LNHU090404R-L55T WSM35G Rectangular milling insert, Tiger‑tec Gold by Walter Tools

A LNHU090404R-L55T WSM35G milling insert engineered for heavy‑duty machining of stainless steels and heat‑resistant superalloys, featuring a chipbreaker L55T and a compact 0.4 mm corner radius.

• Tiger‑tec Gold coating for high heat resistance
• Suitable for stainless steels and superalloys
• Rectangular form with 0.4 mm corner radius
• 0° negative rake for secure cutting

Consistent performance on demanding materials

The Tiger‑tec Gold WSM35G grade combines a coated carbide substrate with a geometry tuned for stable cutting in demanding conditions. This results in improved edge life when machining tough, work‑hardening materials such as stainless steels and nickel‑based alloys. The insert’s negative 0° rake reduces the tendency for built‑up edge and supports repeatable chip formation, which translates into fewer interruptions and higher process reliability on production runs.

Better chip control and surface integrity

The integrated chipbreaker L55T and the rectangular insert form work together to guide and break chips efficiently, reducing rework and machine downtime. A 0.4 mm corner radius balances edge strength with accessible cutting detail, helping to maintain component surface quality while extending the usable life of the cutting edge. These design choices support a predictable machining window and make tool change intervals easier to plan.

Application scope and mounting considerations

Designed for slotting and shoulder milling operations, the insert fits standard rectangular cutter bodies specified for this ISO designation. The 04 thickness and 09 plate size provide compact support in holders while the H tolerance class ensures consistent seating and repeatable positioning. When paired with a suitable cutter body, the grade performs well under interrupted cuts and in scenarios where thermal stability is critical.

Process benefits and economic rationale

Using a Tiger‑tec Gold WSM35G insert reduces unplanned stoppages through improved wear resistance and predictable flank performance. This leads to higher overall equipment effectiveness and a favourable cost‑per‑component ratio for medium to long production series. The insert’s composition and geometry support higher cutting parameters than uncoated grades in the same class, enabling operators to achieve productive cycle times without sacrificing safety margins.

FAQ

What materials are recommended for this insert?
The LNHU090404R-L55T WSM35G insert is recommended for stainless steels (ISO group M) and heat‑resistant superalloys or titanium (ISO group S), utilising the Tiger‑tec Gold coating to resist heat and preserve edge integrity.

Which chipbreaker is integrated and what is its benefit?
This insert features the L55T chipbreaker, which promotes controlled chip fragmentation and evacuation, reducing the risk of entanglement and improving surface quality during milling.

How does the 0° negative rake affect cutting?
A 0° negative rake increases cutting edge robustness and reduces the formation of built‑up edge when machining sticky or work‑hardening materials, offering more consistent tool life under heavy engagement.
