CCMT120408-FM4 WSM20S – Boring and turning indexable insert with FM4 chipbreaker (Walter Tools)

The CCMT120408-FM20S insert is a rhombic 80° indexable cutting tool optimised for turning and boring of stainless steels and heat‑resistant superalloys, delivering secure chip control and edge stability in demanding conditions.

• Tiger·tec Silver coating for temperature resistance
• FM4 chipbreaker for reliable chip control
• Rhombic 80° CCMT geometry, 0.8 mm corner radius

Consistent edge stability for reduced regrinds and interruptions

The combination of the FM4 chipbreaker and the rhombic 80° geometry gives predictable chip formation and stable cutting performance, which reduces unexpected tool changes and machine downtime. A 0.8 mm corner radius and 7° clearance increase resistance to edge chipping and distribute cutting forces more evenly, resulting in a more durable cutting edge under the thermal and mechanical loads typical when machining stainless steels and similar materials. This stability translates directly into fewer process interruptions and improved throughput.

Heat resistance and wear control for demanding alloys

The Tiger·tec Silver coating applied to the WSM20S grade is engineered to withstand elevated temperatures and to limit flank wear when processing alloys that generate high heat. For machinists facing workpieces that tend to harden, build up on the edge, or produce stringy chips, the coated WSM20S grade supports controlled wear progression and keeps surface finish consistent over longer tool life. The result is a lower tool consumption rate and reduced need for frequent regrinding or replacements.

Improved productivity through predictable performance

Using a purpose‑matched, coated insert reduces process variability. The combination of the WSM20S grade and the Tiger·tec Silver technology promotes a repeatable cutting action, which supports consistent component quality and lessens the burden on secondary operations. With better wear behaviour and reliable chip evacuation, cycle times can become more predictable and job scheduling more efficient—advantages that directly contribute to improved shop floor productivity and cost effectiveness.

Practical application guidance for shops and OEMs

This indexable insert is suitable for turning and light boring tasks where material ranges include stainless steels and heat‑resistant alloys. Its geometry and chipbreaker are designed for medium‑to‑heavy interrupted cuts as well as continuous operations where chip control is critical. For specific machine and material pairings, Metav Werkzeuge’s consultants can supply cutting‑parameter guidance and integration advice to match the insert to holders and machines. Small adjustments to feed and depth of cut, combined with appropriate coolant strategies, will help to fully exploit the insert’s advantages.
