness and thermal loads are high. The coated carbide substrate delivers a coated carbide structure that reduces adhesive wear and supports a stable cutting edge under intermittent and continuous cuts. With the trigonal form and a 0° negative rake, the insert resists edge deformation and reduces the risk of built-up edge formation, which is critical when turning materials that tend to work-harden. This results in predictable process behaviour and reduced scrap rates during serial production.

Controlled chip formation and improved tool life

Equipped with the MW5 chipbreaker, the insert promotes controlled chip segmentation and evacuation at a wide range of cutting conditions. The chip geometry supports consistent chip flow even when feeds and depths vary, reducing manual intervention and downtime. The 0.8 mm corner radius increases the effective cutting edge thickness, improving resistance to mechanical overload and extending edge life. For workshops prioritising uptime and repeatability, these features combine to lower tooling change frequency and improve overall throughput.

Geometry and handling benefits for turning operations

The Trigon 80° shape provides secure seating and stable cutting forces, particularly advantageous for medium to heavy turning where axial engagement is significant. The 0° negative rake gives predictable cutting behaviour and simplifies insert choice across different applications, while the compact insert size supports fine step-downs and finishing passes without sacrificing robustness. The insert family’s standardised form factor eases toolholder stocking and replacement, helping maintain a lean tooling inventory.

Application guidance and process advantages

This insert is specified for machining rostfreier Stahl according to the WMP20S designation: a coated carbide grade optimised for the challenges of these materials. In practice, the insert delivers a compromise between wear resistance and toughness, making it suitable for customers seeking consistent surface quality and reliable tool life under mixed turning conditions. For setups requiring process stability and reduced operator adjustments, the combination of Tiger·tec Silver technology and the MW5 geometry offers measurable improvements in production consistency and component finish.
