LNMU150812-F57T WKP35G milling insert, Tiger‑tec Gold coating, for steel and cast iron — Walter Tools

The LNMU150812-F57T WKP35G is a rectangular milling insert engineered for productive finishing and roughing in steel (P) and cast iron (K) applications, combining a coated carbide grade with a dedicated chipbreaker for consistent chip formation.

• Rectangular insert LNMU150812-F57G WKP35G
• Tiger‑tec Gold coating for high wear resistance
• For steel (P) and cast iron (K) machining
• 1.2 mm corner radius with 0° negative rake

Prolonged tool life through advanced coating technology

The combination of the Tiger‑tec Gold coating and the WKP35G coated‑carbide grade delivers noticeably improved wear resistance and thermal stability during interrupted and continuous cuts. This coating technology reduces flank and crater wear, which translates into fewer tool changes and longer production runs. For operations where consistent component tolerances and reduced tooling costs are priorities, the coated grade offers a measurable advantage by sustaining cutting edge performance under higher temperatures typical of steel machining. The result is greater process reliability and lower overall machining cost per part.

Stable cutting and controlled chips for steel and cast iron

Designed for the ISO groups P (steel) and K (cast iron), the insert’s chip control is driven by the F57T chipbreaker and a 0° negative rake angle, delivering predictable chip breaking and safe evacuation even in tougher materials. A negative rake geometry increases edge robustness and reduces the risk of chipping during interrupted cuts or plunge milling. The outcome is improved surface quality with fewer rejects and a more dependable cycle time, particularly in mixed‑batch production where both steels and grey or nodular cast irons are processed.

Geometry tuned for strength and finishing

The rectangular shape with a 1.2 mm corner radius contributes to a balanced mix of edge strength and surface finish. A larger corner radius increases resistance to radial forces and extends edge life, while still permitting acceptable finishing capabilities on machined faces. The insert’s compact dimensions (designation LNMU150812‑F57T) and plate thickness suited to general milling applications provide stability in the tool holder and support consistent machining results within the stated tolerance class M.

Practical benefits for shopfloor productivity

Adopting this insert supports a streamlined production flow: fewer tool exchanges, reliable chip behaviour, and consistent part quality. The Tiger‑tec Gold series is aimed at shops that value higher tool life and repeatable outcomes across a range of steel and cast‑iron components. If there is any uncertainty about application parameters or cutting data, expert advice is available — Metav Werkzeuge’s technical consultants can assist with cutting speed recommendations and holder compatibility to ensure optimal performance.

FAQ

What materials is this insert suitable for?

The LNMU150812‑F57T WKP35G is designed for steel (P) and cast iron (K) in accordance with ISO 513 groups; the WKP35G grade and Tiger‑tec Gold coating target the thermal and abrasive demands of these materials.

How does the 1.2 mm corner radius affect machining?

A 1.2 mm corner radius increases edge strength and resistance to chipping, improving tool life during heavier cuts while still permitting good surface finish when used with appropriate cutting parameters.

What role does the F57T chipbreaker play?

The F57T chipbreaker is engineered to produce short, controllable chips in typical steel and cast‑iron operations, improving evacu­ation, reducing the risk of re‑cutting chips, and supporting consistent surface quality.

Why choose Tiger‑tec Gold grade WKP35G?

The WKP35G grade within the Tiger‑tec Gold family offers enhanced wear resistance and thermal stability, resulting in longer tool life and more predictable performance in mixed production environments.
