CCMT09T308-RM4 WSM30S — Turning and Boring Indexable Insert, Tiger·tec Silver (Walter Tools)

The CCMT09T308-RM4 WSM30S is an indexable insert designed for turning and boring applications, optimised for machining stainless steels and heat-resistant superalloys.

• Tiger·tec Silver coating for heat resistance
• RM4 chipbreaker for controlled chip formation
• Suitable for stainless steels and superalloys

Exceptional performance for demanding materials

This indexable insert is manufactured in the WSM30S grade within the Tiger·tec Silver family, delivering enhanced heat resistance and wear stability when machining challenging workpiece materials. The coated carbide composition supports secure chip control and a stable cutting edge under high thermal loads, which reduces the risk of built-up edge and extends effective tool life. For production environments where consistent results and reduced rework matter, this geometry-grade combination promotes process reliability and predictable performance.

Precision geometry that improves surface quality and repeatability

The rhombic 80° shape combined with a 0.8 mm nose radius and a 7° free angle provides a balance between edge strength and accessibility for profile work. The RM4 chipbreaker is optimised for stable chips and predictable evacuation, helping to maintain surface finish in semi-finishing and finishing passes. The insert’s T3 thickness and size designation ensure mechanical rigidity in the toolholder, which translates into improved dimensional repeatability and fewer rejects in serial production.

Productivity through thermal stability and reduced downtime

Thanks to the Tiger·tec Silver coating technology, the cutting edge retains integrity at elevated temperatures common when machining stainless steels and heat-resistant alloys. This thermal resilience allows for more aggressive cutting parameters without compromising edge life, leading to reduced cycle times and longer periods between indexings. The combination of coating and geometry supports high process security and contributes to lower overall machining costs in continuous production runs.

Versatile application scope and handling guidance

Classified for ISO groups M and S, the insert is suitable primarily for stainless steels and, depending on tool geometry, for heat-resistant superalloys and titanium. The rhombic geometry is particularly useful where access and turning versatility are required. When integrating the insert into a turning or boring operation, select cutting speeds and feeds with the material’s heat conductivity in mind; the grade is aimed at maintaining stable chip formation and minimising edge build-up during extended cuts.
