VBGW110304TM-2 WBH20 indexable turning insert — Walter Tools, CBN grade for hard turning

The VBGW110304TM-2 WBH20 is an indexable turning insert in rhombic 35° form, engineered for hard turning and robust performance when machining hardened steels.

• CBN grade WBH20 for hard turning
• Rhombic 35° geometry for versatile cuts
• 0.4 mm corner radius for precise finishing
• 5° relief angle with chipbreaker 2

Reliable cutting performance for hardened materials

The insert combines a CBN cutting grade (WBH20) with a geometry tailored to hard machining, delivering high wear resistance and prolonged tool life. Cubic boron nitride is significantly harder than carbide and therefore maintains a stable cutting edge under the high temperatures and forces typical of hardened steel work. This results in fewer indexings, reduced tool change frequency and consequently higher component throughput — a clear efficiency advantage for production environments where uptime and repeatability matter.

Geometry that enhances surface finish and chip control

The rhombic 35° shape and 0.4 mm corner radius offer a balance between access to tight profiles and an appropriately small nose for fine finishing. The 5° relief angle reduces rubbing and improves shearing, while the integrated chipbreaker 2 promotes controlled chip formation even in demanding steels. Together these features support consistent surface quality and lower secondary finishing effort, which helps maintain cycle-time targets and reduces downstream processing.

Application fit and material compatibility explained

Designed for ISO group H applications, the grade is specifically specified for hardened steels and is suitable for pre-hardened material where wear resistance is essential. The WBH20 grade, part of the Walter CBN / Hartstoff series, is targeted at hard and strongly abrasive machining tasks; explanation of the term CBN clarifies why it is preferred for these applications — exceptional hardness and thermal stability compared with conventional carbides. For shops facing recurring hard turning or finishing of heat-treated components, the insert offers process security and predictable performance.

Practical integration and production benefits

With the designation VBGW110304TM-2 WBH20, the insert matches established tooling systems and inserts of similar numbering, enabling straightforward integration into existing toolholders. Its tolerance class G supports reproducible positioning and consistent clamping behaviour at changeovers. The nominal size value 11 and thickness 03 make it suitable for many standard turning bodies, while the combination of CBN grade and chip control reduces tool inventories through longer individual insert life. The result is a measurable reduction in downtime and an improvement in total machining economy.

FAQ

What materials is this insert suitable for?
The VBGW110304TM-2 WBH20 insert is intended primarily for hardened steels (ISO group H); the WBH20 CBN grade delivers wear resistance and edge stability for such applications.

How does a CBN grade differ from carbide for turning tasks?
CBN grades such as WBH20 provide higher hardness and thermal stability than carbide, which makes the insert better suited for hard turning and maintaining surface finish under elevated cutting temperatures.

Can the insert be used in standard toolholders?
Yes, the insert follows a familiar indexable geometry and sizing; the designation VBGW110304TM-2 corresponds to common toolholder interfaces, allowing straightforward integration with appropriate turning bodies.

Which applications benefit most from this Walter Tools insert?
Applications involving finishing or continuous turning of hardened and pre-hardened steels benefit most, where the WBH20 grade reduces tool change frequency and supports consistent part quality.
