WNGA080404SM-S WCH10C — Trigon 80° indexable turning insert for hardened steels, Walter Tools

A WNGA080404SM-S WCH10C indexable insert designed for hard turning and high-temperature, high-speed applications in hardened steel machining

• Coated ceramic grade WCH10C for hard turning
• Trigon 80° form for stable cutting
• 0.4 mm corner radius for reliable edge strength
• Negative 0° rake for heavy-duty cuts

Precision and productivity where hardness demands performance

The insert is designed around a coated ceramic cutting grade that excels in high-temperature, high-speed conditions typical of hard turning. The combination of a trigon 80° geometry and a negative 0° rake produces a robust cutting edge that reduces plastic deformation and extends tool life when machining hardened workpieces. This results in fewer tool changes and a more predictable production rhythm, improving overall process efficiency and lowering machining costs.

Why the geometry matters for repeatable results

The trigon 80° shape concentrates cutting forces into a controlled contact area, enhancing rigidity and enabling deeper cuts where required. The corner radius 0.4 mm contributes to a stronger cutting edge that resists chipping during interrupted cuts or hard material sections. These geometrical choices translate into stable chip formation and consistent surface finish, making the insert suitable for demanding sequential production tasks on hardened steels.

Material compatibility and application focus

The cutting grade is specified for the ISO material group H and is therefore tailored for hardened steels and pre‑hardened components. As a member of the Walter CBN / hard material series, the insert supports operations where wear resistance and thermal stability are critical. For shops converting from conventional carbide to ceramic‑based grades, this insert offers an effective balance between high cutting speed capability and predictable wear behaviour, provided cutting data is adapted to the workpiece hardness.

Practical handling and process support

The insert's design simplifies adaptation into existing toolholders and turning routines: the solid geometry minimises fixturing adjustments and the consistent edge profile aids process set‑up. For best results, pair the insert with cutting conditions optimised for ceramic grades and consult recommended parameters for speed and feed; engineering support from Metav Werkzeuge is available to supply tailored cutting data and trial recommendations. This practical support helps integrate the insert into production while mitigating the learning curve for advanced cutting materials.

FAQ

What materials is this insert intended for? The WNGA080404SM-S WCH10C insert is specified for ISO group H and is intended primarily for machining hardened steels and similar hard materials.

How does the 0.4 mm corner radius affect cutting performance? A corner radius of 0.4 mm increases edge strength and reduces the risk of chipping, improving stability during interrupted cuts and when machining hardened surfaces.

Is this grade suitable for high cutting speeds? Yes, the WCH10C coated ceramic grade from the Walter CBN / hard material series is optimised for higher cutting speeds and thermal stability in hard‑turning applications.

Can the insert be used in standard toolholders for trigon inserts? The insert’s trigon 80° form is compatible with standard holders designed for trigon inserts; mounting specifics depend on the holder type and clamping system used.

Where can cutting data and process recommendations be obtained? Cutting parameters and application guidance are available from Metav Werkzeuge; technical consultation will help adapt speeds and feeds for the workpiece hardness and machining strategy.
