VNMG160404-MP3 WPP20G Turning Insert – for Steel (Walter Tools)

The VNMG160404-MP3 WPP20G is a rhombic 35° indexable turning insert with an MP3 chipbreaker and Tiger‑tec Gold coating, engineered for reliable machining of steel (ISO group P).

• Tiger‑tec Gold coating for wear resistance
• Optimised for machining steel (ISO group P)
• MP3 chipbreaker for reliable chip control
• Rhombic 35° shape with 0.4 mm corner radius

Consistent wear resistance for productive turning

The combination of the WPP20G cutting grade and Tiger‑tec Gold coating yields a wear‑resistant, coated carbide structure that supports long tool life under typical steel turning conditions. The coated substrate was developed to handle the heat and chip formation characteristic of ISO P materials, which results in fewer tool changes and reduced downtime. When fitted in a suitable holder, the insert enables higher cutting parameters while maintaining dimensional consistency; the outcome is increased throughput and lower unit costs per component. The statement of suitability for steel is derived from the material designation P and the grade composition.

Reliable chip control and secure edge stability

The MP3 chipbreaker, paired with the rhombic 35° geometry and a 0.4 mm corner radius, delivers predictable chip shaping and controlled evacuation during turning operations. A 0° negative rake influences cutting forces and edge engagement, making the insert a good option for medium to finishing cuts where surface quality and repeatability are priorities. The rhombic form ensures stable seat contact in standard toolholders and supports straightforward indexing; the controlled edge radius helps preserve surface finish while providing a balance between edge strength and sharpness.

Process security and versatility in production

Tolerance class M and the measured plate dimensions establish this component as a consistent, production‑ready solution for shops machining a broad range of steels. The insert’s design promotes process security through reproducible tool performance and stable chip formation, which is particularly relevant in serial production and mixed‑batch environments. Compatibility with common clamping systems and straightforward insert handling reduce setup complexity, while the grade’s universal characteristics allow its use across a variety of steel types without frequent grade swaps. The result is dependable repeatability and efficient integration into existing machining cycles.

FAQ

What materials is this insert intended for?
The VNMG160404-MP3 WPP20G insert is specified for machining steel (ISO group P) and is optimised for the heat and chip characteristics typical of those materials.

How does the MP3 chipbreaker affect productivity?
The MP3 chipbreaker shapes and evacuates chips reliably, which supports higher cutting parameters and reduces interruptions caused by poor chip control when using the WPP20G grade.

What does the 0° negative rake mean in practice?
A 0° negative rake provides a sturdy cutting edge that improves edge stability under load, offering a balance between tool life and surface quality for the intended turning applications.

Is this insert compatible with standard toolholders?
The rhombic 35° form and VNMG designation correspond to common turning insert standards, enabling use in compatible indexable holders designed for this geometry.
