WNGA080408SM-S WCH10C turning indexable insert — Trigon 80°, WCH10C, Walter Tools

A WNGA080408SM-S WCH10C insert engineered for hard turning and finishing of hardened steels, featuring a temperature‑resistant coated ceramic grade and a Trigon 80° geometry for stable clamping.

• Coated ceramic grade WCH10C for high-speed turning
• For hardened steels (ISO group H) and pre-hardened steels
• Trigon 80° geometry for secure seating
• Corner radius 0.8 mm and 0° negative rake

Maximise machining performance on hardened components

The WCH10C grade belongs to the Walter CBN / hard‑material series and is a coated ceramic cutting material optimised for elevated cutting speeds and thermal stability. When machining hardened steels, such alloys demand exceptionally wear‑resistant grades; the coated ceramic composition maintains edge integrity under high temperatures, reducing the frequency of insert changes. This results in a more predictable tool life and steadier cycle times, improving throughput on process‑critical parts.

Geometry that enhances stability and surface finish

A Trigon 80° profile delivers a robust seating interface in standard toolholders, while the corner radius 0.8 mm balances edge strength with achievable surface finish. The 0° negative rake offers a conservative cutting geometry that resists chipping in interrupted cuts and tough material transitions. Together these features support consistent surface quality and minimise the risk of premature edge failure, which benefits shops aiming for repeatable tolerances and low rework rates.

Designed for production reliability and cost efficiency

Tolerance class G and a standard plate size/thickness pairing ensure compatibility with common clamping systems and toolholders, simplifying inventory management. The coated ceramic chemistry of the grade supports high material removal rates on hard workpieces, meaning fewer tool changes per component and lower indirect tooling costs over a production run. In short, the insert is optimised to increase productivity in hard‑turning applications without sacrificing component quality.

Practical application advice and process considerations

This indexable insert is intended primarily for machining hardened steels and pre‑hardened materials; the chipbreaker type S assists with controlled chip formation under the dynamic conditions typical of hard cutting. When integrating the insert into a new process, verify clamping rigidity and cutting parameters in a short validation cycle: start with conservative feeds and use the material’s thermal characteristics to gradually increase cutting speed. For tailored cutting data or recommendations on compatible toolholders, Metav Werkzeuge consultants are available to assist.
