CCGT120408-MN2 WNN10 / CCGT120408-MN2 WNN10 / WNN10 Bohr-/Aufbohrwendeschneidplatte / Drehwendeschneidplatte — Walter Tools

CCGT120408-MN2 WNN10 is a rhombic 80° indexable insert designed for drilling, boring and turning operations, optimised for controlled chip formation and repeatable cutting performance.

• Coated carbide grade WNN10 for robustness
• Rhombic 80° geometry for versatile cutting
• 0.8 mm corner radius for fine finishing
• 7° clearance angle for secure chip evacuation

High productivity through targeted chip control

The combination of the MN2 chipbreaker and the WNN10 coated carbide grade delivers reliable chip formation across a range of machining tasks. The chip control geometry is designed so that chips are guided away from the cutting edge, reducing the risk of re-cutting and improving cycle stability. This behaviour is particularly advantageous in mixed operations where turning and boring are performed consecutively, as the insert performance has been optimised to maintain consistent cutting forces and predictable tool life.

Precise geometry for surface quality and repeatability

The rhombic 80° shape with a 0.8 mm corner radius and a 7° clearance angle supports fine finishing while retaining robustness for medium-depth cuts. A small corner radius improves surface finish and reduces vibration when smaller allowances are machined, whereas the clearance angle helps prevent rubbing and minimises heat build-up at the flank. The compact plate profile and the specified tolerance class ensure repeatable seat and indexing behaviour, which benefits setups where rapid tool changes and minimal rework are required.

Flexible specification and catalogue-based material options

The insert is supplied in the Walter Schneidstoffsorte - Serie offen and the exact substrate/coating combination is catalog-dependent, allowing selection to match specific application demands. The plate thickness 04 and insert size 12 are standardised dimensions that facilitate integration with common toolholders for drilling, boring and turning operations. Where material compatibility must be verified, the substrate and coating details should be checked in the technical matrix to confirm suitability for the intended workpiece materials and cutting conditions.
