XNMF090612-D27 WKP25S milling insert — Tiger·tec Silver grade for steel and cast iron, Walter Tools

The XNMF090612-D27 WKP25S is a negative‑rake, indexable milling insert from Walter Tools designed for productive machining of steel and cast iron in industrial milling operations.

• Tiger·tec Silver coating for stable cutting
• WKP25S grade for steel and cast iron
• Negative 0° rake for robust engagement
• 1.2 mm corner radius for reliable edge strength

Consistent productivity for steel and cast iron machining

The Tiger·tec Silver series, represented here by the WKP25S grade, is engineered to deliver consistent productivity across a wide range of steels and cast irons. The coated carbide substrate stabilises the cutting edge under the thermal and mechanical loads typical of P and K workpiece groups, reducing unplanned downtime and enabling predictable batch throughput. As a consequence, production planning can rely on fewer insert changes and steadier cycle times, which supports leaner workflows and improved machine utilisation.

Geometry and chip control that reduce process risk

The insert’s negative 0° rake geometry combined with the D27 chipbreaker promotes secure cutting engagement and controlled chip formation when machining tougher steels and abrasive cast irons. The 1.2 mm corner radius increases edge resilience against impact and interruptions, helping to avoid premature edge failure. These geometry choices translate into a dependable cutting process where surface quality and dimensional stability are maintained with less need for corrective rework.

Durable coating and grade for longer tool life

The Tiger·tec Silver coating provides thermal and tribological benefits that slow wear mechanisms and support higher cutting parameters where applicable. The WKP25S grade is optimised for the heat and chip characteristics of steel and cast iron, offering a balance between edge toughness and wear resistance. The result is extended tool life and more consistent component finish, which together lower the overall cost per part and contribute to sustainable machining practices.

FAQ

What materials is this insert suitable for?
The XNMF090612-D27 WKP25S insert from Walter Tools is specified for steel (P) and cast iron (K) applications according to the Tiger·tec Silver grade characteristics.

How does the insert geometry affect machining stability?
The negative 0° rake and 1.2 mm corner radius combine to provide robust engagement and increased edge strength, supporting stable chip formation and reduced risk of edge chipping during interrupted or heavy milling.

Is the D27 chipbreaker suitable for high‑feed operations?
The D27 chipbreaker on this Tiger·tec Silver insert is configured to control chip flow effectively in a range of cutting conditions typical for steel and cast iron machining, improving process reliability over many cutting cycles.

Can this insert be used for finishing passes?
While optimised for productive roughing and general milling of P and K materials, the WKP25S grade and coating can also achieve consistent surface quality in semi‑finishing operations depending on the chosen cutting parameters and machine set‑up.

What benefits does the Tiger·tec Silver coating deliver?
The Tiger·tec Silver coating enhances thermal resistance and reduces friction at the cutting edge, which contributes to longer tool life and steadier performance of the WKP25S inserts under industrial cutting loads.
