SCMT120408-FM6 WSM20S square turning insert, Tiger·tec Silver – Walter Tools

A SCMT120408-FM6 WSM20S indexable turning insert engineered for secure chip control and reliable performance when machining stainless steel and high-temperature alloys

• Tiger·tec Silver coated carbide grade WSM20S
• Square 90° insert with 0.8 mm nose radius
• 7° relief angle for controlled cutting forces
• FM6 chipbreaker for improved chip formation

Consistent cutting performance with difficult-to-machine alloys

The combination of the WSM20S grade and the Tiger·tec Silver coating delivers a balanced mix of hardness and toughness, optimised for stainless steels and superalloys. The coating technology reduces flank wear and improves heat resistance, which in turn supports a stable cutting edge under thermally demanding conditions. For process planners, this means a lower rate of edge deterioration and more predictable tool life; the insert’s engineered substrate and coating interaction promote reliable chip breaking even when material properties vary. The technical choice of a coated cemented carbide grade rather than uncoated carbide is intended to reduce built-up edge and extend productive cutting time.

Geometry tuned for precise turning and surface quality

The square 90° insert form with a 0.8 mm corner radius and 7° relief angle provides a robust cutting geometry that balances strength and surface finish. A larger nose radius contributes to improved surface quality by distributing cutting forces over a greater contact area, while the moderate relief angle helps keep cutting forces controlled during interrupted or continuous cuts. The FM6 chipbreaker is designed to generate short, controllable chips in tough materials, reducing the risk of entanglement and improving machine uptime. Thickness designation and insert size ensure compatibility with standard toolholders and predictable positioning in the tool assembly.

Production advantages and process security for workshops

Adopting this insert supports repeatable results and reduced cycle-time loss through dependable chip control and wear resistance. The WSM20S grade’s emphasis on stable chip formation and edge life provides demonstrable economic benefits in batch production and maintenance-sensitive environments. Toolroom managers gain greater process security due to consistent performance across batches of stainless material and heat-resistant alloys. Technical teams benefit from straightforward integration into existing turning systems and from fewer unscheduled tool changes, contributing to overall improved throughput and component quality.

FAQ

Which materials is this insert suitable for?
The SCMT120408-FM6 WSM20S insert is intended for stainless steels and heat-resistant superalloys (ISO groups M and S), where the Tiger·tec Silver coating and WSM20S grade support stable chip formation and edge life.

What effect does the 0.8 mm corner radius have on machining?
A 0.8 mm corner radius increases contact area for improved surface finish and reduced peak forces, which helps the insert maintain dimensional consistency during turning operations.

How does the FM6 chipbreaker improve production reliability?
The FM6 chipbreaker promotes short, controllable chips when machining tough materials, reducing the likelihood of chip-related interruptions and easing chip evacuation in automated setups.

Is this insert compatible with standard toolholders?
The square 90° form and the SCMT designation correspond to common indexable insert standards, making the insert compatible with appropriately sized standard turning toolholders.

What distinguishes the Tiger·tec Silver series for workshop use?
Tiger·tec Silver provides enhanced thermal resistance and reduced flank wear compared with conventional coatings, resulting in longer useful cutting life and steadier process performance for demanding materials.
