VNGA160408TS-2 WBK20 — Turning indexable insert by Walter Tools (CBN grade, Rhombic 35°)

The VNGA160408TS-2 WBK20 is a CBN-grade turning indexable insert designed for hard, wear-intensive turning tasks where tool life and process stability are essential.

• CBN grade WBK20 for hard, wear‑resistant cutting
• Rhombic 35° insert geometry for versatile turning
• 0° (negative) relief angle for stable cutting forces
• 0.8 mm corner radius for consistent surface finish

Efficient machining of hardened materials with minimal tool changes

The use of CBN in the WBK20 grade targets applications with high abrasive wear and hardened steels; this results in markedly extended tool life compared with conventional grades when used under suitable conditions. As a consequence, cycle times and the frequency of tool changes are reduced, improving overall shop-floor productivity. The insert’s composition and classification should be checked against the supplier’s product matrix to confirm compatibility with specific alloys such as cast materials or superalloys, ensuring the correct balance between performance and cost efficiency.

Stable cutting geometry for reproducible results and surface quality

The rhombic 35° shape combined with a 0° (negative) relief angle provides a geometry that controls cutting forces and promotes stable chip flow. The 0.8 mm corner radius supports consistent part finish and helps absorb minor machine or clamping variations, reducing the risk of chatter on interrupted cuts. The integrated chipbreaker 2 contributes to predictable chip formation in medium to heavy cutting conditions, while the specified tolerance class G ensures interchangeability and reliable seat fit in standard toolholders. These features jointly support repeatable results across production batches.

Application guidance, suitability and process security

This insert is supplied as part of the open Walter cutting‑grade series and suits operations that prioritise durability and process security; it is especially relevant for finishing or semi‑finishing of hardened components where CBN is the preferred hard material solution. For best results, cutting parameters should be adapted to machine rigidity, workpiece material and coolant strategy; the series documentation recommends verifying material suitability on the manufacturer’s product matrix. The combination of robust grade and precise geometry yields lower downtime and predictable performance—key advantages for production environments seeking cost‑effective, high‑quality machining.

FAQ

What materials is this insert suitable for?
The VNGA160408TS-2 WBK20 features a CBN grade intended primarily for hardened steels and other highly abrasive materials; specific suitability should be verified against the Walter product matrix.

How does the 0° (negative) relief angle affect performance?
A 0° (negative) relief angle increases edge strength and cutting stability under heavy or interrupted cuts, making the insert well suited to demanding turning operations with higher radial forces.

Can this insert be used for finishing operations?
Yes, the 0.8 mm corner radius and controlled chipforming make the insert suitable for finishing and semi‑finishing where consistent surface quality is required.

What should be checked before using the insert on a new material?
Check the manufacturer’s material matrix for the WBK20 grade and confirm machine rigidity, clamping and coolant strategy to ensure optimal tool life and process security.

Is the geometry compatible with standard VNGA toolholders?
The ISO designation VNGA160408TS-2 corresponds to standard insert seating; tolerance class G ensures interchangeability in compatible holders.
