CCGT120404-MN2 WNN10 — Indexable turning and boring insert, Rhombic 80° with MN2 chipbreaker (Walter Tools)

The CCGT120404-MN2 WNN10 is an indexable insert for turning and boring operations, designed to deliver stable chip formation and productive machining with a coated carbide grade.

• Rhombic 80° cutting geometry
• MN2 chipbreaker for consistent chips
• 7° relief angle for secure cutting
• Coated carbide grade WNN10 for durability

Predictable chip control from geometry and chipbreaker

The rhombic 80° geometry combined with the MN2 chipbreaker offers dependable chip formation and evacuation, which reduces interruptions and increases machining time between interventions. The geometry concentrates cutting forces where the insert is strongest, while the chipbreaker shapes and breaks chips to prevent long, tangled swarf. This results in a measurable increase in process stability and more consistent cycle times when compared with plain-edge inserts. The design is particularly advantageous in repetitive production environments where repeatability and minimal downtime are priorities.

Coated carbide grade for consistent edge life

The insert uses the Walter grade WNN10, a coated carbide class that provides balanced wear resistance and toughness. The coating enhances the cutting edge’s resistance to abrasion and adhesion, extending usable life under a range of operating conditions. As the grade is part of Walter’s open series, compatibility with specific workpiece materials should be verified against the product matrix; this ensures the chosen grade aligns with the intended substrate and machining strategy. The practical outcome is fewer tool changes and a more predictable tool-cost profile across production runs.

Dimensional features that aid setup and surface quality

Key dimensional data such as the 0.4 mm corner radius, 7° relief angle and the rhombic plate form support reliable seating in toolholders and predictable surface finishes. The plate size (12) and thickness (04) are designed for standard toolholder families, and the tolerance class G indicates consistent manufacturing precision for repeatable positioning. A modest corner radius helps to achieve a fine surface on finishing passes while still offering sufficient edge strength for light roughing. Together, these details reduce setup iterations and help maintain consistent part quality across batches.
