CCGT09T302-MN2 WNN10 Wendeplatten - Walter Tools

The combination of a coated carbide WNN10 grade, a Rhombus 80° geometry and the MN2 chipbreaker delivers controlled chip formation and stable cutting behaviour for mixed turning and drilling tasks; order the insert directly via Metav Werkzeuge or contact the consultants for application advice.

CCGT09T302-MN2 WNN10 – Drill/turn indexable insert by Walter Tools, Rhombus 80°, MN2 chipbreaker

The CCGT09T302-MN2 WNN10 is a coated cemented carbide indexable insert designed for combined drilling and turning operations where consistent chip control and repeatable edge performance are required

• Coated carbide grade WNN10 for stability
• Rhombic 80° shape for versatile clamping
• 0.2 mm corner radius for precision finishes
• MN2 chipbreaker for controlled chip formation

Reliable geometry for efficient chip control and process stability

The insert’s geometry combines a Rhombus 80° shape with an optimised MN2 chipbreaker, which together support predictable chip flow and reduced risk of edge build-up. The coated cemented carbide WNN10 grade provides a balance between wear resistance and toughness, making the component suitable for a range of workshop tasks where consistent cutting performance is needed. These design choices reduce downtime from unstable chips and contribute to smoother cycle times on multi-operation machines.

Precision edge and surface quality for finishing-sensitive components

A 0.2 mm corner radius and a relief angle of 7° produce a controllable cutting edge that helps achieve uniform surface finishes while maintaining dimensional accuracy. The moderate corner radius supports fine finishing without sacrificing edge strength during interrupted cuts or entry/exit conditions. The insert thickness T3 and tolerance class G ensure mechanical stability in robust toolholders, helping to maintain repeatable part quality across batches.

Practical guidance: selection, clamping and application checks

Selection of the correct grade and geometry should be guided by the specific product matrix and the workpiece material; the series is listed as Walter Schneidstoffsorte - Serie offen, so material suitability must be verified in the product matrix. The insert’s Rhombus 80° form allows flexible clamping in standard turning and drilling toolholders. For operations with high cutting speeds or special materials, verify compatibility with the WNN10 coating and chipbreaker performance to ensure optimal wear behaviour and tool life.

FAQ

What machining tasks is this insert suitable for?
The CCGT09T302-MN2 WNN10 insert by Walter Tools is intended for combined drilling and turning operations where controlled chip formation and repeatable edge performance are priorities.

How does the MN2 chipbreaker affect cutting?
The MN2 chipbreaker on this insert promotes short, manageable chips and supports consistent evacuation, which improves process reliability during both drilling and turning.

Is the WNN10 grade suitable for all materials?
WNN10 is a coated cemented carbide grade; material suitability should be checked against the product matrix for the CCGT09T302-MN2 WNN10 to ensure the correct application envelope.

What clamping considerations apply to the Rhombus 80° shape?
The Rhombus 80° geometry allows flexible clamping options in standard toolholders but requires correct seat and clamp pressure to achieve the specified tolerance class G and stable cutting conditions.
