LNHU080404-F57T WKP35S indexable milling insert, Tiger‑tec Silver, negative 0° rake — Walter Tools

The LNHU080404-F57T WKP35S is an indexable milling insert designed for medium‑ to heavy‑duty milling of steel and cast iron, offering a rectangular shape and a dedicated chipbreaker for controlled material removal.

• Tiger‑tec Silver coating technology
• Grade WKP35S for steel and cast iron
• Rectangular insert, 0.4 mm corner radius
• 0° negative rake for stable cutting

Productivity through engineered cutting performance

This rectangular indexable insert is built around the WKP35S coated cemented carbide grade within the Tiger‑tec Silver series, delivering a balance of wear resistance and fracture toughness. The combination of a dedicated F57T chipbreaker and a 0° negative rake reduces radial and axial vibration, which in turn improves tool life and produces repeatable component quality. For manufacturing environments where cycle time and consistency matter, the engineered geometry enables higher sustained cutting parameters with fewer insert changes, supporting more efficient production flows and predictable maintenance intervals.

Reliable chip control and surface quality for industrial applications

The insert’s chipbreaker and 0.4 mm corner radius support stable chip formation when machining unalloyed and alloyed steel (ISO group P) as well as cast iron (ISO group K). Stable chip control reduces machine downtime from recutting and eases swarf handling, while the coated surface helps to maintain an even cutting edge under thermal load. The net effect is a measurable improvement in surface finish and dimensional stability on the workpiece, which benefits downstream processes such as heat treatment or assembly by reducing rework and inspection overhead.

Practical selection and compatibility in tool systems

As a rectangular, negative‑rake insert with a series‑specific grade, the component fits standard indexable milling toolholders designed for this insert geometry and tolerance. The tolerance class H and the thickness designation 04 ensure repeatable seating in hardened pockets, while the size designation 08 aligns the insert to compatible cutter bodies. When evaluating tool sets, the emphasis should be on matching the insert grade to the material group (P/K) and selecting holder geometries that maintain rigidity to exploit the insert’s wear characteristics and Tiger‑tec Silver coating advantages.

FAQ

What materials is this insert intended for?
The LNHU080404-F57T WKP35S insert is specified for ISO material groups P (steel) and K (cast iron) and is optimised for the typical wear and chip behaviour of those groups.

Does the insert require a special toolholder?
No unique holder is required, but the insert must be used in a milling cutter designed for rectangular, negative‑rake inserts with the appropriate seating for the 04 thickness and 08 size designation.

What is the benefit of the Tiger‑tec Silver technology?
The Tiger‑tec Silver surface treatment on the WKP35S grade improves wear resistance and thermal stability, which translates into extended tool life and consistent cutting performance under higher cutting loads.

How does the 0° negative rake affect cutting?
A 0° negative rake increases edge strength and reduces the likelihood of chipping under interrupted or heavy cuts, providing stable machining conditions for tougher steel and cast iron applications.

Is this insert suitable for finishing operations?
While mainly designed for robust material removal and stability, the combination of chip control and corner radius can produce acceptable surface finishes; selection for finishing should consider feed, speed and toolholder rigidity.
