DNGA150408EM-2 WBS10 — Indexable turning insert, CBN grade for hardened steels, Walter Tools

DNGA150408EM-2 WBS10 is an indexable turning insert designed for demanding hard-turning tasks and high-abrasion applications in hardened steels and similar high-wear materials

• CBN grade WBS10 for hardened materials
• Rhombus 55° insert geometry
• 0° negative rake angle
• Corner radius 0.8 mm

Maximum wear resistance for extended productivity

The WBS10 cutting grade is a CBN solution developed for machining hardened steels and applications with high abrasive wear. Using cubic boron nitride as the cutting material provides significantly improved edge retention compared with conventional carbides, which reduces insert change frequency and increases uptime. This grade is particularly suitable where dimensional stability and repeatable performance are required; however, the material suitability should be verified against the product matrix to ensure optimal results for cast components or superalloys.

Controlled geometry for predictable chip formation and surface finish

A Rhombus 55° profile combined with a corner radius of 0.8 mm creates a balance between edge strength and surface quality. The rhombic shape supports entering and facing operations with reliable contact angles, while the integrated chipbreaker 2 promotes consistent chip control under varying cutting conditions. The 0° negative rake increases the mechanical robustness of the cutting edge, helping to avoid premature edge damage during interrupted cuts or when machining tough microstructures, and contributes to reproducible surface results with stable cutting forces.

Reliable process integration and application guidance

Delivered in the Walter CBN / Hartstoff series with tolerance class G, this insert is built for process security in production environments where repeatability and tool life are critical. The insert’s thickness and dimensions support stable clamping in standard toolholders designed for rhombic inserts. As the material specification is catalogue-dependent and application behaviour varies with component material, it is recommended to review the product matrix and cutting data for feed and speed windows; adaptation of cutting parameters will maximise both tool life and component quality.

FAQ

Which materials is the WBS10 grade best suited for? The WBS10 CBN grade is optimised for hardened steels and high-wear alloys; the DNGA150408EM-2 WBS10 performs best on materials where enhanced edge retention is required, though the product matrix should be consulted for specific cast or superalloy applications.

What advantage does a 0° negative rake offer? A 0° negative rake increases cutting-edge strength and resistance to chipping, making the insert robust for interrupted cuts and variable feed conditions while maintaining stability in heavy-duty turning operations.

How does the Rhombus 55° geometry influence machining? The Rhombus 55° profile offers versatile entry angles for turning and facing, enabling consistent contact conditions that support reproducible surface quality and steady cutting forces across a range of operations.

Does chipbreaker 2 suit finishing or semi-finishing operations? The integrated chipbreaker 2 is designed to control chip form reliably; depending on cutting parameters it supports both semi-finishing and finishing tasks by promoting short, manageable chips and helping to protect the cutting edge.
