LNHU080304-B57T WKP35S milling insert — Tiger·tec Silver, for steel and cast iron

LNHU080304-B57T WKP35S is a rectangular indexable milling insert engineered for high‑productivity finishing and semi‑roughing in steel (P) and cast iron (K), combining a coated carbide grade with a dedicated chipbreaker.

• Tiger·tec Silver coating for improved wear resistance
• Optimised for steel and cast iron machining
• Negative 0° rake for robust cutting performance
• 0.4 mm corner radius for reliable edge strength

Consistent wear protection that extends productive cutting time

The Tiger·tec Silver coating applied to this insert enhances thermal stability and reduces abrasive wear when machining ferrous materials. By using a coated carbide grade, the insert maintains a stable cutting edge under elevated temperatures typical of steel and cast iron turning and milling. This results in fewer tool changes and more predictable cycle times, which supports leaner production planning and lower overall machining costs. The coating technology also aids in surface finish stability during longer tool engagements.

Geometry and chip control for reliable production runs

The rectangular format with a negative 0° rake angle and the B57T chipbreaker is designed to favour a robust edge and controlled chip formation, especially where interrupted cuts or variable workpiece conditions occur. The 0.4 mm corner radius increases edge strength, reducing chipping risk and improving tool life in semi‑roughing operations. Together, the geometry and chipbreaker help to maintain consistent material removal rates and reduce vibration, contributing to improved dimensional stability of the workpiece.

Application range and measurable process benefits

Classified for ISO groups P and K, this insert is suited to a broad range of unalloyed and alloyed steels as well as grey and nodular cast irons. The combination of grade and geometry supports higher metal removal rates with reproducible results, which is particularly valuable in batch production and jobbing environments. Process planners can expect improved process security and fewer rejects due to the insert’s predictable wear characteristics and stable cutting behaviour, delivering an efficient balance between performance and economy.

FAQ

What materials is the LNHU080304-B57T WKP35S suitable for?
The LNHU080304-B57T WKP35S is designed for ISO groups P (steel) and K (cast iron), providing reliable performance on unalloyed and alloyed steels as well as typical cast irons.

How does the Tiger·tec Silver coating benefit tool life?
The Tiger·tec Silver coating on the insert reduces abrasive wear and improves thermal resistance, which helps extend the cutting edge life under the heat and stresses encountered when machining steel and cast iron.

What does the negative 0° rake mean for machining?
A negative 0° rake provides a stronger cutting edge and greater robustness against chipping, making the insert well suited to interrupted cuts and tougher workpiece conditions.

Can the insert handle interrupted cutting and tough conditions?
Yes, the rectangular geometry combined with a 0.4 mm corner radius and the B57T chipbreaker gives the insert improved edge strength and chip control, supporting interrupted cuts and variable machining scenarios.

Is this insert compatible with standard rectangular indexable milling holders?
The insert’s rectangular form and designation follow common industry conventions, and it is intended for use in compatible rectangular milling toolholders specified for the LNHU080304 series.
