TNGA160408TM-3 WBH10 indexable turning insert — Walter Tools, CBN grade for hard turning

TNGA160408TM-3 WBH10 is a CBN indexable turning insert designed for hard machining of steels and pre-hardened materials, offering a robust cutting edge and stable performance for demanding production processes.

• CBN grade WBH10 for hard turning
• Triangular 60° geometry
• 0.8 mm corner radius for robust edge
• 0° negative rake for stable cutting

Increased productivity on hardened steels through CBN technology

The combination of CBN cutting material and the WBH10 grade is optimised for high-resistance applications. CBN is a superabrasive designed specifically for hardened steels, delivering superior wear resistance compared with conventional carbide grades. This results in longer effective cutting intervals and less frequent index changes, which translates directly into higher machine uptime and improved process stability. The insert's construction supports consistent chip formation under high contact stresses, reducing the need for frequent tool interventions and helping to maintain cycle-time targets in serial production.

Geometry engineered for dimensional stability and repeatable results

A triangular 60° geometry provides three usable cutting edges per insert and a stable seating in standard toolholders; combined with the 0.8 mm corner radius, the shape balances edge strength and surface finish. The 0° negative rake offers a neutral to slightly protective cutting action that reduces edge chipping when encountering hardened zones or interrupted cuts. Explaining the terms: the corner radius increases edge robustness at the expense of some cutting force, while negative rake angles shift cutting forces into the tool body for enhanced edge security—both choices favour repeatable accuracy and longer life in heavy-duty turning tasks.

Practical benefits for production planning and cost efficiency

Because the insert is tailored for high‑wear environments, tool-change frequency is reduced and scrap rates from edge failure are minimised. The indexable design enables rapid repositioning of a fresh cutting edge without regrinding, supporting lean workflows and predictable tooling budgets. For engineering teams assessing total cost of ownership, the longer service intervals and consistent component finish offered by this CBN solution often justify the initial selection in applications where material hardness exceeds conventional turning ranges.

Application guidance and support for process optimisation

This insert is particularly suited to finishing and semi-finishing of hardened steels and pre-hardened components where dimensional accuracy and surface quality are critical. For machine setups that experience variable hardness or interrupted cuts, the stable edge geometry and CBN wear resistance help avoid sudden tool loss. If additional data is required for feed and speed recommendations or for verifying compatibility with a specific toolholder, technical consultation is available; Metav Werkzeuge can provide application advice and selection assistance to match the insert to process and material variables.
