VNGG160404M-MN3 WNN10 indexable turning insert — Rhombic 35°, MN3 chipbreaker — Walter Tools

A VNGG160404M-MN3 WNN10 indexable turning insert designed for stable, general-purpose turning with a 35° rhombic form and an MN3 chipbreaker to aid predictable chip formation

• Coated carbide grade WNN10
• Rhombic 35° geometry for versatility
• 0° negative rake for stable cutting
• MN3 chipbreaker for controlled chips

Stable performance for routine turning operations

The insert is engineered as a reliable indexable turning insert for industrial turning tasks where consistent outcomes are required. The WNN10 grade denotes a coated carbide composition chosen to balance wear resistance and economy; this coating assists heat and abrasion resistance, extending edge life under common cutting conditions. The Rhombic 35° form provides favourable approach angles for profiling and light to medium turning, while the 0° negative rake supports a secure cutting action that reduces chatter and improves process stability. These characteristics together translate into fewer interruptions and a smoother production flow.

Better chip control and predictable tool life

Effective chip formation is central to productivity; the integrated MN3 chipbreaker is specified to break chips reliably for many standard materials, reducing the need for secondary manual intervention. A corner radius 0.4 helps distribute cutting forces and supports a good surface finish while resisting premature edge failure. The coated substrate and dedicated chip control combine to lower downtime, enabling longer run times between index changes. For operations where reproducible surface quality and tool longevity are priorities, this insert offers a pragmatic balance of cutting stability and maintenance efficiency.

Compatibility, tolerance and application guidance

The insert belongs to the Walter Schneidstoffsorte — open series and is supplied in tolerance class G with execution code G. The Rhombic 35° geometry and nominal size 16 make it suitable for a broad range of toolholders and turning set-ups that accept the VNGG form. Material suitability should be checked against the manufacturer’s product matrix; the grade is described as coated carbide, but the specific workpiece materials and ideal cutting parameters must be confirmed for each application. When matched correctly, the insert supports consistent machining results and straightforward integration into existing turning processes.

FAQ

What materials is this insert suitable for?
Material suitability depends on the Walter Tools product matrix; the VNGG160404M-MN3 WNN10 insert is a coated carbide grade intended for general-purpose turning, but specific workpiece compatibility should be verified against the manufacturer’s recommendations.

How does the MN3 chipbreaker affect machining?
The MN3 chipbreaker on the VNGG160404M-MN3 WNN10 promotes controlled chip formation, reducing entanglement and easing chip evacuation in typical turning operations, which supports steadier productivity.

What benefits does the Rhombic 35° form provide?
The Rhombic 35° geometry offers versatile approach angles for profiling and standard turning; it improves accessibility for certain features while enabling a good balance between cutting force and surface finish.

Is the corner radius suitable for finishing?
The corner radius 0.4 provides a compromise between edge strength and surface quality; it is commonly used where a robust edge and acceptable finish are required without switching to a dedicated finishing geometry.

How is the insert designated for ordering and reference?
Refer to the ISO designation VNGG160404M-MN3 WNN10 or article number VNGG160404M-MN3-WNN10-WALTER when ordering or checking compatibility with toolholders.
