VNGA160408TM-2 WBH10C — Turning indexable insert, CBN grade, for hardened steels (Walter Tools)

The VNGA160408TM-2 WBH10C is a CBN-coated rhombic insert designed for hard turning and machining of hardened steels, offering high process stability in demanding finishing and light roughing applications.

• Coated CBN grade for high wear resistance
• Rhombic 35° form for versatile turning
• 0° negative relief for maximum edge strength

Exceptional wear resistance for hard machining

The WBH10C grade belongs to the Walter CBN series and uses a CBN-based coating system engineered for hardened steels and pre-hardened components. This composition provides substantially higher tool life than conventional carbide grades when cutting at the elevated stresses typical of hard turning. The result is a more consistent process window, fewer indexings and reduced unexpected downtime, which together improve overall economic efficiency in serial production.

Geometry that ensures stable cutting and surface quality

The rhombic 35° insert form combined with a 0° negative relief delivers outstanding edge support under high cutting forces. The 0.8 mm corner radius increases edge robustness and helps maintain a reliable surface finish even under interrupted cuts. The integrated chipbreaker 2 promotes controlled chip formation when machining hard materials, reducing the risk of built-up edge and minimising surface damage. These geometric choices make the insert well suited to finishing passes and light roughing where dimensional accuracy and repeatability matter.

Practical integration and recommended use

With a nominal size of 16 mm and a thickness designation of 04, the insert fits standard VNGA-style toolholders and can be indexed for multiple edges to lower tooling costs per part. The insert is marked for ISO group H, confirming suitability for hardened steels and pre-hardened workpieces. Selection assistance and cutting-parameter guidance are available to match speed, feed and depth of cut to the specific hard material being machined, ensuring the best balance between productivity and tool life. Selection tools and process data from Metav Werkzeuge support parameter setting and replacement strategy for stable series production.

FAQ

What materials is this insert intended for?
The VNGA160408TM-2 WBH10C insert is intended primarily for hardened steels (ISO group H) and is specifically engineered for hard turning and pre-hardened components.

How does the 0° negative relief affect performance?
The 0° negative relief increases edge support and durability; the VNGA160408TM-2 WBH10C benefits from this geometry when cutting under high forces, improving tool life and stability.

What is the benefit of the 0.8 mm corner radius?
A 0.8 mm corner radius on the VNGA160408TM-2 WBH10C balances edge strength and surface finish, allowing stable finishing passes and improved resistance to edge chipping.

Can the insert be used for finishing and light roughing?
Yes, the design and WBH10C grade are suited to finishing and light roughing of hardened steels, where consistent surface quality and repeatable dimensions are required.
