VCMT160404-FM4 WMP20S – Turning indexable insert, Tiger·tec Silver, rhombic 35° (Walter Tools)

The VCMT160404-FM20S WMP20S is a rhombic 35° turning insert designed for robust and repeatable machining of rostfreier Stahl, offering secure chip control and extended edge life in medium to demanding applications.

• Tiger·tec Silver coating for improved edge life
• FM4 chipbreaker for secure chip control
• Rhombic 35° geometry for versatile turning
• 0.4 mm corner radius for fine surface finish

Reliable performance for rostfreier Stahl applications

The combination of the Tiger·tec Silver coating and the WMP20S carbide grade delivers a finely tuned balance between wear resistance and toughness for rostfreier Stahl. The coated hardmetal construction supports stable cutting edges under elevated temperatures and the tendency of these alloys to form built-up edges. The integrated FM4 chipbreaker promotes controlled chip segmentation, which reduces clogging in the cut and enhances process security. These features translate into fewer unplanned tool changes and more consistent part quality during production runs.

Improved productivity and predictable tool life

The rhombic 35° insert geometry and the 0.4 mm corner radius provide a flexible foundation for both finishing and light turning operations while maintaining low vibration and surface integrity. The 7° clearance angle helps to limit rubbing on the flank face, thereby reducing thermal loading on the cutting edge. Together, the geometry and the coated grade contribute to longer edge life and a reduced need for frequent insert indexing, which supports higher machine uptime and a more favourable cost per part over time.

Practical integration and machining benefits

As a standard indexable insert form, this element fits common VCMT toolholders and allows straightforward replacement without special adapters. The FM4 chipbreaker is designed to assist chip evacuation across a range of feeds, lowering the risk of entanglement in automated or multi-axis turning setups. For shop-floor teams, the result is a more consistent machining cycle and easier process tuning: insert selection and chipbreaker choice directly influence feed selection and coolant strategy, so pairing this insert with appropriate cutting data delivers measurable gains in operational stability and part finish.

Material and process suitability explained

The WMP20S grade, as implemented in the Tiger·tec Silver series, specifically targets the machining challenges of rostfreier Stahl: high toughness, tendency to form built-up edges and heat retention at the cutting zone. The coated carbide base offers a protective layer that helps prevent premature flank wear and maintains cutting-edge integrity under intermittent or continuous cutting conditions. When combined with the FM4 chip control geometry, the insert reduces the frequency of surface defects associated with unstable chips and supports a predictable finishing strategy.
