Durable grade and coating for reliable machining

The combination of the WSP45G grade within the Tiger·tec Gold family and a PVD‑coated carbide substrate provides a robust solution for demanding milling tasks. This formulation is engineered to resist wear and thermal degradation while maintaining a stable cutting edge, which translates into longer effective tool life and fewer changeovers on the shop floor. For metallurgically diverse production runs, the WSP45G grade supports consistent performance across steel, stainless steel and heat‑resistant alloys, reducing the need for frequent grade changes.

Geometry that improves surface finish and repeatability

The insert’s rectangular format with a 0.8 mm corner radius and tolerance class H delivers a reliable cutting geometry that supports consistent part quality. A small corner radius reduces radial cutting forces and helps attain improved surface finish when milling shoulders or light finishing passes, while the negative 0° rake enhances edge strength during interrupted cuts. These design choices result in predictable machining behaviour and make the indexable plate suitable for both roughing and semi‑finishing operations where repeatability is essential.

Optimised chip control for secure production

The integrated L55T chipbreaker is configured to produce manageable chip shapes under a wide range of cutting conditions, lowering the risk of entanglement and promoting continuous material removal. For materials prone to long, stringy chips—such as certain stainless steels and superalloys—this chipbreaker contributes to safer handling and reduced cycle interruptions. The combined effect of chip control and a stable grade supports higher process reliability and fewer unplanned stops, improving overall throughput.

Productivity advantages and application flexibility

As a compact, rectangular milling insert, this component simplifies tooling logistics while enabling adaptable milling strategies across multiple workpiece materials. The insert’s construction supports elevated productivity by extending edge life and allowing aggressive cutting in many cases without sacrificing surface integrity. Paired with suitable toolholders, the plate provides an efficient balance between material removal rate and component quality, making it a practical choice for job shops and production environments that require versatile, dependable inserts.

FAQ

Is this insert suitable for machining stainless steel?
Yes. The LNHU160708R-L55T WSP45G plate is specified for M‑class materials and provides the chip control and heat resistance required for many stainless steel milling applications.

What does Tiger·tec Gold bring to the process?
Tiger·tec Gold is a PVD coating and substrate combination that improves wear resistance, thermal stability and edge strength, helping the insert sustain longer cutting times and consistent performance.

How does the L55T chipbreaker affect machining?
The L55T chipbreaker is designed to produce shorter, controlled chips across a range of cutting conditions, which reduces the likelihood of chip-related interruptions and supports safer, more efficient production cycles.

Can this insert be used for titanium and superalloys?
Yes. The WSP45G grade is intended for versatile use including S‑group materials such as heat‑resistant superalloys and titanium, where edge stability and thermal management are critical.

What is the significance of the negative 0° rake?
A negative 0° rake increases edge robustness for interrupted cuts and heavy engagement, improving resistance to chipping at the expense of slightly higher cutting forces, which is beneficial in demanding milling scenarios.
