VCMT110302-FM4 WSM30S indexable turning insert – 7° clearance, Rhombic 35°, Walter Tools

VCMT110302-FM4 WSM30S is a rhombic‑35° indexable turning insert designed for heavy and heat‑resistant materials, providing a balance of edge strength and controlled chip flow for industrial turning applications

• Tiger‑tec Silver coating for tough materials
• Grade WSM30S for stainless steels and superalloys
• FM4 chipbreaker for secure chip control
• Rhombic 35° VCMT form with 0.2 mm radius

Stable cutting performance where heat and toughness matter

The Tiger‑tec Silver coating combined with a coated‑carbide substrate gives a measurable improvement in thermal resistance and wear behaviour. This grade, WSM30S, is formulated to maintain a stable cutting edge under the high temperatures and adhesive tendencies typical of stainless steels and superalloys. The result is extended tool life and fewer interruptions for insert changes, which supports continuous, predictable production cycles and reduces overall machining cost per component.

Precise geometry for consistent chip control and surface quality

A Rhombus 35° geometry with 7° clearance and a 0.2 mm corner radius provides an advantageous contact angle for turning operations that demand good surface finish and dimensional repeatability. The FM4 chipbreaker is configured to form short, manageable chips in tough materials, improving swarf handling and protecting the workpiece from built‑up edge. This combination helps achieve consistent part quality without sacrificing cutting efficiency.

Suited to demanding workpiece materials and robust process windows

The specification supports machining in the ISO groups M and S — explicitly stainless steels and heat‑resistant superalloys/titanium. The grade behaviour favours secure chip formation and edge strength where conventional grades wear prematurely. For shops tackling mixed batches of stainless components or high‑temp alloys, this insert widens the stable cutting envelope and reduces the need for frequent grade changes.

Practical benefits for production and tool management

Using the VCMT110302-FM4 geometry in the Tiger‑tec Silver series simplifies inventory strategy: a single insert family covers a broader range of applications, lowering variant counts while delivering reliable performance. The compact 0.2 mm corner radius helps when close tolerances and controlled cutting forces are required, and the defined tolerance class M supports interchangeability in toolholders and automated tool‑change systems, improving uptime and process reproducibility.
