SEHT1204AFN WSP45G – Milling insert (square 90°), Tiger·tec Gold, 20° relief (Walter Tools)

The SEHT1204AFN WSP45G is a square milling insert engineered for general milling of Stahl, rostfreier Stahl and high-temperature alloys, combining a robust PVD coating with stable cutting-edge performance for demanding industrial applications.

• Tiger·tec Gold PVD coating for edge stability
• Suitable for Stahl, rostfreier Stahl and superalloys
• 20° relief angle for secure chip control
• Square 90° form, size 12, tolerance class H

Maximise process reliability with a proven coating system

The Tiger·tec Gold coating and the PVD-coated carbide substrate deliver a balance of wear resistance and edge toughness that supports sustained productivity. The coating reduces thermal and adhesive wear during milling, so the tool maintains a stable cutting edge over longer cycles. For industrial production this means fewer tool changes and more consistent surface quality, translating directly into improved uptime and a lower cost per component.

Broad material range explained for straightforward selection

Designed for the P/M/S material classes, the insert supports machining of P (Stahl), M (rostfreier Stahl) and S (superalloys and titanium). In practice this means the same grade can be used across common shop tasks—from roughing and semi-finishing in unalloyed or alloyed Stahl to more demanding cuts in rostfreier Stahl and heat-resistant alloys—reducing tooling complexity. The chemistry and microstructure of the grade aid secure chip formation where temperatures and adhesion are typically higher.

Geometry and tolerance for consistent part accuracy

The square 90° insert geometry provides robust edge support for face and shoulder milling operations, while the 20° relief angle assists controlled chip flow and reduces built-up edge on difficult-to-cut materials. The size 12 dimension and tolerance class H ensure repeatable seating and concentricity in standard milling cutters, enabling predictable cutting conditions and reliable edge life—key factors for process planning and toolpath optimisation.

Practical benefits for workshop efficiency

By combining a versatile grade with a consistent insert geometry, this milling insert reduces tool inventory and simplifies operation planning. The PVD-coated grade supports both durability and surface finish objectives, helping to achieve target tolerances with fewer passes. For teams aiming to increase throughput without compromising component quality, the insert offers a pragmatic route to lower cycle times and improved reproducibility.
