RCGT120400-MN2 WNN10 turning indexable insert, 7° relief — Walter Tools

The RCGT120400-MN2 WNN10 is a round turning insert engineered for precision external turning and consistent chip control in production environments.

• Coated carbide grade WNN10
• 7° relief angle for stable cutting
• Round insert RCGT120400-MN2
• MN2 chipbreaker for controlled chips

Reliable chip control for predictable cycle times

The insert is designed around a purposeful MN2 chipbreaker combined with a coated carbide grade, which together promote stable chip formation and reduce unexpected interruptions. This configuration supports repeatable machining by managing chip flow and minimising rework. The modest 7° relief angle lowers cutting forces during engagement, which helps to protect the tool edge and maintain consistent dimensional results when used within its application matrix.

Consistent part quality with simple geometry

A round insert with a zero nose radius and a compact size simplifies set-up and contributes to uniform surface finish on turned external profiles. The geometry suits operations where small radii and contouring are frequent, while the insert’s construction supports steady cutting performance across batch runs. Operators should consult the supplied product matrix to confirm material suitability and cutting parameters before first use to achieve the best balance between tool life and workpiece quality.

Process reliability and integration into existing toolholders

The insert follows ISO designation standards and integrates easily into standard turning toolholders, enabling quick changeover and predictable tool behaviour in production cells. The use of a recognised Walter Tools grade from an open series offers wide availability and consistent manufacturing tolerances, supporting efficient stock rotation in toolrooms. For applications requiring traceable performance, the coated carbide composition and chipbreaker design provide measurable improvements in machining stability.

FAQ

What materials is this insert suitable for?
The insert is specified with the WNN10 coated carbide grade; please check the product’s material compatibility matrix to confirm suitability for specific materials.

Which chip control behaviour can be expected from this geometry?
The MN2 chipbreaker is intended to produce controlled, short-to-medium chips that enhance process stability in external turning.

How does the 7° relief angle affect cutting performance?
A 7° relief angle reduces radial cutting forces and helps maintain edge stability, especially during continuous turning operations.

Can this insert be used in standard toolholders?
Yes, the ISO designation and round form permit integration into standard turning toolholders that accept the RCGT family.
