CNGG120402M-MN3 WN10 Rhombic 80° indexable turning insert, uncoated carbide — Walter Tools

The CNGG120402M-MN3 WN10 is an indexable turning insert in rhombic 80° form, designed for general turning where consistent edge life and controlled chip behaviour are required

• Uncoated carbide grade WN10
• Rhombic 80° insert form
• 0.2 mm corner radius, 0° negative rake

Consistent cutting performance from an uncoated carbide grade

The open-series WN10 grade is supplied as an uncoated carbide indexable insert that provides dependable wear behaviour in many turning tasks. Thanks to the material choice, edge integrity and repeatability are prioritised over extreme coatings, which makes this insert suitable for shops seeking predictable tool life and simpler dress-and-replace routines. The rhombic 80° geometry yields a stable cutting edge, while the 0.2 mm corner radius reduces the risk of edge chipping on interrupted cuts, improving process stability for common machining operations.

Geometry and chip control designed for reliable productivity

The insert's MN3 chipbreaker is matched to the insert geometry to promote stable chip formation and evacuation in a wide range of cutting conditions. A 0° negative relief angle supports stronger cutting edge support under heavier feeds, reducing the tendency for undesirable vibrations. These combined characteristics result in reduced rework and smoother cycle times, helping to maintain consistent part quality on batch and single-piece production alike.

Practical application and selection guidance for workshop use

Insert size and form make this product suitable for standard turning toolholders that accept CNGG-style inserts; thickness is indicated by code 04 and the nominal plate size is 12, simplifying integration into existing tooling systems. The open-series designation encourages verification of workpiece suitability against the product matrix because the WN10 grade performs best when matched to the correct workpiece material and cutting conditions. For shops seeking an uncomplicated, cost-conscious insert that balances edge life and process reliability, this insert is a pragmatic choice.

FAQ

What materials is this insert intended for?
The CNGG120402M-MN3 WN10 insert is supplied in the open WN10 uncoated carbide grade; suitability for specific workpiece materials should be checked against the manufacturer's product matrix to ensure optimal performance.

How does the MN3 chipbreaker affect machining?
The MN3 chipbreaker promotes controlled chip formation and evacuation, which supports consistent surface finish and decreases the likelihood of chip-related tool or workpiece damage when using the CNGG120402M-MN3 WN10 insert.

What is the benefit of the rhombic 80° form?
The rhombic 80° form provides a robust cutting edge with good access for turning profiles and contributes to stable cutting forces, making it suitable for a range of general turning operations.

Is this insert suitable for interrupted cuts?
The 0.2 mm corner radius and the negative 0° relief enhance edge support and resistance to chipping, improving reliability in interrupted and semi-continuous cutting situations when used within appropriate cutting parameters.
