CCGT120402-MN2 WNN10 Rhombic 80° indexable insert, MN2 chipbreaker — Walter Tools

A robust CCGT120402-MN2 WNN10 indexable insert for turning and boring, designed to combine controlled chip control with a coated cemented carbide grade for versatile machining tasks.

• Coated carbide grade WNN10 for diverse materials
• MN2 chipbreaker for controlled chip formation
• Rhombic 80° shape with 0.2 mm corner radius
• Positive 7° clearance angle for reliable cutting

Stable chip control for uninterrupted machining

The integrated MN2 chipbreaker is tailored to produce short, controllable chips that reduce the risk of entanglement and machine stops. This controlled chip formation translates into fewer process interruptions and a smoother production flow, which is particularly advantageous on serial turning operations. With predictable chip shapes, tool handling becomes safer and cycle times can be optimised without sacrificing component integrity.

Repeatable edge life and improved surface quality

The WNN10 coated carbide substrate provides a balanced wear resistance and surface finish performance when used within its recommended application matrix. Combined with the rhombic 80° geometry and the 0.2 mm corner radius, the insert sustains a stable cutting edge that helps achieve consistent dimensional accuracy and fine surface texture. The 7° clearance supports a positive cutting action that minimises rubbing and improves heat evacuation at the tool–workpiece interface.

Simple integration and versatile insert handling

As an indexable insert, the CCGT120402-MN2 form allows quick replacement and secure clamping in standard toolholders, reducing set-up time and downtime. The format and thickness code support compatibility with established holder ranges; check the product matrix to confirm suitability for specific machines and materials. For application advice or product-matrix verification, Metav Werkzeuge provides technical consultation by e‑mail or phone to ensure the insert matches the intended machining task.

FAQ

What materials is this insert suitable for?
The CCGT120402-MN2 WNN10 is a coated cemented carbide grade; suitability depends on the specific workpiece material and should be checked against the product matrix for the WNN10 grade and the intended application.

How does the MN2 chipbreaker affect machining?
The MN2 chipbreaker promotes controlled, short chips, improving evacuation and reducing the likelihood of chip-related interruptions in turning operations with the CCGT120402-MN2 WNN10 insert.

What benefit does the rhombic 80° geometry provide?
The rhombic 80° form offers a balanced combination of cutting edge strength and access to shoulders, supporting stable cutting and good surface finish when used with the recommended edge radius and clearance.

How should the corner radius be selected for my part tolerance?
The 0.2 mm corner radius on this insert helps to balance edge strength and dimensional control; choose the radius based on the required surface finish and tolerance, and verify with the process engineers or Metav Werkzeuge if unsure.
