CCGT09T308-MN2 WNN10 – Indexable insert for drilling, boring and turning, Rhombic 80° with 0.8 mm corner radius · Walter Tools

The CCGT09T308-MN2 WNN10 is an indexable cutting insert suited to combined drilling/boring and turning tasks where consistent chip control and repeatable edge life are required, especially in mixed production environments.

• Coated carbide grade WNN10
• Rhombic 80° geometry
• MN2 chipbreaker for stable chips
• 0.8 mm corner radius for robustness

High productivity through material and geometry synergy

The insert pairs the WNN10 coated carbide grade with a targeted geometry to deliver reliable cutting performance across a wide range of operations. The combination of a modern coating and the MN2 chipbreaker reduces built-up edge formation and supports continuous cutting cycles, which translates into longer tool life and fewer indexings per component. This results in measurable productivity gains in batch production and reduced process variance, particularly where operators require predictable tool behaviour under varying cutting conditions.

Consistent surface finish and tool life from precise geometry

The rhombic 80° form and a 7° relief angle create stable cutting engagement and favourable load distribution at the cutting edge, while the 0.8 mm corner radius increases resistance to chipping where intermittent cuts occur. The MN2 chipbreaker aids controlled chip segmentation, lowering the risk of tangling and improving coolant access. Together, these design elements support consistent surface quality and less rework, making the insert well suited to components that demand repeatable dimensional and visual standards.

Application guidance and selection tips for production planners

This insert is offered in T3 thickness with tolerance class G and insert size 09, specified under the ISO designation CCGT09T308-MN2 WNN10; these data points assist in fixture and toolholder selection. The cutter grade is a coated carbide class, so suitability for particular workpiece materials should be confirmed using the product matrix. For applications requiring special film or substrate characteristics, consult the technical data sheet to match cutting parameters and cooling strategies to the chosen grade and geometry.

FAQ

What machining operations is this insert designed for? The insert is intended for combined drilling, boring and turning applications; the ISO designation CCGT09T308-MN2 WNN10 identifies it as an indexable insert suited to these tasks under the Walter Tools range.

Which materials can be machined with this grade? The WNN10 coated-carbide grade offers broad applicability, but the precise suitability for a given material should be verified in the product matrix and technical sheet for the CCGT09T308-MN2 WNN10 insert.

How does the MN2 chipbreaker affect cutting performance? The MN2 chipbreaker promotes controlled chip formation and evacuation, reducing clamping risks and improving coolant penetration, which in turn supports consistent surface finish and extended edge life.

How should the insert geometry influence toolholder choice? The rhombic 80° form, 7° relief and 0.8 mm corner radius determine engagement angles and cutting forces; choose a toolholder that secures the ISO seat for CCGT inserts and allows the recommended cutting data to be applied safely.
