LNHU080404-B57T WKP35G Fräswendeschneidplatte (milling indexable insert) by Walter Tools

the LNHU080404-B57T WKP35G is a rectangular milling indexable insert designed for medium to heavy-duty milling in steel and cast iron applications

• Tiger·tec Gold coating for extended life
• Optimised for steel and cast iron machining
• 0° negative rake for secure cutting engagement
• Rectangular form with 0.4 mm corner radius

Longer wear life through advanced coating technology

The combination of the Tiger·tec Gold coating and the WKP35G grade delivers a measurable increase in productive cutting time. The advanced coated carbide composition stabilises the cutting edge under thermal stress, which directly reduces flank wear and prolongs service intervals. This means fewer insert changes and more continuous machining, which is particularly beneficial in high-volume production environments where predictable tool life supports planning and cost control.

Reliable chip control and process stability for ferrous materials

Designed for the ISO groups P and K, this insert is optimised for machining steel and cast iron, providing stable chip formation even under typical steel heat loads and abrasive cast-iron conditions. The integrated B57T chipbreaker geometry helps to break and evacuate chips reliably, reducing re-cutting and minimising surface damage. As a result, the cutting process becomes more consistent and reproducible, which supports higher throughput and better surface quality on finished parts.

Geometry that improves cutting security and surface finish

The rectangular form and the 0.4 mm corner radius combine with the 0° (negative) rake to deliver secure cutting engagement and enhanced edge strength. These geometric choices reduce the risk of chipping when interrupted cuts or varying depths of cut occur, and they contribute to a stable cutting force vector. The result is improved surface integrity and fewer rejects, making this insert a practical choice for applications requiring robust performance and repeatability.

Practical selection and application guidance

The insert thickness and form factor suit a broad range of tool holders and milling strategies; the negative rake profile is particularly effective where a strong edge is required or when facing interrupted cuts. The grade WKP35G is balanced for wear resistance and toughness, making it suitable for mixed-production environments. If assistance is needed to determine the optimal cutting data or matching holder, Metav Werkzeuge can provide cutting recommendations and material-specific parameters.

FAQ

What materials is this insert designed for?
The LNHU080404-B57T WKP35G from Walter Tools is designed for machining steel (ISO group P) and cast iron (ISO group K), providing stability under the respective thermal and abrasive conditions.

How does the Tiger·tec Gold coating benefit production?
The Tiger·tec Gold coating on the WKP35G grade improves wear resistance and thermal stability, which extends tool life and supports higher process reliability in continuous milling operations.

What does the 0° negative rake mean in practice?
A 0° (negative) rake increases edge strength and reduces the tendency for chipping during interrupted cuts, making the insert suitable for heavy engagement or unstable cutting conditions.

Which chipbreaker is integrated, and what is its role?
The insert features the B57T chipbreaker, which is engineered to control chip formation and evacuation, reducing re-cutting and helping to maintain consistent surface finish and process security.

Can this insert be used in standard rectangular milling holders?
Yes, the rectangular form and the 4 mm thickness are compatible with common holder types designed for LNHU-style inserts; specific holder selection should match the intended cutting parameters.
