LNHU090404R-L55T WKP35G — milling indexable insert, Tiger‑tec Gold grade for steel and cast iron | Walter Tools

The LNHU090404R-L55T WKP35G is a rectangular, negative‑rake milling insert engineered for productive machining of steel (P) and cast iron (K) applications

• Tiger‑tec Gold coated carbide grade WKP35G
• Negative rake 0° for robust cutting
• Rectangular geometry with 0.4 mm corner radius
• Chipbreaker L55T for stable chip control

Reliable cutting performance for steel and cast iron

The combination of the WKP35G grade and Tiger‑tec Gold technology delivers a consistently wear‑resistant cutting edge optimised for the demands of ISO groups P (steel) and K (cast iron). The coated carbide construction improves thermal and abrasive resistance, reducing flank wear and preserving cutting geometry under cyclic loads. In practical terms, this means fewer indexings, predictable tool life and improved process economy when machining unalloyed and alloyed steels or abrasive cast materials.

Geometry designed for strength and predictable results

A negative rake 0° geometry increases edge robustness and reduces the risk of chipping in interrupted cuts; the corner radius 0.4 mm enhances edge stability while maintaining acceptable surface finish. The rectangular shape paired with the chipbreaker L55T controls chip formation and evacuation, which lowers machining interruptions and assists in achieving repeatable component tolerances. These features make the insert suitable for heavier engagement depths and operations where tool reliability is critical.

Practical advantages on the shop floor

The indexable insert fits established cutter bodies and supports rapid index changes for minimal downtime. The Tiger‑tec Gold coating and grade selection translate into improved process security and consistent surface quality, reducing rework and enhancing productivity.
