VNGA160404TM-2 WBH20 – Indexable turning insert, CBN grade for hardened steels, Rhombus 35° | Walter Tools

VNGA160404TM-2 WBH20 is an indexable turning insert engineered for hard‑material machining, suited to precision finishing and repeatable production work on heat‑treated components

• CBN grade for hard machining
• Rhombic 35° geometry for approach versatility
• 0.4 mm corner radius for durable edges
• Negative 0° rake for stable cutting

Maximise productivity in hard turning

The VNGA160404TM-2 WBH20 contains a CBN‑based WBH20 grade developed specifically for high‑wear applications in hardened steels. This hard material chemistry provides markedly improved wear resistance, which reduces the frequency of index changes and supports longer uninterrupted cycles. In practice, the result is a reduced tooling cost per part and greater consistency over series production runs, helping to maintain accurate tolerances on turned components where surface integrity and dimensional stability are critical.

Stable edge geometry for consistent surface finish

The insert’s Rhombus 35° form and 0.4 mm corner radius combine to offer a robust cutting edge that resists chipping during interrupted cuts and heavy cross‑feeds. The negative 0° relief angle promotes secure cutting at high radial forces, while the defined chipbreaker 2 helps control chip formation in hard turning conditions. These geometry choices translate into a reliable surface finish and predictable tool life, allowing process planners to favour repeatability and reduced scrap rates in demanding production environments.

Application scope and process guidance

Specified for ISO group H materials, this CBN grade performs strongly on hardened and pre‑hardened steels, delivering long life where conventional carbide grades wear rapidly. The combination of a compact 16 mm size and a 4 mm plate thickness suits small to medium‑section tooling assemblies where stiffness and space are limited. For integration into existing tool systems, select a rigid toolholder suited to negative‑rake inserts and ensure correct clamp torque to exploit the WBH20 grade’s wear resistance and maintain cut stability throughout batch runs.
