CNGA120404EM-2 WBS10 indexable turning insert by Walter Tools — CBN grade, Rhombus 80° geometry

CNGA120404EM-2 WBS10 is an indexable turning insert designed for hardened-material and high-wear machining tasks, offering a robust CBN grade and an 80° rhombic shape for secure seating and consistent cutting performance.

*CBN grade WBS10 for hard materials
*Rhombus 80° geometry for precise engagement
*0° negative rake for stable cutting
*0.4 mm corner radius for consistent surface finish

High-performance CBN for demanding, wear‑intensive turning

The CBN-based WBS10 grade is engineered for hard turning and other high-wear operations, delivering excellent wear resistance and sustained edge life under thermal and abrasive stress. As a cubic boron nitride solution, the material maintains cutting integrity where conventional carbides wear rapidly; this means fewer indexings and predictable tool cycles. The robust substrate and grade selection result in improved process stability, particularly when machining through-hardened steels or components where surface integrity is critical. Practical application requires verification against the specific product matrix to confirm suitability for alloys such as certain cast irons or superalloys.

Geometry that ensures repeatable surface quality and tool life

The Rhombus 80° form combined with a 0° negative rake creates a cutting edge that resists deflection and secures seating in standard toolholders, which promotes dimensional constancy across long production runs. The 0.4 mm corner radius favours a balanced compromise between edge strength and achievable surface finish, reducing the tendency for micro-chipping while supporting stable chip formation. Users with limited metrology experience should note that corner radius and negative rake affect cutting forces and must be considered when selecting feeds and depths of cut to preserve component tolerances.

Practical integration into machining workflows

The insert is supplied in the Walter CBN / Hartstoff series and is intended to be matched with holder systems and cutting data recommended for CBN grades. For best results, consult the cutting data sheet and validate parameters on representative parts; the product matrix should be used to confirm material compatibility and cutting-window optimisation. Where process reliability and repeatable part quality are priorities, this insert offers a rational route to fewer reworks and higher throughput.

FAQ

What materials is this insert suited for?
The CNGA120404EM-2 WBS10 insert is formulated as a CBN grade for hardened and highly abrasive materials; suitability should be checked against the product matrix for specific steels, certain cast irons or superalloys.

How does the 0° negative rake influence cutting behaviour?
A 0° negative rake increases edge strength and improves stability under heavy loads; the CNGA120404EM-2 WBS10 therefore delivers consistent cutting forces and enhanced tool life in demanding turning operations.

Is the 0.4 mm corner radius suitable for finishing passes?
A 0.4 mm radius provides a balance between edge durability and surface quality; for critical finishing passes, adjust feeds and depths to the required surface finish while leveraging the insert’s stable edge.

Which series and manufacturer standard does this insert belong to?
This insert is part of the Walter CBN / Hartstoff series by Walter Tools and should be integrated using the manufacturer’s recommended holders and cutting data.
