GX24-3F400N20TM-1 WBH20 indexable turning insert — CBN grade for hardened steels (Walter Tools)

The GX24-3F400N20TM-1 WBH20 is a CBN indexable turning insert engineered for hard turning of hardened steels and comparable high-hardness materials.

• CBN grade WBH20 for hard turning
• Optimised chip control 3F400N20TM-1
• High edge stability and wear resistance

Sustained productivity through wear-resistant CBN technology

The CBN-based WBH20 grade delivers exceptional wear resistance, which reduces the frequency of insert changes and supports longer uninterrupted cycles. Because CBN remains dimensionally stable at high temperature and abrasive contact, the insert maintains a predictable cutting edge, enabling consistently high productivity in hard-turning operations. This benefit reduces machine downtime and contributes to a steadier output rate on production lines handling hardened components.

Consistent surface quality and process stability

A stable cutting edge leads directly to reproducible surface finishes and tighter tolerances. The insert’s geometry and the 3F400N20TM-1 chipbreaker are optimised for secure chip formation, decreasing the risk of built-up edge or erratic tool marks. As a result, the machining process becomes more robust: feed and speed windows can be relied upon, and downstream processes benefit from fewer rework operations. The overall effect is improved process stability and predictable part quality.

Specifically developed for hard machining requirements

This insert is intended for machining tasks where material hardness and cutting forces are elevated. The designation H indicates suitability for hardened steels, while the Walter CBN / Hartstoff series reflects a focus on hard-material applications. The insert’s composition and design support effective material removal from materials that challenge traditional carbide grades, making it a practical choice for components subjected to heat treatment or produced from wear-resistant alloys.

Practical guidance for machining and tool selection

When implementing the insert in a production setting, attention to secure clamping and correct seat geometry is advisable to exploit the full potential of the CBN grade. Careful selection of cutting parameters—moderate depths of cut combined with appropriate speeds and feeds for the material class—maximises tool life and surface integrity. Where process windows are narrow, the insert’s reliable performance simplifies parameter optimisation and shortens the commissioning phase for new workpieces.

Tool life economy and handling recommendations

Longer tool life achieved through CBN performance directly reduces tooling costs per part and lowers total cost of ownership in high-volume or continuous machining environments. Handling is straightforward: indexable inserts allow quick seat changes and predictable re-sharpening cycles are avoided. For applications demanding highest reproducibility and minimal variation, the combination of edge stability and optimised chip control contributes to measurable savings over the service life of the tool.

FAQ

What materials is this insert intended for?
The insert is designed primarily for hardened steels (designation H); its CBN WBH20 grade also suits applications where high wear resistance is required.

How does the WBH20 grade improve process stability?
WBH20 provides high edge stability and thermal resistance; the stable cutting edge reduces dimensional drift and supports reproducible surface quality when hard turning.

Is the GX24-3F400N20TM-1 suitable for continuous production?
Yes, the GX24-3F400N20TM-1 WBH20 insert is aimed at production environments where long tool life and predictable change intervals matter.

Which chipbreaker should be selected for heavy interrupted cuts?
The integrated 3F400N20TM-1 chipbreaker is optimised for controlled chip formation; for very heavy interruptions, review clamping and parameter windows to ensure cutting stability.

Are these inserts original Walter Tools products?
The described insert is an original Walter Tools item from the Walter CBN / Hartstoff series, intended for reliable performance in hard machining.
