LNMU120608-B57T WKP35S milling insert — Tiger·tec Silver, for steel and cast iron (Walter Tools)

LNMU120608-B57T WKP35S is a rectangular milling insert designed for robust roughing and semi-finishing in steel and cast iron applications, offering a combination of high wear resistance and reliable chip formation

• Tiger·tec Silver coating for long tool life
• Optimised B57T chipbreaker for chip control
• Suitable for steel and cast iron (ISO P/K)
• Rectangular insert with 0.8 mm corner radius

Consistent performance from a modern coating and grade

The combination of the Tiger·tec Silver coating and the WKP35S carbide grade provides a balance of thermal resistance and abrasive wear protection that benefits machining of ISO P (steel) and ISO K (cast iron). The coated hardmetal composition is engineered to stabilise cutting conditions and delay flank wear, which translates into more predictable tool change intervals and steadier production output. This stability supports higher process reliability when machining common steels and grey or ductile cast irons, where chip behaviour and temperature control determine part quality and cycle times.

Geometry and chip control that reduce machining interruptions

A rectangular form with a 0.8 mm corner radius and the dedicated B57T chipbreaker deliver well-controlled chip formation and improved edge strength. The insert’s 0° negative rake increases the cutting edge robustness, making it suitable for tougher engagement conditions and interrupted cuts. These geometry choices reduce the risk of edge chipping and help maintain dimensional consistency, so the machining process is less susceptible to unexpected stops. The M tolerance class ensures repeatable positioning in compatible toolholders, supporting quick indexing and minimal set-up deviation.

Practical integration for production-focused workshops

As part of the Tiger·tec Silver series, this grade is intended to fit into established tool families where predictable wear behaviour and wide material coverage are priorities. The insert’s specification—rectangular format, B57T chipbreaker and WKP35S coating technology—makes it a practical choice for operations aiming to balance tool life with surface finish requirements. With clear material suitability for steel and cast iron, the insert simplifies grade selection for mixed-production environments and reduces the need for frequent trial-and-error when preparing cutting data for batch runs.

FAQ

What materials is this insert designed for?
The LNMU120608-B57T WKP35S insert is specified for ISO P (steel) and ISO K (cast iron), based on the WKP35S grade and Tiger·tec Silver coating.

How does the B57T chipbreaker affect machining?
The B57T chipbreaker promotes controlled chip formation and evacuation, supporting stable cutting and improved surface results when using the Walter Tools insert.

Is the 0° negative relief angle suitable for interrupted cuts?
Yes, the 0° negative relief increases edge strength and helps withstand impacts in interrupted or heavy engagement conditions with this insert.

What benefit does the Tiger·tec Silver coating provide?
Tiger·tec Silver enhances thermal and abrasive wear resistance, which helps extend tool life and maintain consistent performance in the machining of steel and cast iron.

Does the insert require a special toolholder?
The insert fits holders compatible with the LNMU120608-B57T family and M tolerance class; ensure the holder is specified for rectangular inserts with the corresponding chipbreaker geometry.
