CNGA120408TM-2 WBH10 indexable turning insert, CBN grade for hard turning — Walter Tools

CNGA120408TM-2 WBH10 is an indexable turning insert engineered for hard machining tasks and optimised for consistent performance in hardened steels and similar high-wear materials

• CBN grade WBH10 for hard machining
• Rhombic 80° geometry for versatile turning
• Corner radius 0.8 mm for predictable edge life
• 0° clearance (negative) for robust cutting action

High-process stability and long tool life for hard turning

The CBN-based WBH10 grade is designed specifically for the demands of hardened steels, delivering exceptional wear resistance and stable chip behaviour in high-contact applications. As a CBN insert, it provides a significantly harder cutting edge than conventional carbide, which reduces flank wear and helps maintain dimensional accuracy over longer tool life. This reliability translates into fewer tool changes and more predictable production runs, supporting higher overall equipment effectiveness in hard-turning processes.

Geometry that improves cutting control and surface quality

The Rhombic 80° geometry combined with a 0.8 mm corner radius offers a balance between accessibility and edge strength, allowing for versatile turning strategies without compromising stability. The negative 0° clearance contributes to a more robust cutting edge, making the insert suitable for heavy interrupted cuts and final finishing of hardened components. Together these features yield improved surface uniformity and repeatable tolerances, particularly where controlled chip flow and edge security are essential.

Application advantages and practical notes for production

As part of the Walter CBN / Hartstoff series, this indexable insert is intended for hard and pre-hardened workpieces and aligns with ISO classifications for hardened materials (group H). The design supports consistent process parameters and reduced variance in batch production, which is particularly valuable for aerospace, tooling and die, and other high-precision sectors. For complex specifications or unusual alloys, consult our technical team for recommended cutting data; Metav Werkzeuge can provide tailored recommendations and delivery options to match production requirements.

FAQ

What materials is this insert suitable for?
The CNGA120408TM-2 WBH10 insert is designed primarily for hardened steels and is also suitable for pre-hardened steel applications under the Walter CBN / Hartstoff series.

How does the WBH10 grade differ from carbide inserts?
WBH10 is a CBN cutting material offering superior hardness and wear resistance compared with carbide, which results in longer edge life and improved dimensional stability on hard workpieces.

Which operations benefit most from this insert?
This insert is especially effective in hard turning operations that demand robust edge security and consistent surface finish, including finishing and heavy interrupted cuts on hardened components.

Is the geometry suitable for tight‑access turning?
The Rhombic 80° form provides versatile access combined with a strong edge; the 0.8 mm corner radius helps maintain edge life while allowing precise contouring.
