SPGT1204EDR-F55 WSM35G Fräswendeschneidplatte — Tiger·tec Gold grade, for rostfreier Stahl and high-temperature alloys | Walter Tools

The SPGT1204EDR-F55 WSM35G is a square 90° milling insert engineered for heavy-duty finishing and semi-finishing of rostfreier Stahl and heat-resistant superalloys where edge stability and predictable chip formation are essential

• Tiger·tec Gold coating for high wear resistance
• Optimised for rostfreier Stahl and superalloys
• Square 90° insert, 12 mm size for stable indexing
• F55 chipbreaker for secure chip control
• 11° clearance angle for reliable cutting performance

Consistent productivity in challenging materials

The insert uses the WSM35G cutting grade within the Tiger·tec Gold family to deliver extended tool life when machining rostfreier Stahl and nickel‑based alloys. The multilayer coating and tailored carbide substrate reduce flank wear and support stable chip formation, which lowers the frequency of tool changes and contributes directly to higher machine uptime. For workshop managers and process engineers, this means greater predictability in cycle times and fewer interruptions during critical production runs.

Secure chip control and improved surface results

The integrated F55 chipbreaker is developed to produce short, controllable chips in hard-to-machine materials, reducing the risk of built-up edge and surface damage. With a square 90° cutting form, the insert provides a robust corner for interrupted cuts and face-milling operations, improving resistance to impact and edge chipping. As a result, the machining process is more stable and the requirement for secondary finishing is often reduced, delivering clear efficiency gains.

Geometry that simplifies setup and increases repeatability

Key dimensions and angles are chosen to balance strength and accessibility: the insert is offered in a 12 mm size with a 04 thickness designation and an 11° clearance angle, running to tolerance class G. These specifications facilitate consistent seating in standard indexable milling cutters and reduce variation between tool changes. Clear, standardised geometry helps maintain process repeatability across batches and operators, which supports quality assurance and reduces scrap rates.

Grade selection and practical application advice

The WSM35G grade is recommended where heat resistance and edge stability are decisive—typical applications include rostfreier Stahl and turbine alloys. The coated carbide substrate is optimised to resist thermal softening and mechanical wear; when combined with the F55 chip control, the result is productive machining with predictable tool life. For tailored recommendations on feeds, speeds and coolant strategies, Metav Werkzeuge’s technical advisors can provide process parameters adjusted to machine capability and workpiece specifications.

FAQ

Which materials is this insert designed to machine?
The SPGT1204EDR-F55 WSM35G insert is formulated for machining rostfreier Stahl (ISO group M) and heat‑resistant superalloys/titanium (ISO group S) where thermal stability and edge security are required.

What advantage does the F55 chipbreaker provide?
The F55 chipbreaker promotes short, uniform chips and reduces built‑up edge; when used with the WSM35G grade it supports consistent surface finish and safer chip evacuation in demanding materials.

How does the Tiger·tec Gold series improve performance?
Tiger·tec Gold coating increases wear resistance and thermal stability; in combination with the WSM35G substrate the insert maintains cutting-edge integrity over longer cycles, improving productivity with fewer indexing events.

Is the square 90° geometry suitable for interrupted cuts?
Yes, the square 90° form delivers a strong corner edge that is well suited to interrupted cuts and face‑milling, offering improved resistance to impact and chipping during heavy engagement.
