SNMM120408-HU3 WPP20G turning insert — Tiger·tec Gold grade for Stahl, Walter Tools

A SNMM120408-HU3 WPP20G turning insert engineered for robust finishing and medium-turning of Stahl, offering a square 90° geometry and a controlled chipforming solution.

• Tiger·tec Gold coating for durable cutting
• Universal grade optimised for Stahl
• Square 90° geometry for stable cuts
• Corner radius 0.8 mm for repeatable finishes

Reliable chip control and extended tool life with modern coating

The WPP20G grade, part of the Tiger·tec Gold series, combines a wear-resistant coated carbide with a balanced microstructure to withstand the thermal and mechanical demands of machining Stahl. The coated structure reduces flank wear and improves edge stability, which in turn lengthens in-process life and lowers the cost per part. The HU3 chipbreaker is designed to deliver predictable chip shapes across a range of cutting parameters, reducing the risk of entanglement and improving machine uptime. For operations switching between finishing and light-medium turning, this insert supports consistency without frequent edge changes.

Geometry designed for process security and surface quality

The square 90° shape and corner radius 0.8 mm provide a rigid cutting edge that resists deflection in interrupted cuts and offers repeatable surface finish. The 0° (negative) relief angle supports robust edge strength when facing or turning sections with variable engagement, while the compact plate size maintains close tool-to-workpiece stability. These geometric choices make the insert especially suitable for fixtures and set-ups where runout and vibration are concerns, resulting in higher first-pass yield and reduced rework.

Practical benefits for workshop integration and productivity

With a focus on productive chip formation and broad material coverage for Stahl, this insert contributes directly to process efficiency. The coated grade helps to sustain cutting performance under elevated temperatures, enabling slightly higher cutting speeds or longer index intervals. For production environments that prioritise repeatability, the combination of a defined chipbreaker, consistent corner radius and a resilient coating reduces unplanned tool changes and supports predictable scheduling.

FAQ

What materials is this insert suited for?
The SNMM120408-HU3 WPP20G from Walter Tools is developed primarily for machining Stahl as specified by the WPP20G grade.

How does the Tiger·tec Gold coating improve performance?
The Tiger·tec Gold coating increases wear resistance and edge stability on the SNMM120408-HU3 WPP20G, which helps to extend index intervals and maintain surface quality under thermal loads.

Which chip shapes can be expected with the HU3 breaker?
The HU3 chipbreaker on this insert produces controlled, short to medium chips across typical turning parameters, reducing the risk of chip entanglement and improving process reliability.

Is the square 90° geometry suitable for facing operations?
Yes; the square 90° geometry combined with the 0.8 mm corner radius offers robust edge strength for facing and general turning tasks where rigidity and repeatability are important.
