TCGW110204TM-3 WBH20 triangular CBN turning insert by Walter Tools — 7° relief, 0.4 mm corner radius

The TCGW110204TM-3 WBH20 is a triangular, indexable turning insert designed for hard turning applications and demanding finishes on hardened steels and similar hard materials

• CBN grade WBH20 for hard turning
• Triangular 60° insert, 0.4 mm corner radius
• 7° relief angle for stable cutting
• Optimised for hardened steels (H)

Consistent productivity for hard turning applications

The CBN cutting grade WBH20 is engineered for machining hardened steels, providing high wear resistance and stable cutting performance in demanding operations. As an indexable triangular insert, the geometry supports repeatable seating and predictable tool life, which translates into fewer tool changes and better machine uptime. The use of a CBN-based cutting material means that abrasive wear is significantly reduced compared with conventional carbide, so the cutting edge maintains form longer under elevated contact stresses. This reliability improves process stability in series production and in components requiring tight tolerances.

Geometry tuned for edge stability and surface quality

The combination of a triangular 60° shape and a 0.4 mm corner radius gives a balance between edge strength and the ability to achieve good surface finish on hard materials. A measured 7° relief angle helps to lower cutting forces and reduces the tendency for built-up edge when machining high-hardness workpieces. The modest corner radius adds mechanical robustness, supporting light finishing cuts without compromising dimensional control. In practice, these geometric choices mean fewer reworks and a steadier path to the specified surface quality on hardened parts.

Material compatibility and process benefits

This insert is part of the Walter CBN / Hartstoff series and is specifically matched to applications involving hardened steels and pre-hardened components. The cutting grade and chip control features are optimised for high-contact stress environments typical of hard finishing and intermittent cutting. Using a CBN insert for such work reduces thermal softening of the cutting edge and improves wear resistance, which can allow for higher cutting speeds and longer intervals between index changes. As a result, cycle times can be shortened while maintaining repeatable form and finish.

Operational advantages and economic impact

Adopting a CBN insert from a proven series offers tangible process advantages: extended tool life, predictable performance and lower overall tooling costs for hard machining tasks. The robust edge geometry and grade selection support consistent chip formation and easier post-process inspection, reducing scrap and saving operator time. For operations producing hardened components in medium to large batches, the improved tool life and fewer interventions deliver a measurable return on tool investment and smoother production flow.

FAQ

What materials is this insert intended for?
The insert is designed primarily for hardened steels and pre-hardened components; the WBH20 CBN grade is selected for high wear resistance in such applications.

Is the CBN grade suitable for finishing operations?
Yes, the WBH20 grade and the triangular geometry support finishing on hard materials, delivering consistent surface quality and dimensional accuracy.

How does the 0.4 mm corner radius affect performance?
A 0.4 mm corner radius offers a compromise between edge strength and surface finish, improving edge stability during finishing cuts while helping to maintain component tolerances.

Can the insert reduce tooling-related downtime?
Using a CBN insert from the Walter CBN / Hartstoff series typically extends tool life and reduces index changes, which lowers tooling interventions and supports smoother production cycles.

Is chip control optimised for interrupted cuts?
The chipbreaker designation and grade selection are optimised to provide predictable chip behaviour in high-contact stress conditions, improving process stability during demanding cuts.
