LNMU090404R-L55T WKP35G rectangular milling indexable insert — Tiger‑tec Gold, for steel and cast iron — Walter Tools

LNMU090404R-L55T WKP35G is a rectangular milling indexable insert engineered for productive roughing and medium finishing of steels and cast iron in industrial machining.

• Tiger‑tec Gold coating for long tool life
• WKP35G coated carbide grade
• Rectangular insert with 0.4 mm corner radius
• Optimised L55T chipbreaker for steels and cast iron

Engineered for productive machining and predictable outcomes

The Tiger‑tec Gold series provides a coated carbide design that improves wear resistance and thermal stability, enabling higher cutting speeds and longer tool life. With the WKP35G grade, the insert is optimised for the thermal and mechanical demands of machining steel and cast iron, delivering more stable chip formation and fewer tool changes. This focus on process efficiency reduces downtime and contributes directly to lower total machining costs, while the L55T chipbreaker supports consistent chip control in interrupted and continuous cuts.

Stable cutting performance and surface quality in mixed production

A rectangular insert with a 0° negative rake and a 0.4 mm corner radius combines robustness with good edge strength, making it suitable for operations where reliability matters. The geometry minimises chipping in tougher passes and helps maintain dimensional stability over longer tool life. As a result, workshops experience more predictable batch outputs and improved surface finishes, particularly when switching between unalloyed or alloyed steels and abrasive cast irons. The insert’s tolerance class M supports repeatable seating in toolholders, aiding consistent fixture-to-fixture performance.

Simple integration and application-focused advantages

The insert’s designation and chipbreaker geometry support straightforward selection for industrial tool groups and make integration into existing machining families uncomplicated. The coated substrate resists abrasive wear typical of cast iron and the heat exposure from steel machining, which decreases the frequency of regrinds and replacements. For production planners, this translates into predictable maintenance intervals and easier cost forecasting. Technical datasheets and cutting parameters are available for adaptation to specific machines and operations to ensure the best balance of productivity and tool life.

FAQ

What materials is this insert designed for?
The LNMU090404R-L55T WKP35G insert from Walter Tools is designed for machining steel (P) and cast iron (K) according to the ISO material groups specified for the Tiger‑tec Gold grade.

How does the Tiger‑tec Gold coating benefit production?
Tiger‑tec Gold coating on the WKP35G grade increases wear resistance and thermal stability, allowing higher cutting speeds and longer edge life, which improves productivity and reduces tool-change frequency.

What cutting tasks suit the rectangular shape and 0.4 mm corner radius?
The rectangular geometry with a 0.4 mm corner radius is ideal for robust roughing and medium finishing operations where edge strength and repeatability in seating are required.

Is the chip formation controlled for interrupted cuts?
Yes, the L55T chipbreaker is optimised for stable chip control in both continuous and interrupted cutting conditions commonly encountered when machining steels and cast iron.
