LNMU160812-F57T WKP25S milling insert by Walter Tools — Tiger·tec Silver, for steel & cast iron

The LNMU160812-F57T WKP25S is a rectangular milling insert engineered for productive machining of steel and cast iron in industrial milling applications.

• Tiger·tec Silver coated grade WKP25S
• Optimised for steel and cast iron machining
• Rectangular 16 size with 1.2 mm corner radius
• 0° negative rake with F57T chipbreaker

Increased process reliability through advanced coating and grade

The combination of the Tiger·tec Silver coating and the WKP25S cemented-carbide grade delivers improved wear resistance and consistent edge life under typical steel and cast iron cutting conditions. The coating technology reduces abrasive and adhesive wear during interrupted cuts, which translates into fewer tool changes and more predictable production cycles. For machining centres where cycle time and repeatability matter, this geometry-grade pairing supports a stable cutting regime and helps maintain component tolerances over longer tool life.

Robust geometry for secure cutting and predictable surface finish

A 0° negative rake geometry with a 1.2 mm corner radius on a rectangular 16 platform offers a balance between edge strength and dimensional control. The negative rake increases the insert's resistance to chipping in interrupted or heavy cuts, while the defined corner radius contributes to reproducible surface quality without compromising edge stability. The F57T chipbreaker is designed to form short, manageable chips when cutting steels and cast irons, reducing the risk of built-up edge and improving swarf handling in high-volume milling operations.

Practical benefits for shop-floor productivity and tool selection

Designed specifically for the machining groups P and K (steel and cast iron), this insert reduces process variability and supports higher material removal rates where appropriate. The coated cemented-carbide construction and the WKP25S grade are tuned for the thermal and mechanical demands of these materials, offering a cost-effective balance of tool life and cutting performance. When selecting cutting parameters, favour stable fixtureings and moderate feeds to exploit the insert's chip control; for specialised applications, consult machining data sheets to match speeds and feeds to workpiece grade.

FAQ

Which materials is this insert intended for?
The LNMU160812-F57T WKP25S is intended primarily for machining steel (P) and cast iron (K) in accordance with ISO material-group guidance.

What benefits does the Tiger·tec Silver grade provide?
The Tiger·tec Silver grade used in WKP25S gives enhanced wear resistance and better thermal stability, which supports longer edge life and predictable performance in steel and cast-iron milling.

How does the F57T chipbreaker affect machining?
The F57T chipbreaker promotes short, controllable chips in roughing and mixed operations on steel and cast iron, improving swarf evacuation and reducing build-up on the cutting edge.

Which geometry features support heavy-duty milling tasks?
Features such as the 0° negative rake, 1.2 mm corner radius and rectangular form provide edge strength and robustness suitable for interrupted cuts and higher radial engagement, aiding process reliability
