SDMW1204AZN-A57 WKP25S – Indexable milling insert, Tiger‑tec Silver, square 90° (Walter Tools)

The SDMW1204AZN-A57 WKP25S is an indexable milling insert engineered for productive chip formation and high process stability when machining steel and cast iron in general milling operations.

• Tiger‑tec Silver coating
• WKP25S grade for steel and cast iron
• Square 90° insert form
• Chipbreaker A57 for controlled chips

Consistent, productive performance on steel and cast iron

The combination of the Tiger‑tec Silver coating and the WKP25S carbide grade ensures consistent cutting performance under the thermal and mechanical demands of machining steel (P) and cast iron (K). The coating reduces abrasive wear and helps maintain a stable cutting edge, while the grade is tuned for the typical heat generation and chip behaviour encountered in these material groups. This results in longer tool life and fewer insert changes, supporting uninterrupted production cycles.

Reliable tool life through coated carbide technology

A coated carbide substrate offers a balance between toughness and hardness: the substrate absorbs shock while the coating resists abrasive wear. The coated carbide construction of this insert improves edge retention in mixed-production environments and reduces the frequency of regrinds. The A57 chipbreaker contributes to repeatable, short chips that are easier to evacuate, which in turn lowers the risk of built-up edge and surface damage on the workpiece.

Machine-friendly geometry for efficient milling and secure seating

The square 90° geometry with a 15° relief angle provides a robust cutting edge and flexibility for different milling strategies, including face milling and shoulder cuts where a strong corner is required. The designation reflects a standard form that fits common toolholders for solid and modular milling cutters. The tolerance class M supports consistent seating and repeatable positioning, reducing setup time and increasing process reliability.

FAQ

What materials is this insert suitable for?
The SDMW1204AZN-A57 WKP25S insert is specified for steel (P) and cast iron (K) applications and is engineered to manage the typical chip and wear behaviour of those groups.

What does the A57 chipbreaker do?
The A57 chipbreaker shapes chip formation to produce short, controlled chips; on the SDMW1204AZN-A57 WKP25S this supports safer evacuation and more consistent surface finishes during milling.

How does the Tiger‑tec Silver coating benefit machining?
The Tiger‑tec Silver coating on the insert reduces abrasive wear and improves heat resistance, which helps to extend edge life and maintain process stability in mixed production environments.

Is this insert compatible with standard toolholders for square inserts?
Yes, the square 90° form of the SDMW1204AZN-A57 WKP25S matches common milling cutter pockets for square inserts; tolerance class M supports repeatable seating.

What is the significance of the WKP25S grade?
The WKP25S grade denotes a coated carbide formulation optimised by Walter Tools for productivity and reliable performance when machining steel and cast iron.
