CCGT120408-FN2 WNN10 – Turning insert with FN2 chipbreaker (Walter Tools)

A versatile coated-carbide turning and boring insert, CCGT120408-FN2 WNN10, with a rhombic 80° form for adaptable toolpaths and stable cutting performance.

• Coated carbide WNN10 for stable cutting
• FN2 chipbreaker for reliable chip control
• Rhombic 80° form for versatile turning
• 0.8 mm corner radius for fine finishing

Increased process reliability through grade and chip control

The combination of the WNN10 coated-carbide specification and the FN2 chipbreaker is engineered to deliver consistent cutting behaviour across a broad range of turning operations. Coated carbide provides a balance between wear resistance and toughness; this reduces flank wear and helps maintain dimensional accuracy over longer tool life. The designated chipbreaker actively manages chip formation, which lowers the risk of built-up edge and interrupted cutting, contributing to stable cycle times and fewer secondary operations.

Flexible geometry for accurate finishes and diverse toolpaths

A rhombic 80° insert form with a 0.8 mm corner radius and a 7° relief angle offers a compromise between approach angles and strength, enabling both axial and radial cuts with predictable small-step finishing passes. The plate size (12) and thickness (04) support secure clamping in standard toolholders while the modest corner radius aids in achieving fine surface quality without sacrificing edge robustness. These geometric choices make the insert suitable for applications that require controlled material removal and repeatable surface results.

Practical selection and integration into production

This insert belongs to the Walter tools open series and is specified as a coated carbide type; catalogue-dependent material options may be available. The ISO designation and SKU allow compatibility checks against toolholder inventories and process matrices: use the ISO ID when configuring tool assemblies. If material-specific suitability requires confirmation, the product matrix should be consulted to verify the WNN10 grade for the intended workpiece material. For procurement and quick replacement, Metav Werkzeuge can assist with selection, ensuring the insert fits existing holders and cutting strategies.

FAQ

What materials is this insert suitable for?
The suitability of the insert depends on the specific application matrix; the CCGT120408-FN2 WNN10 is a coated-carbide grade intended for a broad range of turning operations, but material compatibility should be checked in the product matrix.

How does the FN2 chipbreaker affect machining?
The FN2 chipbreaker on this Walter Tools insert promotes consistent chip shape and evacuation, reducing the likelihood of built-up edge and supporting stable cutting conditions during general turning and boring.

Which toolholders are compatible with the rhombic 80° form?
Standard toolholders designed for rhombic 80° inserts will accept the CCGT120408-FN2 WNN10; verify seat type and clamping dimensions against the ISO designation to ensure secure mounting.

What finish can be expected with a 0.8 mm corner radius?
A 0.8 mm corner radius typically produces finer surface finishes than larger radii while maintaining edge strength, making it suitable for finishing passes where dimensional accuracy and surface quality are required.

Is this insert part of a larger series with alternative grades?
Yes, this item is listed in the Walter open series; alternative grades and catalogue-dependent options are available—consult Metav Werkzeuge or the product matrix for grade selection.
