WNGG080404M-MN3 WNN10 Turning insert — Trigon 80°, MN3 chipbreaker — Walter Tools

WNGG080404M-MN3 WNN10 is a coated carbide turning insert with trigon 80° geometry and an MN3 chipbreaker, designed for stable chip formation and reliable turning across a range of applications.

• Trigon 80° geometry for robust turning
• Coated carbide grade WNN10 for stability
• MN3 chipbreaker for controlled chip formation
• Negative 0° rake for secure cutting

Stable chip control for continual production

The combination of the MN3 chipbreaker and the trigon profile provides consistent chip control, reducing interruptions and improving cycle stability. The chipbreaker is engineered to break long chips into manageable segments, which lowers the risk of entanglement and supports safer material removal. The result is a more reliable machining process with fewer stoppages and easier chip handling during extended production runs.

Geometry that stabilises cutting forces and improves edge life

The Trigon 80° geometry and negative 0° rake contribute to a secure cutting engagement that resists vibration and reduces shock at the cutting edge. This geometry directs cutting forces into the toolholder, which, combined with tolerance class G, helps maintain dimensional accuracy and repeatability. For operations where rigidity and stability are paramount, the triangular form offers improved support compared with sharper-angle inserts, translating into steadier surface finishes and predictable wear behaviour.

Coated carbide grade and material guidance for reliable selection

The insert is produced in a coated carbide grade identified by the manufacturer series and should be selected against the documented product matrix. The series designation indicates a coated hardmetal construction, which typically supports a wide range of steels and engineering materials; however, exact material suitability must be verified in the product matrix before application. Checking the product matrix helps to align cutting parameters with the insert's coating, grade and expected operating conditions for optimal performance.

Predictable performance through measured dimensions and form

With a corner radius 0.4 and insert size 08, the geometry balances cutting strength and surface finish capability. The thickness and form yield a robust seat in the toolholder and contribute to steady heat distribution at the cutting edge. The full designation, WNGG080404M-MN3 WNN10, combines these attributes into a compact solution that supports consistent cycle times and simplifies process planning when the selected geometry and grade match the intended application.

FAQ

What materials is the WNGG080404M-MN3 WNN10 suited to machine?
The WNGG080404M-MN3 WNN10 is a coated carbide turning insert; material suitability varies with the specific product matrix, so the machining of particular steels or alloys should be confirmed against the manufacturer's recommendations.

How does the MN3 chipbreaker affect machining?
The MN3 chipbreaker on this turning insert is designed to produce short, controlled chips, improving safety and reducing interruptions during continuous turning operations.

What is the effect of the negative 0° rake on cutting performance?
A negative 0° rake increases cutting edge support and resistance to mechanical shock, which benefits roughing and heavier cuts by improving edge stability and reducing chipping.

How does the corner radius influence surface finish and tool life?
The 0.4 corner radius balances edge strength and finish quality; a larger radius generally increases edge robustness and tool life, while smaller radii can improve surface finish at lighter cuts.

Which tolerances and fit should be expected for toolholders?
The insert is supplied in tolerance class G, which indicates standardised dimensional tolerances for a secure fit and predictable clamping in compatible toolholders.
