LNHU160708R-L55T WKP25S rectangular milling insert, Tiger·tec Silver coating, for steel and cast iron (Walter Tools)

LNHU160708R-L55T WKP25S is a rectangular indexable milling insert designed for productive milling operations in steel and cast iron applications

• Tiger·tec Silver coated carbide
• Suitable for steel and cast iron
• Rectangular form, 0.8 mm corner radius
• L55T chipbreaker for controlled chips

Reliable performance for steel and cast iron machining

The Tiger·tec Silver coating combined with the WKP25S grade is engineered to deliver improved wear resistance and thermal stability during continuous milling. This combination mitigates surface degradation at higher cutting temperatures, enabling longer tool life and more predictable results in serial production. Because the grade is optimised for both P (steel) and K (cast iron) groups according to ISO designations, the insert maintains consistent flank and crater wear behaviour when switching between these common engineering materials. The result is a measurable reduction in tool changes and process interruptions, improving throughput without sacrificing component quality.

Geometry and chip control that support productivity

The insert's rectangular form and the L55T chipbreaker generate consistent chip shapes, reducing the risk of entanglement and improving evacuation in both interrupted and continuous cuts. With a corner radius of 0.8 mm, the geometry balances edge strength and surface finish quality, while the 0° negative rake supports stable cutting in tougher engagement conditions. The tolerance class H ensures repeatable fit and seating in standard toolholders, which reduces setup variation and contributes to reproducible machining accuracy. These tangible geometry features translate into fewer reworks and a steadier production rhythm.

Process security and economical machining

Designed for industrial use, the insert promotes process security through stable cutting-edge behaviour and predictable wear progression. The WKP25S grade, part of the Tiger·tec Silver series, is aimed at wide-ranging applications where both abrasion resistance and edge toughness are required, making it suitable for mixed production environments. Using this insert can lower the overall cost per component by extending effective tool life and by reducing unplanned downtime. For production planners, these advantages mean improved scheduling reliability and clearer cost forecasting.

FAQ

What materials is the insert suitable for?
The insert is suitable for steel and cast iron machining; the WKP25S grade and Tiger·tec Silver coating provide balanced wear resistance and toughness for these material groups.

How does the L55T chipbreaker affect machining?
The L55T chipbreaker promotes controlled chip formation and efficient evacuation, which supports consistent surface finish and reduces the risk of chip-related interruptions during milling.

Can this insert be used in heavy-duty interrupted cuts?
With a 0° negative rake and a 0.8 mm corner radius, the insert offers enhanced edge strength and stability suitable for many interrupted cutting scenarios; toolholder and machine rigidity should be assessed for specific heavy-duty applications.
