LNMX070204-F57T WKP35S rectangular milling insert — Tiger·tec Silver, Walter Tools, 0° negative rake, 0.4 mm corner radius

LNMX070204-F57T WKP35S is a rectangular milling insert designed for productive machining of steel and cast iron, combining a coated carbide grade with a chipbreaker optimised for stable cutting.

• Tiger·tec Silver coated carbide grade WKP35S
• Suitable for steel (P) and cast iron (K)
• Rectangular insert with 0.4 mm corner radius
• 0° negative rake angle for stable cutting

Stable cutting and reliable chip control for production work

The Tiger·tec Silver WKP35S grade delivers coated carbide performance geared towards consistent wear resistance and predictable cutting behaviour. The combination of the F57T chipbreaker and the rectangular geometry ensures controlled chip formation when machining common structural steels and cast iron. This results in fewer interruptions for chip clearing, longer uninterrupted cutting times and more consistent surface quality — advantages especially relevant for batch and continuous production environments where process stability is critical.

Robust edge life through grade and geometry

A 0.4 mm corner radius improves edge strength and reduces the risk of premature chipping at interrupted cuts, while the 0° negative rake provides a cutting geometry that favours stability under higher feed rates. These characteristics enable a balance between tool life and productivity: the coated substrate resists abrasive wear typical of cast iron, and the insert geometry supports reliable performance in mixed production runs. The design is therefore well suited for applications requiring repeatable results and low tool-change frequency.

Practical benefits and shop-floor adaptability

The rectangular format and standardized designation simplify inventory and toolholder selection. The insert’s WKP35S coating technology is optimised for the thermal and mechanical demands of steel and cast iron machining, so machinists and process engineers gain a predictable baseline for cutting data development. When integrated into an established tooling system, the insert contributes to reduced setup times and streamlined tool management — measurable process improvements that support efficient workshop operation.

FAQ

What materials is this insert suitable for?
The LNMX070204-F57T WKP35S insert is specified for steel (P) and cast iron (K) applications and is designed to handle the typical thermal and abrasive conditions of these material groups.

How does the 0° negative rake affect cutting performance?
A 0° negative rake improves cutting stability and supports a robust cutting edge, which helps the LNMX070204-F57T WKP35S maintain consistent performance under higher feed rates and more demanding machining conditions.

What benefit does the 0.4 mm corner radius provide?
The 0.4 mm corner radius increases edge strength to resist chipping, particularly at interrupted cuts, enhancing the insert’s service life and contributing to more consistent surface finish during production.

Which chipbreaker is used and why is it important?
The insert features the F57T chipbreaker, optimised for controlled chip formation in steel and cast iron, reducing chip-related interruptions and improving overall machining reliability.
