LNHU090408R-L55T WKP35G – Milling indexable insert, Tiger·tec Gold coating (for steel & cast iron) by Walter Tools

The LNHU090408R-L55T WKP35G is a negative‑relief rectangular milling insert designed for high‑productivity face and slot milling in steel and cast iron.

• Tiger·tec Gold coating for high wear resistance
• WKP35G grade optimised for steel and cast iron
• 0° negative relief for secure edge engagement
• 0.8 mm corner radius for robust cutting edge

Increased process reliability from advanced coating technology

The Tiger·tec Gold coating and the WKP35G cemented‑carbide grade are engineered to extend tool life under continuous machining of unalloyed and alloyed steel and abrasive cast iron. The coating reduces flank wear and thermal softening at the cutting edge, which translates into fewer indexings and longer effective cutting times. For operations where consistent surface quality and predictable tool change intervals matter, this combination contributes directly to higher net productivity and lower process variance.

Secure cutting engagement and predictable chip control

A 0° negative relief geometry improves edge stability during interrupted cuts and heavy depth‑of‑cut entries. The rectangular plate form, paired with the chipbreaker L55T, promotes controlled fragmentation of swarf in both long‑ and short‑chip conditions typical for P and K material groups. The result is reduced risk of built‑up edge and improved evacuation of chips from pocketed or through‑slot operations, which supports reliable cycle times and fewer machine interruptions.

Robust edge design for repeatable performance

The 0.8 mm corner radius and the insert’s construction prioritise edge strength, making the plate suitable for heavier engagement and general milling tasks where edge chipping must be avoided. This geometry gives a balance between strength and achievable surface finish: a larger radius increases edge resilience, while the coating maintains wear resistance. For shops standardising on versatile inserts, this option reduces the need for frequent grade changes across similar steel and cast‑iron components.

Practical advantages for workshop integration

The insert is supplied in a proven rectangular format and a standard thickness/size code that fits common milling bodies, allowing straightforward integration into existing tool holders. Its negative geometry is particularly beneficial for robust clamping systems and milling heads where secure seating is essential. The overall design aims to simplify inventory: one insert grade covers a broad material range and a variety of general‑purpose milling operations, lowering tooling complexity without sacrificing performance.

FAQ

What materials is this insert suitable for?
This insert is designed for machining steel (P) and cast iron (K); the WKP35G grade is optimised for those material groups.

How does the Tiger·tec Gold coating improve tool life?
The Tiger·tec Gold coating reduces abrasive and thermal wear on the cutting edge, so the insert maintains cutting performance for longer under typical steel and cast‑iron conditions.

Why choose a 0° negative relief geometry?
A 0° negative relief increases edge stability and secure clamping, which is advantageous for interrupted cuts and heavy engagement common in milling operations.

Is the corner radius suitable for finishing operations?
The 0.8 mm corner radius prioritises edge strength; while it supports good surface quality in general milling, finer finishing may require a smaller radius depending on tolerances.

Can the chipbreaker handle both long and short chips?
The L55T chipbreaker is developed for controlled chip formation across varying cutting conditions, improving evacuation in both long‑chip and short‑chip scenarios.
