TNGA160408SM-S WCH10C turning insert by Walter Tools — coated ceramic grade for hardened steels, triangular 60°

The TNGA160408SM-S WCH10C is a triangular turning insert designed for high-speed, temperature-resistant hard turning of hardened steels in industrial machining environments.

• Walter CBN / hard-material series grade
• Coated cutting ceramic for high speeds
• Triangle 60° geometry for stability
• Corner radius 0.8 mm for edge strength

Boost hard-turning productivity with a ceramic cutting grade

The WCH10C grade is a coated cutting ceramic developed for operations that demand high cutting speeds and resistance to elevated cutting temperatures. In practical terms, this means fewer tool changes and more uninterrupted machining time when processing hardened steels, which are classified under ISO group H. Ceramic grades maintain edge integrity at temperatures that would quickly degrade conventional carbides, so cycle times can be shortened without sacrificing component consistency. For production settings where throughput and reliable repeatability matter, this insert delivers measurable efficiency gains.

Geometry that secures surface quality and edge life

The triangular 60° form and 0° negative rake provide a robust cutting edge that resists chipping under high contact stresses. The corner radius 0.8 mm balances edge strength with achievable surface finish, making the insert suitable for light to medium finishing passes on hardened components. The inscribed circle of 16 mm ensures compatibility with tooling systems designed for TNGA-style inserts, while the thickness code 04 specifies the plate cross-section for clamping stability. Together these geometry choices support consistent form control and reduce the likelihood of workpiece rework.

Process security and controlled chip behaviour for hard materials

Equipped with chipbreaker type S and a ceramic-based grade, the insert promotes stable chip formation even when machining high-hardness alloys. The material combination enhances wear resistance, so insert life is extended in abrasive hard-turning applications. Because hard materials generate elevated temperatures and cutting forces, the thermal and mechanical stability of the grade reduces dimensional drift and helps maintain repeatable component tolerances over longer tool life cycles.

Practical usage notes and integration into production

This insert is intended for hard-machining tasks such as finishing and fine turning of pre‑hardened and through‑hardened components. Correct clamping in a compatible toolholder and a rigid machine setup are essential to exploit the grade’s advantages; a stable holder minimises vibration and protects the fragile ceramic edge from shock loads. For process optimisation or selection of suitable toolholder interfaces, Metav Werkzeuge provides application advice and can assist with grade-to-workpiece matching to achieve the expected productivity and surface quality.

FAQ

Which materials is this insert suitable for? This insert is designed for machining hardened steels (ISO H); the WCH10C grade and the Walter CBN / hard‑material series are optimised for high‑hardness applications.

What are the key geometric features of the insert? The turning insert features a triangular 60° shape, corner radius 0.8 mm and a 0° negative rake, which together provide a robust edge and stable cutting behaviour.

Is this grade appropriate for finishing passes on hardened parts? Yes, the coated cutting ceramic WCH10C is suited to finishing and fine turning in hard‑turning operations thanks to its temperature resistance and wear characteristics.

How does chip control work with this insert? Chip management is achieved via the integrated S chipbreaker and the ceramic grade’s tendency to promote short, controlled chips under appropriate cutting conditions.

Can this insert be reground or reused? Indexable inserts of this geometry are typically indexed for new cutting edges; refurbishment options depend on local service capabilities and should be discussed with the tool supplier or the manufacturer.
