SPMT120408-F55 WSP45G milling indexable insert by Walter Tools — Tiger‑tec Gold, P/M/S

SPMT120408-F55 WSP45G is a square 90° milling indexable insert designed for versatile machining of steel, stainless steel and heat‑resistant alloys in milling applications.

• Tiger‑tec Gold PVD coating for enhanced wear resistance
• Versatile for ISO groups P / M / S
• Chipbreaker F55 for controlled chip formation
• 11° relief angle and 0.8 mm corner radius

Increased productivity through a wear‑resistant grade

The combination of the Tiger‑tec Gold coating and the WSP45G grade allows for prolonged cutting performance and fewer index changes, which supports continuous production. The PVD multilayer coating improves abrasion resistance while preserving edge stability; this results in longer tool life and more predictable process windows. In practice, that means less machine downtime and a lower cost per component when compared with uncoated or lower‑performance grades. The chip control geometry reduces interruptions from built‑up edge and unstable chips, so cycle time remains consistent across a range of feeds and speeds.

Stable cutting geometry for reliable surface finish

A square 90° insert with an 0.8 mm corner radius offers a robust cutting edge that balances strength and surface quality. The medium tolerance class (M) contributes to reproducible seating and repeatable part accuracy in serial production. The chipbreaker F55 is tuned to evacuate chips efficiently during shoulder and face milling, which helps maintain a consistent contact zone and reduces vibration. For shops seeking reliable surface quality on transitional passes, this insert provides the mechanical stability needed to avoid micro‑chatter and to deliver a stable finish on workpiece shoulders and faces.

Broad material application and machining guidance

Engineered for ISO groups P / M / S, this grade is suitable for machining a wide range of workpiece materials: unalloyed and alloyed steel, stainless steel, and heat‑resistant superalloys or titanium. The insert’s geometry and coating are selected to address typical challenges such as heat generation and gummy chip formation in stainless steels, or the abrasive, high‑temperature conditions encountered with superalloys. For finishing operations select conservative feeds and higher spindle speeds with interrupted cuts minimised; for roughing, increase feed per tooth while monitoring chip pack‑up to exploit the grade’s toughness.

Practical advantages in the workshop

Because the insert is part of a well‑established Tiger‑tec Gold series, replacement and grade selection are straightforward for production environments. The ISO designation and clear grade marking simplify tool planning and inventory management. The square format provides four usable corners per indexable insert, supporting cost‑efficient turning of multiple surfaces before regrinding or disposal. For production planning, the predictable wear pattern of this insert aids tool life estimation and reduces surprise stoppages, contributing to smoother workflow and higher machine utilisation.

FAQ

How does the WSP45G grade perform on stainless steel?
The Walter Tools WSP45G grade, part of the Tiger‑tec Gold series, is formulated for stable chip formation and edge security when machining stainless steel, reducing built‑up edge and improving consistency in finish passes.

Which chipbreaker is fitted and what is its benefit?
The insert uses the F55 chipbreaker, which promotes controlled chip formation and efficient evacuation during both roughing and finishing, helping to maintain cutting stability and tool life.

What geometry details are relevant for programming?
Key geometry values: square 90° form, corner radius 0.8 mm and a relief angle of 11°, which should be considered when setting radial and axial depths of cut to balance strength and surface finish.

Is this insert suitable for titanium and superalloys?
Yes — the insert is designated for ISO group S, so it is suitable for heat‑resistant superalloys and titanium, benefiting from the grade’s toughness and thermal resistance under demanding conditions.

How many usable cutting edges are available per insert?
The square 90° format provides four indexable corners, enabling multiple re‑indexes before replacement and improving cost efficiency per edge.
