TNGA160404TM-3 WBH20 indexable turning insert — CBN grade for hard turning, Walter Tools

A TNGA160404TM-3 WBH20 indexable turning insert engineered for hard and highly wear‑resistant machining tasks, offering a triangular 60° geometry and CBN cutting material for reliable performance in hardened steels.

• CBN grade WBH20 for hard turning
• Triangular 60° geometry for versatility
• 0.4 mm corner radius for fine finishing
• 0° negative rake for a robust cutting edge

Exceptional wear resistance for hardened steels

The combination of CBN grade WBH20 and a purpose‑built insert geometry provides significantly improved resistance to abrasive wear when machining hardened steels. CBN is a superabrasive designed for the high contact temperatures and forces typical of hard turning; as a result, the insert maintains a stable cutting edge over extended cycles, reducing the frequency of tool changes and contributing directly to more predictable cycle times and lower process cost per component.

Robust geometry that supports stable machining

A 60° triangular form with a 0° negative rake delivers mechanical strength at the cutting edge, allowing more secure interruption tolerance and heavier depths of cut where process stability is essential. The 0.4 mm corner radius balances edge strength with surface quality, producing consistent finishes without sacrificing edge life. The insert’s dimensions and chip‑forming features ensure reliable chip control even under demanding conditions, which is crucial for unattended or lights‑out machining strategies.

Process benefits and application guidance

Designed specifically for hard turning applications, the insert supports efficient material removal from pre‑hardened and hardened steels while preserving dimensional stability. The graded composition prioritises stable chip formation and repeatable results across batches, making it suitable for series production and repair work on hardened components. For best results, pair the insert with compatible turning toolholders and adapt cutting parameters to account for the high thermal loads associated with CBN machining.
