WCGT040204-FN2 WNN10 – Trigon 80° indexable insert with FN2 chipbreaker by Walter Tools

The WCGT040204-FN2 WNN10 is an indexable insert designed for drilling, boring and turning applications, combining a Trigon 80° form with a FN2 chipbreaker to support consistent chip control in a range of machining tasks

• Trigon 80° insert geometry
• Coated carbide grade WNN10
• FN2 chipbreaker for stable chips
• 0.4 mm corner radius, 7° clearance

High machining performance through geometry and grade

The Trigon 80° geometry together with the WNN10 coated carbide provides a balanced compromise between strength and cutting-edge sharpness. This combination reduces cutting forces in interrupted cuts and supports stable engagement in axial operations, which in turn improves tool life and process reliability. The FN2 chipbreaker is engineered for repeatable chip formation, promoting uninterrupted production sequences and minimising the need for secondary chip handling. Where material suitability is crucial, the sort specification recommends consulting the manufacturer’s product matrix before application to ensure optimal results.

Design details that explain the practical benefits

A modest 0.4 mm corner radius ensures robust edge support while preserving acceptable surface finish in many turning and boring tasks; the 7° clearance angle reduces rubbing on the flank and helps maintain cutting stability. The insert’s Trigon form offers three cutting edges per indexation, enabling economical use of each insert and simplified tool setting. The coated carbide composition, identified by the WNN10 designation, gives wear resistance and heat tolerance typical of coated grades; however, specific workpiece compatibility should be verified against the provided grade chart to match process parameters and expected component tolerances.

Application efficiency and process reliability in production

In production environments where repeatability and predictable tool life are priorities, the combination of geometry, chip control and a proven carbide grade supports consistent output and reduced downtime. The insert is released in the Walter Schneidstoffsorte series and is produced to tolerance class G, which contributes to stable seating and repeatable positioning in toolholders. For users seeking predictable economics, predictable wear behaviour and straightforward indexation, this insert is suitable as part of a wider machining strategy—bearing in mind that the exact workpiece materials for which it is optimised should be checked in the product matrix supplied by the manufacturer.

FAQ

What types of machining is this insert intended for?
The insert is intended for drilling, boring and turning operations; the WCGT040204-FN2 WNN10 from Walter Tools is designed to provide stable chip control in axial and radial engagements.

Which grade is used and what does it mean for wear resistance?
The grade is WNN10, a coated carbide class that delivers enhanced wear resistance and thermal stability compared with uncoated grades; users should consult the manufacturer’s matrix for the best match to specific workpiece materials.

How does the FN2 chipbreaker affect machining?
The FN2 chipbreaker promotes consistent chip formation and evacuation, reducing the likelihood of entanglement and supporting continuous operation with fewer interruptions.

Is the insert suitable for all materials?
Material suitability is not universal; the Walter Schneidstoffsorte series recommends checking the product matrix for the WNN10 grade to confirm compatibility with the intended materials and cutting conditions.

How many cutting edges are available per insert?
The Trigon 80° form provides three indexable cutting edges per insert, enabling economical use through multiple reindexes.
