CNGG120404M-MN3 WN10 Drehwendeschneidplatte — rhombic 80°, 0° negative rake — Walter Tools

The CNGG120404M-MN3 WN10 is a rhombic 80° indexable insert for external turning, featuring a 0° negative relief angle and an MN3 chipbreaker for controlled swarf formation.

• Rhombic 80° geometry for secure clamping
• Uncoated carbide grade WN10 for broad use
• MN3 chipbreaker for predictable chip control
• Corner radius 0.4 mm for stable edge life

Reliable chip control for steady production

The MN3 chipbreaker is engineered to provide predictable swarf formation under a range of cutting conditions. By combining this chipbreaker with the uncoated WN10 carbide, the insert supports consistent chip breakage and easier swarf evacuation, which reduces process interruptions. This configuration suits serial turning where repeatability and machine uptime are priorities, helping to keep cycle times stable and secondary operations minimal.

Geometry that improves seating and edge stability

The rhombic 80° shape with a 0° negative relief angle offers a compact seating area and secure clamping, decreasing the likelihood of insert displacement under interrupted cuts. The corner radius 0.4 mm balances strength and surface finish: small enough to permit accurate profiling, yet large enough to distribute cutting forces and extend cutting-edge life. These geometry choices combine to enhance dimensional stability across batches.

Practical selection and verification for materials

The insert is supplied in the WN10 grade, an uncoated carbide formulation; customers should verify material suitability against the specific product matrix before application. The grade is intended as a versatile option, but material compatibility should be checked for specialised alloys or heat-treated components to ensure optimal tool life. For non-standard workpiece materials, consult the machining data matrix or request specific recommendations from Metav Werkzeuge.

Integration into the workshop and process benefits

With tolerance class G and standard size code 12, the insert is straightforward to stock and replace, promoting fast tool changes and reduced setup time. The form factor and chipbreaker support stable swarf behaviour, which can lower housekeeping time and reduce the risk of machine downtime. Combined with Walter Tools’ manufacturing consistency, this insert contributes to predictable production results and simplified process planning.

FAQ

What is the chipbreaker type and what does it do?
The insert uses the MN3 chipbreaker, which promotes controlled chip formation and easier evacuation during turning operations.

Is this insert coated or uncoated?
The grade WN10 specified for this insert is an uncoated carbide formulation; the insert is intended as an economical, versatile cutting option.

Which geometry ensures stable seating for interrupted cuts?
The rhombic 80° shape combined with a 0° negative relief angle provides a compact seating and secure clamping suitable for interrupted and general turning tasks.

How does the corner radius influence performance?
The 0.4 mm corner radius balances edge strength and surface finish, improving edge life while allowing accurate contouring in production work.

Should material suitability be checked before use?
Yes, the WN10 grade is versatile, but material compatibility should be verified against the product matrix to ensure optimal tool life and machining results.
