High-performance CBN for hardened materials

The WBH20 grade is a CBN-based cutting material developed for hard and wear-intensive machining, especially of hardened steels. Its composition and microstructure deliver high abrasion resistance and thermal stability, which reduces flank wear during long turning passes. For process planners and production engineers, this translates into fewer insert changes and steadier part tolerances, supporting predictable cycle times and reduced scrap rates. The combination of CBN technology and a robust substrate offers a measurable improvement in tool life compared with conventional carbide grades when machining steels with elevated hardness.

Geometry designed to stabilise cutting and surface quality

The insert’s 7° relief angle and 0.8 mm corner radius are chosen to balance cutting forces and edge strength for finishing and light roughing in hardened components. The triangular 60° form provides three indexable cutting edges, improving economy per insert without compromising stability. A moderate corner radius aids in achieving improved surface finish while maintaining sufficient edge strength to withstand intermittent cutting conditions. Those specifying tooling for high-precision turning will appreciate the geometry’s role in reducing vibration and ensuring repeatable surface integrity on critical components.

Better productivity through longer edge life and process reliability

Using a CBN insert such as this reduces the frequency of tool changes and machine downtime, which has a direct effect on productivity and unit costs. The material and design of the insert contribute to stable cutting, minimised notch formation and consistent dimensional results across runs. For workshops aiming to optimise throughput on hardened parts, this insert supports tighter production windows without sacrificing part quality. Process documentation benefits from the predictability of CBN performance, simplifying parameter selection and monitoring for operators and engineers alike.

Application fit and handling for industrial workshops

This insert, identified as TCGW110208TM-3 WBH20, is suited to turning operations on hardened steels and pre-hardened components where high wear resistance is required. The insert’s size code and form make it compatible with standard triangular clamping systems used in production turning holders. When integrating into an existing tool set, check seat and clamping dimensions against the insert designation to ensure secure mounting and correct rake/lead presentation. For further specification clarification or machining parameter recommendations, technical consultation with Metav Werkzeuge is available to support process setup and to match the insert to the intended operation.

FAQ

What materials is this insert suitable for?
The TCGW110208TM-3 WBH20 is designed primarily for hardened steels and pre-hardened components, exploiting the WBH20 CBN grade for high wear resistance.

How does the 7° relief angle affect machining?
A 7° relief angle on the insert reduces rubbing and supports a stable cutting action, which helps the WBH20 grade maintain consistent edge life under hard-turning conditions.

Can the triangular shape improve economy?
Yes, the triangular 60° form provides three indexable edges per insert, increasing economy per insert while retaining the stability needed for finishing hardened parts.

Is this insert suitable for finishing operations?
The combination of CBN material and a 0.8 mm corner radius makes the insert appropriate for finishing and light roughing where surface quality and dimensional control are required.
