LNHU090408R-L55T WPP35G indexable milling insert — Tiger‑tec Gold, for steel (Walter Tools)

The LNHU090408R-L55T WPP35G is an indexable milling insert designed for robust machining of steels, combining a Tiger‑tec Gold coated grade with an L55T chipbreaker for dependable chip control and long tool life

• Tiger‑tec Gold coating for long tool life
• L55T chipbreaker for reliable chip control
• 0° negative rake for robust cutting action
• Rectangular insert, 0.8 mm corner radius

Consistent edge life and predictable productivity with Tiger‑tec Gold

The coated carbide grade delivers a balanced combination of wear resistance and toughness. With Tiger‑tec Gold and WPP35G, the insert resists abrasive wear while maintaining edge integrity during interrupted or continuous cutting of steels (ISO P). This results in longer tool life and fewer indexings, which supports more stable cycle times and a measurable uplift in process reliability. The formulation is optimised for the typical heat and chip behaviour of steel, reducing unplanned tool changes and improving overall machining throughput.

Controlled chips and cleaner surfaces thanks to the L55T geometry

Chip formation and evacuation are crucial in milling. The L55T chipbreaker is engineered to produce short, predictable chips when machining steels, reducing the risk of re-cutting and keeping the cutting zone clear. Combined with the rectangular shape and a 0.8 mm corner radius, the geometry supports robust entry angles and stable cutting forces. The 0° negative rake increases resistance to edge chipping under heavy cutting conditions, making the insert suitable for applications where durability and process security matter most.

Practical benefits for steel milling operations

Classified for ISO P materials, this insert is intended for a broad range of steel machining tasks from general-purpose roughing to controlled semi-finishing passes. The coated grade WPP35G provides a reliable compromise between resistance to flank wear and enough toughness to withstand intermittent cuts. For operations seeking repeatable component quality and consistent surface finish, the insert helps maintain dimensional accuracy while reducing downtime related to tool wear.

Integration into tool systems and handling advantages

The rectangular format and clearly defined tolerance class (H) allow straightforward seating in compatible cutter bodies designed for these insert dimensions. The plate thickness and geometry support stable clamping and repeatable performance across multiple indexings. As a Walter Tools product from the Tiger‑tec Gold family, this indexable insert is aimed at workshops and production environments that prioritise process security, efficient chip control and predictable replacement intervals.

FAQ

Which materials is this insert intended for?
The insert is specified for steel machining and is classified in the ISO P group; the WPP35G grade and coating are optimised for the heat and chip characteristics of steels.

What benefit does the L55T chipbreaker provide?
The L55T chipbreaker delivers controlled chip formation and short chips in steel cutting, improving evacuation and reducing re-cutting, which aids in surface quality and tool life.

How does the Tiger‑tec Gold coating help in production?
The Tiger‑tec Gold coating increases wear resistance and edge stability, resulting in extended tool life and more consistent performance during medium to heavy steel machining.

What are the key geometric features to consider?
The rectangular shape, 0.8 mm corner radius and 0° negative rake give enhanced robustness at the cutting edge and stable clamping behaviour for demanding milling operations.

Is this insert suitable for roughing or finishing?
The grade and chipbreaker combination makes it versatile for general-purpose milling, offering a compromise between wear resistance for longer runs and enough toughness for interrupted cuts; it is well suited to roughing and semi-finishing in steel.
