LNHU160708R-L55T WKP35G milling insert — Tiger·tec Gold, rectangular, Walter Tools

The LNHU160708R-L55T WKP35G is a rectangular milling insert engineered for productive machining of steel and cast iron in serial and job-shop environments, combining a modern coated carbide grade with a controlled chipbreaker for repeatable results

• Tiger·tec Gold coating for extended tool life
• WKP35G grade optimised for steel and cast iron
• 0° negative relief for secure cutting engagement
• 0.8 mm corner radius for consistent edge strength

Greater productivity through optimised grade and coating

The combination of Tiger·tec Gold and the WKP35G grade focuses on high productivity and predictable wear behaviour when machining ISO group P (steel) and K (cast iron) materials. The coating system reduces flank wear and increases resistance to abrasive attack, while the substrate maintains toughness under typical milling loads. The integrated L55T chipbreaker improves chip separation and lowers heat concentration at the cutting edge, which results in longer intervals between indexings and fewer unplanned tool changes. For production planners this translates directly into improved machine uptime and lower per-part tooling cost.

Stable cutting geometry for repeatable results

A 0° negative relief geometry provides a stable cutting face ideal for interrupted cuts or applications with variable engagement. The 0.8 mm corner radius increases edge strength and reduces susceptibility to chipping under heavy feed, making the insert suitable for medium to heavy roughing passes. The rectangular form offers multiple effective cutting edges per index, and the plate thickness designation supports axial and radial rigidity in common milling holders. These geometric choices aim to deliver consistent surface quality and predictable tool life in everyday shop-floor conditions.

Practical machining behaviour and process recommendations

The insert is specified for machining steel and cast iron; the chipbreaker design helps produce short to segmented chips typical of these materials, reducing the risk of entanglement and improving evacuation. When using the insert, select cutting data that balances feed per tooth and cutting speed for the workpiece grade—prioritise stable clamping and appropriate coolant strategy where applicable. The controlled combination of grade and chipformer reduces thermal load at the cutting edge, enabling higher metal removal rates without sacrificing component tolerances. Operators will appreciate the straightforward performance characteristics during set-up and process validation.

Reliability and workshop-level advantages

Workshops seeking a balance of process security and cost-effectiveness gain from the repeatable performance of the Tiger·tec Gold family and the WKP35G grade. The insert supports predictable wear mechanisms, eases tool management, and aligns with modern manufacturing demands for throughput and consistent part quality. The Walter Tools pedigree behind this product underpins expectations of stable edge preparation and reliable batch-to-batch consistency, making it a pragmatic choice for operations focused on uptime and reproducibility.

FAQ

What materials is this insert designed for?
The LNHU160708R-L55T WKP35G insert is designed primarily for ISO material groups P (steel) and K (cast iron), with the WKP35G grade and Tiger·tec Gold treatment optimised for these workpiece types.

How does the L55T chipbreaker affect machining?
The L55T chipbreaker provides controlled chip formation for short to segmented chips typical of steel and cast iron, improving chip evacuation and reducing heat concentration at the cutting edge.

Why is a 0° negative relief useful in milling?
A 0° negative relief increases contact stability at the cutting edge, making the insert less sensitive to interruption and fluctuation in engagement and thus enhancing process security.

What advantages does the Tiger·tec Gold series provide?
The Tiger·tec Gold series offers an advanced coating-substrate combination that improves wear resistance and edge stability, resulting in longer tool life and consistent performance during production.

Can the insert be used for finishing and roughing operations?
Yes; the 0.8 mm corner radius and robust chipformer make the insert suitable for medium to heavy roughing while still providing adequate control for certain semi-finish applications when the process is parameterised accordingly.
