VCMT160404-MM4 WMP20S — indexable turning insert, Tiger·tec Silver, Walter Tools

The VCMT160404-MM4 WMP20S is a coated carbide indexable insert designed for medium to robust turning of rostfreier Stahl, offering controlled chip formation and a geometry optimised for consistency in industrial turning applications

• Tiger·tec Silver coated carbide
• MM4 chipbreaker for stable chips
• Rhombic 35° form for versatile turning
• 7° clearance angle for secure cutting

Higher throughput through coated carbide technology

The Tiger·tec Silver coating on this insert provides a balanced surface hardness and thermal resistance that supports longer cutting intervals and fewer interruptions. By combining a wear-resistant coating with a robust substrate grade, the insert promotes stable chip formation and reduced edge build-up when machining rostfreier Stahl. The result is a measurable improvement in process reliability and a reduction in rework cycles, which directly benefits production flow in batch and serial machining.

Geometry that improves surface quality and tool life

The rhombic 35° shape and a 0.4 mm corner radius deliver a compromise between strength and accessibility for internal and external turning operations. The modest clearance of 7° reduces rubbing while maintaining a secure cutting edge, which helps to preserve the insert’s edge integrity under intermittent cuts. These geometrical choices support consistent surface finishes and minimise the risk of unexpected tool failure, translating into predictable machining results and lower overall tooling costs.

Chip control and application guidance for demanding materials

Equipped with the MM4 chipbreaker, the insert channels swarf reliably even under higher heat generation typical of rostfreie Stähle. The breaker geometry assists in forming short, controllable chips that ease evacuation and protect both workpiece and machine. The grade WMP20S is specified for rostfreie Stähle under medium to heavy conditions: it addresses tendencies to work-harden and build-up, helping maintain cutting stability during longer cuts. Choose appropriate feeds and cutting depths for the component material and setup to benefit from the insert’s full capabilities.

Durable brand performance and practical deployment

Originating from Walter Tools’ Tiger·tec Silver series, this insert aligns with industrial expectations for repeatable performance and consistent tool life. The combination of a coated carbide substrate and an optimised chipbreaker supports predictable maintenance cycles and makes the insert suitable for production-oriented environments.
