LNHU090416R-L55T WPP35G milling insert, Tiger‑tec Gold — Walter Tools

LNHU090416R-L55T WPP35G is a rectangular milling insert designed for efficient steel machining with a negative 0° rake and a robust chipbreaker

• Tiger‑tec Gold coated carbide grade WPP35G
• Optimised chipbreaker L55T for stable chips
• Rectangular insert with 1.6 mm corner radius

Consistent performance for steel machining

The insert is based on the WPP35G grade, a coated carbide developed for machining steels (group P according to ISO 513). The chemical and physical properties of the Tiger‑tec Gold coating improve wear resistance and thermal stability, which translates into longer cutting edge life and fewer tool changes. The result is measurable process stability and predictable reconditioning intervals, making the insert suitable for both high-volume and batch production where repeatability matters.

Secure cutting geometry for demanding operations

A negative 0° rake provides a robust cutting edge and reduces the risk of chipping under heavy or interrupted cuts; combined with the L55T chipbreaker, the geometry promotes compact, controllable chips and steady material evacuation. The rectangular shape and the 1.6 mm corner radius ensure a large contact area and increased rigidity, which supports stable surface finish and dimensional consistency on steel components.

Practical benefits and application guidance

Designed primarily for steel, the grade balance of wear resistance versus toughness makes the insert a versatile option across a wide range of steel alloys. The L55T chipbreaker is especially effective when machining standards that produce short to medium-length chips are required. For optimal results, match the insert to a suitable milling cutter body and follow machine-specific recommendations for speeds and feeds; if additional data is required, Metav Werkzeuge can supply cutting parameter windows and application advice.

Durability and process economy

The combined effect of grade and coating reduces the frequency of index changes and can lower overall tooling costs per component. Improved heat management from the coating and the controlled chip flow from the chipbreaker minimise edge wear and preserve tool geometry, helping to maintain part quality and reduce rework. Where repeatable surface quality and high process uptime are priorities, this insert provides a pragmatic balance between tool life and machining productivity.

FAQ

Which materials is this insert suitable for?
The insert is designed for machining steels (designation P); the WPP35G grade and Tiger‑tec Gold coating are optimised for typical steel heat and chip-formation behaviour.

What advantage does the L55T chipbreaker provide?
The L55T chipbreaker offers controlled chip formation and reliable evacuation, supporting stable cutting and improved surface results when machining steel.

How does the negative 0° rake affect performance?
A negative 0° rake increases edge robustness and resistance to chipping, which is beneficial for interrupted cuts and applications requiring greater cutting edge strength.

Can this insert be used in high-volume production?
Yes; the combination of the WPP35G grade and Tiger‑tec Gold coating is intended to extend edge life and support consistent performance in repetitive production environments.

What is the significance of the 1.6 mm corner radius?
The 1.6 mm corner radius increases contact area and rigidity, contributing to improved dimensional stability and surface finish during milling operations.
