WNMG080412-MM5 WSM30S trigon 80° turning insert — negative rake, 1.2 mm corner radius (Walter Tools)

A WNMG080412-MM5 WSM30S turning insert designed for heavy‑duty machining of stainless steel and superalloys, delivering stable chip control and extended tool life in demanding production environments

• Tiger‑tec Silver coated carbide grade WSM30S
• Trigon 80° form with 0° negative rake
• MM5 chipbreaker for secure chip formation
• 1.2 mm corner radius for robust cutting edges

Reliable performance for stainless steel and superalloys

The Tiger‑tec Silver grade WSM30S is a coated carbide solution developed for difficult‑to‑cut materials. Its coating and substrate combination promote stable chip formation and resist rapid wear when turning stainless steel (ISO M) and heat‑resistant superalloys (ISO S). This results in more predictable tool life and fewer unexpected tool changes, which supports continuous production and reduces process downtime. The MM5 chipbreaker is tuned to favour short, controllable chips under interrupted or continuous cuts, improving operator safety and machine cleanliness.

Geometry engineered for productivity and edge security

The Trigon 80° configuration with a 0° negative rake provides a secure cutting geometry for heavy engagement and interrupted cuts; it reduces the tendency for edge chipping when cutting tougher alloys. A 1.2 mm corner radius increases the effective edge strength while maintaining an acceptable surface finish on the workpiece. In practice, this geometry enables higher metal removal rates without sacrificing repeatability, making the insert suitable for roughing and semi‑finishing operations where cutting‑edge stability and robustness are priorities.

Practical benefits and easy process integration

As a standard indexable insert form, the item fits common WNMG toolholders and integrates into established turning setups without special tooling changes. The coated grade supports elevated cutting parameters, which can shorten cycle times and increase throughput — a clear cost‑efficiency argument in production planning. For engineers and shop floor planners, the insert’s combination of chip control, edge durability and a proven coating system translates into fewer tool inventory variants and simpler process parameter selection.

Application guidance and safety considerations

When machining stainless steel and superalloys with this insert, use stable clamping and appropriate cutting fluids where specified by the machine or workpiece supplier to manage heat and lubrication. The MM5 chipbreaker assists with short chip formation; however, machining parameters should be validated on representative parts to confirm chip behaviour and surface finish. Where possible, monitor machining forces during initial trials to fine‑tune feeds and speeds for optimal balance between productivity and tool life.

FAQ

Which materials is this turning insert suitable for?
The WNMG080412‑MM5 WSM30S insert from Walter Tools is designed primarily for stainless steel (ISO M) and for heat‑resistant superalloys and titanium (ISO S), offering secure chip control and thermal stability.

What are the main benefits of the Tiger‑tec Silver WSM30S grade?
Tiger‑tec Silver in the WSM30S grade provides a balanced coated carbide system that enhances cutting‑edge stability and wear resistance, which can extend tool life and support higher cutting parameters in demanding materials.

How does the MM5 chipbreaker affect machining?
The MM5 chipbreaker produces short, controllable chips under typical turning conditions, improving machine hygiene and operator safety while maintaining consistent surface quality in roughing and semi‑finishing operations.

Is the Trigon 80° form suitable for interrupted cuts?
Yes — the Trigon 80° geometry combined with a 0° negative rake and a 1.2 mm corner radius increases resistance to edge chipping, making this insert well suited for interrupted cuts and heavy engagement typical in roughing.

Can the insert be used in standard WNMG toolholders?
The WNMG080412‑MM5 WSM30S uses the common WNMG geometry and fits standard toolholders for that form; initial parameter validation on representative parts is recommended to confirm optimal performance.
