VCMT160412-RM4 WSM30S – Turning indexable insert with Tiger·tec Silver coating and RM4 chipbreaker (Walter Tools)

The VCMT160412-RM4 WSM30S is a rhombic 35° turning insert engineered for stable, productive machining of stainless steels and heat-resistant superalloys in demanding turning operations

• Tiger·tec Silver coating for thermal stability
• RM4 chipbreaker for reliable chip control
• Suitable for stainless steels and superalloys
• 1.2 mm corner radius for robust edge life

Consistent performance for difficult materials

The Tiger·tec Silver grade WSM30S delivers a balance of heat resistance and edge stability tailored to challenging materials. Designed for ISO groups M (stainless steels) and S (superalloys and titanium), the carbide-based, coated grade supports steady chip formation and reduces the risk of built-up edge. For production environments this means fewer interruptions, more predictable tool changes and improved process reliability through stable cutting-edge behaviour.

Geometry that reduces machining risk and improves repeatability

A rhombic 35° form combined with a 7° relief angle and a 1.2 mm corner radius provides a controlled cutting action and robust corner strength. The insert geometry reduces cutting forces on interrupted cuts and supports consistent surface finishes on cylindrical and profiling tasks. These dimensions help maintain tool life under moderate to heavy feed conditions while preserving repeatable component tolerances and minimising vibration-induced errors.

Coating and chip control that boost throughput

The RM4 chipbreaker is engineered to produce short, controlled chips in a range of turning depths, improving evacuation in both wet and dry machining. Coupled with the Tiger·tec Silver coating, the combination enhances temperature management at the cutting zone and prolongs the life of the cutting edge. For manufacturers this translates into higher effective spindle time and reduced scrap rates, particularly when machining heat-prone stainless alloys.

Practical compatibility and handling in workshop workflows

This insert is supplied in the standard VCMT format and is compatible with common toolholder systems designed for rhombic inserts of this size. The designation VCMT160412-RM4 indicates nominal 16 mm plate size and the thickness code 04, facilitating straightforward selection from tooling lists. The coated, indexable design allows multiple indexings per insert, reducing tooling costs and simplifying inventory management for production and job-shop settings.
