TNGA160408TM-3 WBH10C indexable turning insert — CBN grade for hard turning (Walter Tools)

The TNGA160408TM-3 WBH10C is a triangular 60° indexable turning insert designed for heavy-duty hard turning of hardened steels and other high-wear materials, offering a negative 0° rake for robust machining.

• CBN grade WBH10C for heavy wear resistance
• Triangular 60° shape for versatile turning
• 0.8 mm corner radius for consistent edge strength
• Negative 0° rake for robust and stable cuts

High wear resistance that extends tool life and stabilises cycles

The coated CBN grade WBH10C is formulated for the demands of hard machining and delivers exceptional wear resistance when machining hardened steels (designation H). This material choice reduces flank wear and extends edge life under high contact stresses, which in turn increases process uptime and lowers tooling consumption per component. For production environments where repeatability and predictable tool change intervals matter, the combination of a wear-resistant cutting grade and stable geometry contributes directly to more consistent cycle times and fewer unscheduled interventions. The insert designation is optimised for applications that require controlled tool life and dependable performance.

Geometry and edge design for secure cutting and chip control

The triangular 60° configuration and the 0.8 mm corner radius produce a stable cutting edge that tolerates moderate interrupted cuts without rapid edge deterioration. The negative 0° free angle creates a robust cutting face that resists edge chipping under high radial loads, while the specified chipbreaker index 3 supports orderly chip formation in hard materials. Together, these features mean improved surface integrity and reduced rework. Operators and process planners will find the geometry useful where mechanical stability is required, particularly on hard-turning operations where cutting forces and heat generation are elevated.

Practical integration: process security and handling benefits

Designed as part of the Walter CBN / hard material series, this insert is supplied to established ISO designation standards and tolerance class G, enabling straightforward toolholder compatibility and predictable indexing. The plate size code indicates a 16-series geometry with a thickness code 04, making it suitable for common turning toolholders that accept TNGA-style inserts. The robust specification simplifies tool inventory management and supports quick tool changes during production. Technical teams prioritising process security and reproducible component quality will value the balance of a specialised CBN cutting grade and standardised insert form, which together promote stable machining and efficient integration into existing turning cells.

FAQ

What materials is this insert suited for?
The insert is intended primarily for hardened steels (H); the WBH10C CBN grade of this Walter Tools turning insert is optimised for hard machining tasks and offers high wear resistance for such materials.

How does the 0.8 mm corner radius affect machining?
A 0.8 mm corner radius provides improved edge strength and surface integrity during turning; the geometry reduces the risk of edge chipping in harder materials while supporting stable cutting conditions.

Is the insert compatible with standard TNGA toolholders?
The designation TNGA160408TM-3 indicates compatibility with holders designed for TNGA-style triangular 60° inserts; tolerance class G and the standard form support straightforward integration into compatible toolholder systems.

What advantages does the negative 0° rake deliver?
The negative 0° rake increases the robustness of the cutting edge and improves stability under high cutting forces, which is beneficial in hard-turning operations where mechanical loads and temperature are elevated.

Does the WBH10C grade require any special cutting parameters?
The WBH10C CBN grade is engineered for hard materials and typically demands process parameters tuned for lower cutting speeds and stable feeds appropriate to hardened steels; for exact parameter guidance, consult Metav Werkzeuge or the application specialists.
