WCGT080404-MN2 WNN10 — Boring and Turning Indexable Insert, Trigon 80°, Walter Tools

WCGT080404-MN2 WNN10 is an indexable insert designed for turning and boring tasks, featuring a Trigon 80° shape, a 0.4 mm corner radius and an MN2 chipbreaker for predictable chip control across a range of catalog-dependent grades.

• Trigon 80° geometry for secure positioning
• WNN10 coated carbide for broad material coverage
• MN2 chipbreaker for consistent chip formation
• 7° clearance angle and 0.4 mm corner radius

Stable chip control for reliable productivity

The Trigon 80° geometry combined with the MN2 chipbreaker delivers controlled chip formation, reducing variability in cycle times and easing swarf handling. The combination of geometry and chipformer is tailored for medium to general machining tasks and supports steady productivity in series production. The controlled chip flow reduces stoppages and contributes to lower tool-change frequency, which benefits overall process efficiency and line uptime.

Geometry and grade tailored for flexible machining

The insert’s Trigon 80° profile and 0.4 mm corner radius enable robust edge strength while maintaining the ability to produce consistent surface finishes. The grade is listed as WNN10 (coated carbide) and is catalogue-dependent; this means the substrate and specific coating options vary by catalogue entry to match the workpiece material and cutting conditions. Check the product matrix to confirm the optimal combination of substrate and coating for the intended application.

Precision fit and cutting clearance for repeatable results

A 7° clearance angle supports effective cutting engagement and helps avoid rubbing during depth changes or bore entry. The standardised geometry and tolerance class ensure repeatable seating and indexing in compatible toolholders, simplifying tool management and reducing set-up time between jobs. Together, these attributes help maintain part tolerances and reduce scrap rates in production environments.

Selection and application guidance for process security

Grade choice and coating options influence wear behaviour and should be selected against the workpiece material and machining strategy; consult the product matrix for suitability. As the WNN10 grade is a coated carbide class, it is intended to balance wear resistance and edge toughness for a wide range of materials — final selection depends on the required surface quality and cycle time targets. For critical or mixed-material batches, select the catalogue variant that best aligns with cutting speed and feed parameters.

FAQ

What applications is this insert suited for?
This insert is intended for turning and boring operations where the Trigon 80° geometry and MN2 chipbreaker support controlled chip formation and repeatable results.

Can the WNN10 grade be used on hardened steels?
The WNN10 grade is a coated carbide class; suitability for hardened steels must be checked in the product matrix to confirm the correct catalogue variant and cutting parameters.

How does the 0.4 mm corner radius affect finishing?
A 0.4 mm corner radius provides a balance between edge strength and surface finish, improving edge life while still allowing acceptable surface quality in many turning applications.

Is the insert compatible with standard toolholders?
The Trigon 80° form and tolerance class G support secure seating in compatible indexable insert toolholders; verify holder compatibility by size code and clamping style.

What is the role of the MN2 chipbreaker?
The MN2 chipbreaker is designed for predictable chip control in general machining, improving swarf management and reducing interruptions from poor chip formation.
