CCGW060208TM-2 WBH20 — CBN turning insert for hard machining (Walter Tools)

A CCGW060208TM-2 WBH20 rhombic insert engineered for hard machining and precision turning of hardened steels and similar difficult-to-cut materials.

• CBN grade WBH20 for hard machining
• Rhombus 80° form, 0.8 mm corner radius
• 7° clearance angle for stable cutting
• Chipbreaker type 2 for controlled chips

Maximised tool life for hard, high-wear applications

The insert is made in a CBN cutting grade, offering markedly higher wear resistance for machining hardened and heat-treated components than conventional carbide grades. CBN (cubic boron nitride) is a superabrasive that maintains cutting-edge integrity at elevated contact stresses, which directly reduces flank and crater wear. The result is fewer tool changes, longer uninterrupted runs and more predictable shift planning for production environments where component hardness is a limiting factor.

Geometry that improves process stability and surface quality

The combination of a Rhombus 80° form with a 0.8 mm corner radius and a 7° clearance angle supports controlled engagement and consistent tool life. The modest corner radius balances strength and finishing capability, while the clearance angle prevents rubbing on the flank face during interrupted cuts. The integrated chipbreaker type 2 promotes manageable chip formation, reducing the risk of built-up edge and improving repeatable surface finishes on hard materials. These geometric decisions translate into stable cutting forces and fewer rejected parts.

Designed for seamless integration into hard-turning routines

As a turning insert produced by Walter Tools, the part is intended for use in applications such as hard turning of hardened steels and pre‑hardened components. The product’s specifications favour industrial settings that prioritise process security and repeatability; the insert supports higher cutting parameters than standard inserts when appropriate, enabling shorter cycle times without sacrificing component integrity. The benefit is a more productive machining cell with consistent results across batches.

Reliable option for demanding materials and repeatable results

The insert’s CBN composition and robust geometry make it suitable for applications where wear rates are high and tool life directly affects output costs. In practice, this means improved mean time between tool changes and reduced variability in surface quality. The technical specification and material suitability are intended to help planners and operators specify the right grade for hard machining tasks, supporting methodical tool selection and stable production planning.

FAQ

What materials is the insert suited for? The insert is specified for machining hardened steels and pre-hardened components; the WBH20 CBN grade is intended for hard machining tasks.

How does the corner radius affect performance? A 0.8 mm corner radius provides a balance between edge strength and surface finish, reducing edge chipping while maintaining acceptable finishing capability for hard turning.

Which chip control can be expected? The integrated chipbreaker type 2 promotes controlled chip formation, helping to avoid long, tangled chips and improving operational safety and surface consistency.

Is this insert appropriate for interrupted cuts? Yes — the geometry, clearance angle and CBN grade give enhanced resistance to the stresses of interrupted cutting in hardened materials.
