WNMG060408-MU5 WSM20S indexable turning insert — Trigon 80°, for stainless steels and superalloys — Walter Tools

A WNMG060408‑MU5 WSM20S indexable turning insert designed for secure chip formation and long tool life when machining tough, heat‑sensitive materials such as stainless steels (ISO group M) and heat‑resistant superalloys (ISO group S).

• Tiger‑tec Silver coated carbide WSM20S
• MU5 chipbreaker for secure chip control
• Trigon 80° geometry, 0.8 mm nose radius
• 0° (negative) relief for robust cutting edges

Optimised cutting performance for demanding materials

The combination of the Tiger‑tec Silver coating and the WSM20S carbide grade is engineered to resist heat and reduce flank adhesion when machining stainless steels and superalloys. The coating increases thermal resistance and lowers friction at the cutting zone, which supports stable cutting edges and longer tool life. For operators and production planners, this means fewer index changes, more consistent component quality and reduced downtime in serial turning operations. The insert’s suitability for ISO groups M and S is reflected in the substrate and coating design, which together promote controlled wear rather than catastrophic edge failure.

Geometry and chip control that protect surface finish and productivity

The Trigon 80° shape with a 0.8 mm corner radius and the MU5 chipbreaker deliver a balance between edge strength and chip segmentation. The negative 0° relief angle enhances edge robustness, making the insert less prone to chipping under interrupted cuts or heavy cross‑sections. The MU5 chipbreaker is optimised to form short, controllable chips in tough alloys, which reduces the risk of entanglement and improves safety at the machine. Improved chip control also helps maintain a consistent surface finish and reduces the need for secondary operations.

Practical benefits for workshop efficiency and process reliability

As a coated, indexable solution, the insert simplifies inventory and tool management: stock of one grade covers a broad range of stainless and heat‑resistant materials, while the standard WNMG format allows fast seat changes in compatible holders. The design supports predictable tool wear, which aids tool‑life planning and cost forecasting in production. For projects requiring process assurance, the combination of coating technology and geometry contributes to repeatable results, lower scrap rates and higher throughput — attributes that matter in small‑batch and large‑scale turning alike.

FAQ

What materials is this insert best suited to machine?
The WNMG060408‑MU5 WSM20S insert is optimised for stainless steels (ISO M) and heat‑resistant superalloys (ISO S); the Tiger‑tec Silver coating and substrate enable good heat resistance and stable cutting under the conditions typical for these groups.

How does the MU5 chipbreaker affect machining?
The MU5 chipbreaker on the insert promotes short, manageable chips and improved evacuation during turning operations, which supports surface quality and reduces the risk of chip interference at the tool tip.

Can the Trigon 80° form deliver good edge strength for interrupted cuts?
Yes — the trigon geometry combined with a 0.8 mm nose radius and the negative 0° relief enhances edge robustness, making the insert suitable for operations with intermittent engagement or heavier cross‑sections.

Is this insert compatible with standard WNMG tool holders?
The WNMG format conforms to the common WNMG seat dimensions; compatibility depends on the specific holder and clamping system, but the insert follows standard WNMG codes for straightforward replacement.

What benefits does the Tiger‑tec Silver coating provide?
Tiger‑tec Silver increases thermal resistance and reduces friction at the cutting interface, which helps to limit built‑up edge and extend edge life when machining tough, heat‑sensitive materials.
