DNGA150608TM-2 WBH20 — Indexable turning insert for hardened steels | Walter Tools

The DNGA150608TM-2 WBH20 is a CBN indexable turning insert designed for hard machining tasks, offering a rhombic 55° shape and a robust cutting grade for use on hardened steels.

• CBN grade WBH20 for hard turning
• Rhombic 55° profile for versatile clamping
• 0.8 mm corner radius for controlled cutting
• 0° negative rake for stable engagement

High-performance grade for demanding hard machining

The combination of CBN technology and the WBH20 grade provides exceptional wear resistance and edge stability when machining hardened materials. CBN is specifically developed for tasks where conventional carbide struggles: high hardness, elevated cutting forces and abrasive wear are typical in such processes. This results in fewer tool changes, extended periods between indexings and more predictable component quality, which directly supports higher machine utilisation and reduced process costs.

Geometry that ensures consistent results and surface quality

The Rhombic 55° form paired with a 0.8 mm corner radius and 0° negative rake promotes controlled cutting engagement and stable chip formation. The modest corner radius helps maintain finish while distributing cutting forces to protect the edge, and the negative rake enhances edge strength for interrupted or heavy cuts. The included chipbreaker 2 aids in consistent chip control, reducing the risk of problematic evacuations and improving repeatability in serial production.

Productivity advantages and economic benefits

Using a CBN insert such as this lowers overall machining cost per part through extended tool life and consistent cutting behaviour on hardened steels and pre‑hardened components. The WBH20 grade, developed for hard materials, supports stable wear patterns and predictable regrinding intervals where applicable. Economies arise from fewer tool changes, more stable cycle times and improved surface integrity that can reduce downstream finishing operations.

Practical application and process integration

The insert is intended for stable clamping in suitable indexable holders and benefits from rigid machine setups. Its tolerance class G and standard DNGA geometry allow integration into established toolholder systems for turning operations focused on hard and pre‑hardened steels. When implementing the insert, ensure appropriate cutting parameters for CBN tooling and verify coolant strategies where applicable; the result is a reliable, repeatable hard‑turning process that supports quality-critical production.
