CNGA120408EM-2 WBS10 WBS10 Wendeplatten - Walter Tools

High wear resistance from the WBS10 CBN grade and the rhombic 80° geometry combines for consistent performance; the 0.8 mm corner radius balances edge strength and surface finish. Order the CNGA120408EM-2 WBS10 directly via Metav Werkzeuge or consult our advisors for application guidance.

CNGA120408EM-2 WBS10 indexable turning insert (Walter Tools) — CBN grade, Rhombic 80°

CNGA120408EM-2 WBS10 is an indexable turning insert designed for wear-intensive turning tasks, offering CBN performance for hardened materials and a rhombic 80° geometry for versatile lathe applications.

• CBN grade WBS10 for hardened steels
• Rhombic 80° geometry for stable cutting
• Corner radius 0.8 mm for finish and edge strength
• Negative 0° relief for secure clamping

Higher productivity through targeted wear resistance

The use of CBN as a cutting material in this insert provides significantly improved wear behaviour in demanding turning operations. The WBS10 grade is engineered for hard and heavily abrasive workpieces, which reduces the frequency of tool changes and supports longer uninterrupted machining cycles. This leads to measurable increases in throughput and predictable cycle times. The indexable insert design allows fast repositioning and economical use of the cutting edge, contributing to lower overall machining costs while maintaining process stability.

Reliable cutting performance and secure clamping

The rhombic 80° geometry delivers an advantageous approach angle that balances cutting forces and edge engagement, improving chip control in intermittent and continuous cuts. With a corner radius of 0.8 mm, the insert offers improved edge strength without sacrificing surface quality. The negative 0° relief geometry enhances clamping security in robust toolholders, which in turn increases dimensional consistency and repeatability during series production. These characteristics support process qualifications where reproducible results are required.

Practical application advice and integration into production

Integration of this CBN insert into existing workflows should be guided by material-specific parameters: the CBN cutting material excels on hardened steels and certain superalloys, but the exact results depend on workpiece alloy, hardness and cutting conditions. It is recommended to verify the item against the manufacturer’s product matrix and to adjust feeds and speeds for heat-sensitive materials. The combination of process security and extended tool life makes this insert particularly suited to shops aiming to optimise throughput while preserving workpiece quality.

FAQ

Which materials is this insert most suitable for?
The insert is supplied in a WBS10 CBN grade and is intended primarily for hardened steels and other wear-intensive alloys; check the product matrix for exact workpiece compatibility.

What effect does the 0.8 mm corner radius have on machining?
A 0.8 mm corner radius provides a balance between edge strength and surface finish, improving durability while helping to achieve consistent workpiece quality.

How does the negative 0° relief influence clamping and stability?
The 0° relief negative geometry increases contact stability in the toolholder and reduces the risk of insert movement under heavy cutting loads, supporting repeatable dimensions.

Is a coating specified for this insert?
No coating is specified in the provided data; the cutting performance stems from the CBN material of the WBS10 grade.

What should be checked before selecting this insert for a job?
Confirm the workpiece material and hardness against the manufacturer matrix and validate cutting parameters for the chosen toolholder and machine to ensure optimal results.
