SPMW120408T-A27 WPP35G milling indexable insert — Tiger·tec Gold, for steel | Walter Tools

The SPMW120408T-A27 WPP35G is a square milling indexable insert designed for efficient steel machining, combining a Tiger·tec Gold coated carbide grade with a controlled A27 chipformer.

• Tiger·tec Gold coating for extended tool life
• Suited for machining steel (ISO P)
• Square 90° shape with 0.8 mm corner radius
• A27 chipformer for controlled chip flow

Longer tool life and reliable wear resistance

The combination of the Tiger·tec Gold coating and the WPP35G coated carbide substrate delivers a clear technical advantage for steel machining. The coating reduces flank and crater wear under the thermal and mechanical loads typical of ISO P materials, which results in longer tool life and more predictable tool-change intervals. For production environments this means higher uptime and fewer interruptions. The grade balances wear resistance and toughness, making it suitable for a range of general-purpose and semi-finishing strategies while maintaining consistent performance.

Geometry that supports surface quality and stability

The square 90° insert form and the 0.8 mm corner radius provide stable cutting engagement and repeatable edge performance. The 11° relief angle is matched to the geometry to reduce rubbing and minimise heat build-up at the cutting edge, which helps to preserve surface finish and dimensional stability. The integrated A27 chipformer controls chip shape and evacuation, reducing the risk of re-cutting and promoting steady cutting forces. Tolerance class M ensures a reproducible fit in standard toolholders for reliable indexing and repeatability across production batches.

Practical process benefits and application scope

Designed for steel applications (ISO P), this indexable insert fits common milling toolholders and supports straightforward parameter selection for slotting, shoulder milling and light ramping passes. The solid, coated-carbide construction supports high material removal rates with reduced edge wear. If there is uncertainty about specific cutting data or holder compatibility, Metav Werkzeuge provides technical recommendations and cutting-parameter tables to support process integration and optimisation, ensuring the insert performs in line with shop-floor targets.

FAQ

What materials is this insert intended for?
This insert is intended primarily for machining steel (ISO P); the WPP35G grade and Tiger·tec Gold coating are optimised for typical heat and chip formation when cutting steel.

How does the A27 chipformer affect machining?
The A27 chipformer shapes and breaks chips reliably, improving evacuation and reducing the chance of clogging or re-cutting during milling with the SPMW120408T-A27 WPP35G insert.

What edge geometry ensures consistent surface finish?
The square 90° form with a 0.8 mm corner radius and an 11° relief angle contributes to stable cutting engagement and consistent surface quality when used in appropriate toolholders.

Is this insert compatible with standard toolholders?
Yes, the insert is designed to fit standard toolholders for square inserts; tolerance class M ensures reproducible seating and reliable indexing in common milling systems.
