VNGA160404TS-2 WBK20 indexable turning insert — CBN grade, Rhombus 35°

VNGA160404TS-2 WBK20 is an indexable turning insert designed for hard and highly abrasive turning tasks, offering wear resistance and stable cutting performance in demanding production environments.

• CBN grade WBK20 for hard materials
• Rhombus 35° geometry for versatile engagement
• 0° negative rake for increased edge strength
• Corner radius 0.4 for controlled surface finish

Improved wear resistance for long production runs

The use of CBN (WBK20) provides outstanding hardness and thermal stability, which translates into significantly improved wear resistance during the machining of hardened steels and other high‑abrasion materials. As a result, insert changes become less frequent and cycle times remain consistent, supporting predictable production flow. The hard cutting grade is especially effective where conventional carbide would suffer rapid flank wear; material compatibility should be verified in the supplied product matrix to ensure optimal application.

Stable cutting performance through geometry and edge design

The Rhombus 35° shape combined with a 0° negative rake increases edge robustness and reduces the risk of chipping under interrupted cuts or tough material sections. This geometry supports steady chip formation, while the corner radius 0.4 improves surface integrity without compromising tool strength. The included chipbreaker 2 is configured to assist chip control for a broad range of turning operations, helping to maintain machine uptime and reduce scrap rates through consistent swarf behaviour.

Practical handling and process benefits for workshops

The insert’s designation and form factor follow established industry codes for straightforward identification and toolholder matching, simplifying inventory management and tool change procedures. The thickness code 04 and form code VNGA160404TS-2 facilitate correct seating in compatible toolholders, while the tolerance class G ensures repeatable positioning. For process optimisation, select the insert when machining tasks require high wear resistance and stable tool life; consult the technical matrix for specific workpiece-material pairings and cutting data recommendations.
