LNMU080404-F57T WKP35S indexable milling insert, Tiger·tec Silver for steel and cast iron — Walter Tools

The LNMU080404-F57T WKP35S is a rectangular indexable milling insert engineered for reliable, high‑productivity milling in steel (P) and cast iron (K) applications.

• Tiger·tec Silver coating for extended tool life
• WKP35S grade for stable chip formation
• Rectangular geometry with 0.4 mm corner radius
• Suitable for steel and cast iron machining

Consistent chip control for efficient, high‑productivity milling

The combination of the WKP35S coated‑carbide grade and the F57T chipbreaker delivers consistent chip control and reduced machining downtime. The Tiger·tec Silver coating improves abrasive wear resistance, which helps maintain cutting edge stability during extended cuts. This results in more predictable tool life and a steadier surface finish, making the insert particularly well suited to continuous production runs where process repeatability and economic machining are priorities.

Versatile application across steel and cast iron with secure geometry

Designed for the ISO material groups P (steel) and K (cast iron), the insert’s geometry balances robustness and precision. The rectangular shape and the 0° negative clearance angle provide secure seating in the cutter body and resistance to shock loads common in interrupted cuts. For workshops processing a mix of unalloyed, alloyed steels and cast components, this geometry reduces the need for frequent tool changes while supporting reliable metal removal rates and consistent component quality.

Precision edge form and tolerance for process security

A corner radius of 0.4 mm and tolerance class M contribute to reproducible cutting performance and predictable workpiece tolerances. The controlled edge radius supports stable chip formation at moderate feeds, while the M tolerance ensures interchangeability of inserts during serial production. Backed by Walter Tools’ focus on stable cutting edges and reliable tool life, the insert supports cost‑conscious machining strategies without sacrificing surface quality or dimensional repeatability.

FAQ

Which materials is this insert intended for?
The LNMU080404-F57T WKP35S is specified for machining steel (P) and cast iron (K) according to ISO material groups.

What benefit does the F57T chipbreaker provide?
The F57T chipbreaker supports controlled chip formation and evacuation, improving surface quality and enabling longer, uninterrupted cuts with the WKP35S grade.

How does the 0.4 mm corner radius affect the machining result?
A 0.4 mm corner radius offers a balance between edge strength and surface finish, reducing the risk of edge chipping while producing an acceptable surface at moderate feeds.

Is the insert suitable for interrupted cuts and heavy engagement?
The rectangular geometry and 0° negative clearance angle enhance seat stability and resistance to shock, which is advantageous in interrupted milling operations.

What does tolerance class M imply for series production?
Tolerance class M indicates consistent dimensional accuracy and repeatability, simplifying insert replacement and maintaining process stability across production batches.
