WNGG080408M-MN3 WNN10 – Trigon 80° turning insert, 0.8 mm corner radius (Walter Tools)

WNGG080408M-MN3 WNN10 is a Trigon-shaped turning indexable insert engineered for reliable general turning applications, combining a negative relief angle and a defined chipbreaker for predictable machining performance.

• Trigon 80° geometry for stable cuts
• Coated carbide WNN10 for broad material range
• MN3 chipbreaker for reliable chip control

Stable geometry that improves process reliability

The Trigon 80° geometry provides a robust cutting edge and an enlarged cutting volume, which leads to improved tool life under interrupted cuts and when handling variable workpiece sections. With a negative 0° relief angle, the insert is configured to withstand higher radial loads and to maintain cutting edge integrity during heavy engagement. For workshop planners and production engineers this means fewer tool changes, reduced machine downtime and a more predictable machining cycle time. The combination of shape and edge preparation promotes consistent chip flow and contributes to repeatable surface results.

Coated carbide grade for versatile material coverage

The WNN10 grade is a coated cemented carbide formulation intended to offer a balance between wear resistance and toughness. This composition allows the insert to be used across a wide range of materials when the specific combination is validated against the product matrix. In practical terms, the coating reduces flank and crater wear during extended runs, while the substrate retains the impact resistance required for tougher turning operations. For those less familiar with grades: a coated carbide insert merges a hard outer layer with a resilient base body to extend service life under varying cutting conditions.

Chip control and edge stability for consistent surface finish

The MN3 chipbreaker is designed to control chip form and evacuation in typical turning tasks, reducing the risk of long, entangling chips and safeguarding the workpiece finish. Efficient chip control also lowers the likelihood of secondary part damage and eases automation integration where predictable chip behaviour is essential. Together with the 0.8 mm corner radius, the insert produces a balance between edge strength and surface quality — the radius contributes to a stronger cutting edge, reducing the chance of premature chipping while still delivering acceptable finishes on turned components.

Practical notes for integration and selection

The insert is supplied as part of the Walter Schneidstoffsorte open series and is identified by the ISO-style designation. Material suitability should be verified against the manufacturer's product matrix before process adoption. When specifying tooling packages, consider the holder geometry compatible with Trigon 80° inserts and ensure clamping systems provide the recommended rigidity. The coded thickness and size values match standard holder families; confirm seat fit and clearance dimensions during tool assembly to maintain tool life and avert unplanned stoppages.
