CNMG120404-FM5 WSM20S turning indexable insert by Walter Tools — Tiger·tec Silver coated, FM5 chipbreaker

A CNMG120404-FM5 WSM20S turning insert designed for secure chip control and edge stability when machining stainless steels and high-temperature alloys, suited to a wide range of turning applications

• Tiger·tec Silver coated carbide grade WSM20S
• FM5 chipbreaker for controlled chip formation
• Rhombic 80° geometry for versatile turning

Consistent performance for challenging materials

The combination of a Tiger·tec Silver coating and the WSM20S grade provides a balanced response to the demands of stainless steels and heat-resistant superalloys. The coating increases thermal resistance while the substrate supports a stable cutting edge, which results in more predictable tool life under difficult cutting conditions. For production environments this means fewer unscheduled insert changes and a steadier process, contributing directly to improved throughput and lower overall tooling costs. The rhombic 80° geometry further ensures flexibility across finishing and medium-turning operations without sacrificing edge strength.

Better chip control and edge security improve cycle times

The FM5 chipbreaker is engineered to produce short, manageable chips even when cutting ductile or gummy materials. Controlled chip formation reduces rework, minimises toolholder interference and enhances operator safety at the machine. The 0° negative relief promotes robust support of the cutting edge, making the insert particularly reliable during interrupted cuts and under heavy load. These technical characteristics translate into a practical advantage on the shop floor: fewer stoppages for chip-related faults and a more stable surface quality on the workpiece.

Practical benefits for tool management and process reliability

With a 0.4 mm corner radius and a standard CNMG profile, the insert integrates into common tooling systems while offering predictable results in repetitive production runs. The tolerance class M underlines consistent dimensional accuracy, which simplifies indexable insert replacements and reduces set-up time. The coated carbide grade supports a broad material coverage (ISO groups M and S) so that one insert type can serve multiple applications, improving inventory efficiency and purchasing simplicity for manufacturing operations.

FAQ

Is this insert suitable for stainless steels and high-temperature alloys?
Yes. The CNMG120404-FM5 WSM20S insert features the Tiger·tec Silver grade designed specifically for stainless steels (ISO group M) and heat-resistant superalloys (ISO group S), providing thermal resistance and stable cutting edges.

What does the FM5 chipbreaker deliver in practice?
The FM5 chipbreaker on this Walter Tools insert produces short, controllable chips and supports reliable chip evacuation, which reduces machine downtime and improves surface finish consistency.

Can the insert handle interrupted cuts and heavier feeds?
The negative relief angle and the robust edge support of the CNMG120404-FM5 make the insert well suited to interrupted cuts and demanding operations where edge stability is essential.

How does the Tiger·tec Silver coating affect tool life?
Tiger·tec Silver increases heat and wear resistance of the coating system, helping to maintain a sharper edge for longer periods during the machining of tough-to-cut materials, thus enhancing overall productivity.
