DNGA150408TM-2 WBH10 CBN Turning Insert — Walter Tools, Rhombic 55° with 0° Rake

The DNGA150408TM-2 WBH10 is a CBN turning insert engineered for hard turning and finishing of hardened steels, offering robust edge stability and repeatable performance in demanding operations.

• CBN grade WBH10 for hard turning
• Rhombic 55° geometry for stable cutting
• Negative 0° rake for robust edge control
• 0.8 mm corner radius for consistent finish

Maximise process security in hard turning

The CBN cutting material in the WBH10 grade provides a high resistance to abrasive wear, which translates into longer tool life and fewer tool changes in hard machining operations. For components hardened to high hardness levels, the stable wear behaviour reduces process variability and improves reproducibility. Choosing a CBN insert designed for such conditions supports steady production rates and lowers the risk of unexpected rework, delivering measurable gains in throughput and process reliability.

Geometry that delivers a consistent surface and edge control

The Rhombic 55° shape combined with a 0° (negative) rake gives the insert a compact, rigid cutting edge that resists chipping under heavy contact loads. The 0.8 mm corner radius is optimised to balance edge strength and surface finish, enabling reliable finishing passes without sacrificing robustness. These geometric choices reduce vibration and promote predictable chip flow, which in turn helps to maintain dimensional accuracy and surface integrity during difficult passes.

Designed specifically for hardened materials

Built for the H material group (hardened steels), the insert excels where conventional carbide grades struggle. CBN is particularly suited to work hardened steels and similar hard materials because it withstands high contact temperatures and abrasive wear. For shops that run components from heat-treated batches or require consistent performance on pre‑hardened parts, this solution simplifies tool selection and secures process stability; the insert supports both hard turning and precision finishing tasks as required by the operation.

Practical benefits for production and inventory

Integrating the WBH10 CBN insert into a tooling portfolio reduces downtime associated with frequent tool changes and lowers the total cost of machining per component through extended wear intervals. The standardised rhombic format simplifies holder stocking and interchangeability, while the clear specification of geometry and grade assists in planning for predictable wear cycles. For application guidance or to confirm suitability for a specific component, in‑house technicians and Metav Werkzeuge consultants can provide cutting suggestions and material‑specific advice.

FAQ

Which materials can be machined with this insert?
The DNGA150408TM-2 WBH10 CBN turning insert is specified for hardened steels (ISO group H) and is intended for hard machining tasks where wear resistance is critical.

What does the Rhombic 55° geometry and 0° rake mean for machining?
The Rhombic 55° shape and negative 0° rake provide a rigid cutting edge and controlled chip flow, improving edge stability and helping to produce consistent surface quality with reduced risk of edge breakouts.

Is this insert suitable for finishing passes on hardened parts?
Yes, the WBH10 grade combined with a 0.8 mm corner radius is designed to support finishing and precision hard turning, offering a balance between edge strength and surface finish.

What is the WBH10 grade and why use CBN?
WBH10 is a Walter CBN grade formulated for hard and highly abrasive applications; CBN offers superior wear resistance compared with carbide when machining heat‑treated and hardened steels.

Can the insert be used on pre‑hardened steel?
The insert is suitable for pre‑hardened and hardened steels, making it appropriate for operations where components have elevated hardness levels before or after heat treatment.
