SDMT120425-F57 WSP45G square milling insert – Tiger‑tec Gold, for P/M/S applications (Walter Tools)

SDMT120425-F57 WSP45G is a square 90° indexable milling insert engineered for high‑productivity milling of steel, stainless steel and heat‑resistant alloys

• Tiger‑tec Gold PVD grade WSP45G
• Square 90° insert, 2.5 mm corner radius
• Suitable for steel, stainless and superalloys
• 15° relief angle for stable cutting

Consistent wear resistance for longer tool life

The Tiger‑tec Gold coating is a PVD‑based system optimised for milling, offering a balance between hardness and toughness. This combination reduces flank and crater wear under the high temperatures typical of milling processes, resulting in improved tool life and fewer insert changes. The WSP45G grade is specified for versatile performance across a broad range of steels and heat‑resistant materials; its coated carbide substrate supports secure edge retention during repeated passes. For production environments this translates into predictable cycle times and a reduction in downtime related to tool management.

Geometry that increases process stability and surface quality

A square 90° plate with a 2.5 mm corner radius delivers high edge strength for interrupted cuts and heavy engagement typical of shoulder milling. The 15° relief angle reduces rubbing at the flank while maintaining support behind the cutting edge, which helps to avoid built‑up edge and to produce a consistent surface finish. The insert form and edge preparation suit both roughing and semi‑finishing operations where stability and repeatability are decisive. In practise, the geometry lowers the risk of premature edge failure and supports higher feed rates with maintained surface integrity.

Versatile grade for demanding materials and controlled chip formation

Designed for materials classified under ISO groups P, M and S, this insert handles unalloyed and alloyed steel, stainless steel and high‑temperature superalloys and titanium components. The WSP45G grade promotes stable chip formation even where heat dissipation is limited, supporting safer machining of materials that tend to work‑harden or strain‑soften. Where process security and consistent reproducibility are required, the combination of coated carbide and optimised chipbreaker (F57) contributes to smoother swarf flow, reduced recutting and more consistent surface results on each workpiece.
