VCMT160408-FM4 WMP20G — Turning insert VCMT160408-FM4 WMP20G for rostfreier Stahl — Walter Tools

VCMT160408-FM4 WMP20G is a coated turning insert engineered for medium to robust machining of rostfreier Stahl, combining Tiger‑tec Gold technology with an FM4 chipbreaker and a 7° clearance angle.

• Positive cutting-edge stability with Tiger‑tec Gold
• Optimised chip control FM4 geometry
• Rhombic 35° shape for versatile turning
• 0.8 mm nose radius for consistent surface finish

Faster, more reliable machining of rostfreier Stahl

The VCMT160408-FM4 WMP20G insert uses Tiger‑tec Gold coating on a coated carbide substrate to resist thermal and abrasive wear during challenging stainless‑steel operations. The WMP20G grade is tailored for rostfreier Stahl, where workpiece toughness and heat generation demand a stable cutting edge. As a result, cycle times are controlled and the need for frequent tool changes is reduced, which improves overall shop productivity. The combination of coating and grade supports predictable performance even under interrupted cuts, reducing scrap and rework.

Stable chip formation and extended tool life

Equipped with the FM4 chipbreaker, this insert provides chip control that prevents long, stringy chips and supports continuous, safe machining. The chipbreaker geometry encourages segmented chip flow and reduces heat concentration at the cutting edge, which contributes to longer tool life and consistent surface quality. For production environments with mixed batch sizes, this stability translates into fewer stoppages, reduced tool inventory turnover and improved process reproducibility.

Geometry that balances versatility and finish

The rhombic 35° form with a 0.8 mm nose radius and a 7° clearance angle enables a balance between robustness and finish capability. The acute approach angle supports lower cutting forces for fine finishing, while the nose radius helps achieve consistent surface results on complex contours. Its VCMT format and moderate plate size make it suitable for a wide range of standard toolholders, allowing fast changeover and flexible use across turning operations.

Practical selection and machining advice

This insert is intended for medium to robust turning operations in rostfreier Stahl where both durability and surface integrity matter. Selection of cutting parameters should favour moderate feed rates to match the 0.8 mm nose radius and to exploit the FM4 chip control. For specific machining data, toolholder compatibility or to verify suitability for a particular stainless‑steel grade, consult Metav Werkzeuge’s application specialists who can recommend cutting speeds, feeds and depth of cut to optimise process security and economy.

FAQ

Is this insert suitable for machining stainless steels? Yes. The VCMT160408-FM4 WMP20G insert is designed specifically for rostfreier Stahl and supports secure chip formation and stable cutting under the typical conditions of stainless‑steel turning.

What applications suit this insert best? Medium to robust turning operations where a balance of tool life and surface quality is required; the FM4 chipbreaker and 0.8 mm nose radius make it appropriate for both semi‑finishing and finishing passes on rostfreier Stahl.

Which toolholders are compatible with this insert format? The VCMT form fits standard VCMT‑type turning toolholders; compatibility should be confirmed with the holder specifications and the intended cutting parameters for safe clamping and correct shear geometry.

How does the chipbreaker influence machining performance? The FM4 chipbreaker directs chip flow to reduce heat concentration and avoid long, entangling chips, resulting in more consistent machining, improved safety and reduced downtime for chip clearing.

Does the Tiger‑tec Gold technology improve wear resistance? Yes. Tiger‑tec Gold coating enhances thermal and abrasive resistance of the coated carbide substrate, contributing to longer tool life and stable cutting-edge behaviour in demanding rostfreier Stahl operations.
