SPMT120408-F55 WSM35G – square 90° milling insert, Tiger·tec Gold coating | Walter Tools

SPMT120408-F55 WSM35G is a square milling insert designed for heavy‑duty machining of stainless steels and heat‑resistant alloys, offering robust cutting edges and reliable chip control.

Tiger·tec Gold coating for heat resistance
Optimised F55 chipbreaker for secure chip control
Square 90° form with 0.8 mm corner radius
Suitable for stainless and superalloys (ISO M, S)

Improved process security when machining tough alloys

The WSM35G grade, combined with the Tiger·tec Gold coating, is engineered for stability at high temperatures and reduced edge wear when working with stainless steels and superalloys. The coating technology supports a stable cutting edge and controlled wear progression, which translates into longer tool life and fewer insert changes. The insert’s 11° relief angle contributes to predictable cutting forces, while the 0.8 mm corner radius offers a balance between edge strength and surface finish. This combination reduces the risk of built‑up edge formation and supports consistent component tolerances during continuous production.

Consistent chip control and surface quality under demanding conditions

The dedicated F55 chipbreaker is tailored to the cutting geometry and material groups ISO M and S, promoting regular chip formation even at elevated cutting temperatures. Secure chip control helps to avoid entanglement and secondary machining steps, supporting uninterrupted cycle times and improved workplace safety. The square form factor (90°) ensures robust engagement with the workpiece and allows favourable cutting parameters for finishing passes. As an indexable component, the insert helps maintain surface quality across multiple edges, ensuring reproducible results batch after batch.

Efficiency gains through indexable design and multiple cutting edges

A square insert provides several usable corners, enabling rapid rotation to a fresh edge and lowering per‑edge costs compared with solid tools. The indexable design reduces downtime for tool changes and simplifies inventory management in mixed‑material production. For jobs that demand both robustness and repeatability, the combination of Tiger·tec Gold technology and the WSM35G grade delivers a pragmatic balance between performance and economy, making it well suited for workshops and production lines that process challenging materials. Walter Tools’ manufacturing standards support consistent geometry and tolerance classes to aid tool‑holder compatibility and predictable tool life.

FAQ

What materials is this insert suitable for?
The SPMT120408‑F55 WSM35G insert is designed primarily for stainless steels (ISO M) and heat‑resistant superalloys or titanium (ISO S), taking advantage of the Tiger·tec Gold coating for thermal stability.

How does the F55 chipbreaker affect performance?
The F55 chipbreaker promotes predictable chip formation and evacuation under the thermal loads typical of machining stainless and superalloy materials, improving surface quality and reducing downtime due to chip issues.

How many cutting edges are available per insert?
The square 90° geometry offers multiple usable cutting corners; rotating to a fresh edge restores cutting performance without replacing the insert, which supports cost‑effective production.

What benefits does the Tiger·tec Gold technology provide?
Tiger·tec Gold coating increases heat resistance and wear performance for the WSM35G grade, helping to maintain a stable cutting edge during prolonged operations in demanding materials.

Is this insert compatible with Walter Tools tool holders?
The SPMT120408‑F55 WSM35G insert is manufactured to standard indexable insert dimensions and tolerance classes; compatibility with Walter Tools or other standard milling holders should be verified against holder specifications.
