VNGA160404TM-2 WBH30 indexable turning insert — CBN grade for hard machining (Walter Tools)

The VNGA160404TM-2 WBH30 is a rhombic 35° indexable insert designed for intensive machining of hardened materials, offering a combination of wear resistance and edge stability suitable for high-force turning applications

• CBN grade WBH30 for hard turning
• Rhombic 35° geometry for controlled cutting
• Negative 0° clearance for stable cuts

Increased productivity through wear-resistant cutting

The use of CBN as the cutting material provides a significant increase in tool life when machining hardened steels, making the insert particularly suitable for applications where frequent tool changes reduce throughput. The WBH30 grade is engineered to maintain a stable cutting edge under high temperatures and abrasive wear, which translates into longer uninterrupted cycles and fewer interruptions for tool replacement. This durability improves machining economy and supports consistent part quality in series production.

Predictable surface finish and process reliability

The Rhombic 35° geometry combined with 0° clearance delivers a reliable shear and a focused cutting action, helping to achieve reproducible surface finishes on hard and pre-hardened steels. The modest corner radius 0.4 mm balances edge strength and finish quality, reducing the risk of microchipping while still allowing controlled material removal. For operators seeking dependable results in hard-turning, the design reduces chatter susceptibility and contributes to a steadier process window.

Application guidance and material compatibility

Designed within the Walter CBN / Hard material series, this insert is intended for hard machining of workpieces classified under hardened-steel applications. It is suitable for turning operations where high hardness and elevated cutting forces demand a wear-resistant, thermally stable cutting edge. When integrating this insert into tooling systems, consider appropriate cutting parameters for CBN tooling and ensure compatible holders to preserve geometric integrity and clamping stability. For specialised workpiece materials or unusual conditions, technical consultation is recommended to optimise parameters.

FAQ

What materials is this insert intended for?
The VNGA160404TM-2 WBH30 insert from Walter Tools is intended primarily for hardened steels and is optimised for hard-turning applications.

How does the CBN grade affect tool life?
The CBN composition of the WBH30 grade provides high wear resistance and thermal stability, resulting in a substantially extended tool life compared with conventional carbide inserts when machining hardened materials.

What is the benefit of the Rhombic 35° shape?
The Rhombic 35° geometry focuses cutting forces and enables controlled material removal, improving surface finish consistency and reducing vibration in demanding turning operations.

Is the insert suitable for finishing as well as roughing?
With a corner radius of 0.4 mm and the controlled geometry, the insert can be used for both finishing and medium-depth turning, depending on the selected cutting data and workpiece hardness.

Can this insert be used on pre-hardened steels?
Yes — the VNGA160404TM-2 WBH30 is suitable for pre-hardened and hardened steel applications; parameter adjustments may be necessary to optimise tool life and surface integrity.
