VBGW160404TM-2 WBH20C indexable turning insert — CBN grade, rhombic 35°, Walter Tools

VBGW160404TM-2 WBH20C is a rhombic 35° indexable insert engineered for hard turning and heavy-duty finishing of hardened steels.

• Walter CBN grade WBH20C for hard materials
• Rhombus 35° geometry for versatile turning
• 0.4 mm corner radius for reliable edge strength
• 5° clearance angle for controlled chip flow

Robust wear resistance for hard turning applications

The insert VBGW160404TM-2 WBH20C is produced in a CBN-based grade specifically developed for severe wear conditions encountered in the machining of hardened steels. Cubic boron nitride provides a stable cutting edge at elevated temperatures and under high contact pressures, which translates into a longer effective tool life and fewer tool changes per shift. This stability supports consistent cycle times and reduces unexpected stoppages, making the component a rational choice where process reliability and repeatability are priorities.

Geometry that supports chip control and surface quality

With a rhombic 35° form, a 0.4 mm corner radius and a 5° clearance angle, the geometry promotes controlled engagement and predictable chip flow. The defined corner radius increases edge strength for interrupted cuts while the modest clearance angle helps maintain a stable cutting contact to reduce vibration. The integrated chipbreaker 2 assists in producing shorter, manageable chips and contributes to improved surface finish, lowering the need for secondary operations and enhancing overall process efficiency.

Designed for productive, reproducible machining

The combination of a CBN cutting material and precise geometry delivers measurable productivity benefits: higher material removal rates in hard-turning tasks and reduced tooling costs via extended insert life. The insert’s classification and tolerance align with industrial expectations for repeatable performance, which supports planning and tool inventory management. For production environments where cycle consistency and predictable consumable behaviour are essential, this solution offers a clear cost-benefit through reduced downtime and stable product quality.

Practical handling and application notes

The insert is supplied in the Walter CBN / Hartstoff series and is intended for machining pre-hardened and hardened steels according to the material group designation. Mounting in standard compatible toolholders with the corresponding pocket geometry yields secure clamping and correct rake/clearance orientation. The tolerance class contributes to interchangeability across assemblies. For application-specific suggestions, including recommended feed and depth strategies for different hardness levels, technical consultation is available to align machining parameters with shop-floor realities.

FAQ

What materials is this insert suitable for?
This indexable insert is designed primarily for hardened and pre-hardened steels; the CBN grade WBH20C gives the insert high resistance to abrasive wear when machining hardened materials.

How does the rhombic 35° geometry affect cutting performance?
The rhombic 35° shape offers a versatile cutting edge that balances access and strength, and when paired with the 0.4 mm corner radius it provides stable performance for both finishing and more demanding interrupted turning operations.

Is this insert compatible with standard toolholders?
Yes, the VBGW160404TM-2 WBH20C is intended for use in toolholders compatible with the specified indexable insert form and size; correct pocket fit and clamping ensure consistent cutting geometry.

What benefit does the WBH20C grade give compared with conventional grades?
The WBH20C grade, containing CBN, significantly improves edge retention and thermal resistance in hard-turning tasks, leading to extended tool life and steadier machining performance under high contact loads.

Can this insert be used on castings or non-ferrous alloys?
The insert is optimised for hard and pre-hardened steels; alternative grades should be selected for cast irons or non-ferrous alloys to achieve optimal chip formation and tool life.
