LNHU090412R-L55T WSP45G rectangular milling insert – Walter Tools, Tiger·tec Gold PVD, versatile for steel, stainless and superalloys

LNHU090412R-L55T WSP45G is a rectangular milling insert designed for versatile slotting and face milling applications across a wide range of demanding materials

• Tiger·tec Gold PVD coating
• Suitable for steel, stainless steel, superalloys
• Rectangular form with 1.2 mm corner radius
• 0° negative rake for secure cutting

High-performance grade optimised for demanding materials

The WSP45G grade, produced with Tiger·tec Gold PVD technology, offers a balanced combination of toughness and wear resistance. This makes the insert particularly suitable for interrupted cuts and variable engagement that often occur in milling operations. The coating reduces flank and crater wear, while the base carbide substrate maintains edge robustness; together these properties enable consistently stable chip formation and fewer tool changes, supporting a higher process uptime and predictable cycle times.

Geometry and chip control that support surface quality

A rectangular geometry with a defined corner radius 1.2 mm and the L55T chipbreaker provide controlled chip formation and reliable edge strength during milling. The 0° (negative) rake angle increases cutting-edge stability for heavy or interrupted cutting conditions, reducing the risk of edge failure. These design choices improve surface finish on successive passes, lower the need for finishing operations and contribute to dimensional consistency — essential when tight tolerances and repeatable results are required.

Economic and application-oriented advantages in production

The grade’s application range is identified by the material groups P / M / S, covering unalloyed and alloyed steel, rostfreier Stahl (stainless steel) and heat-resistant superalloys or titanium-based materials. Such breadth reduces the number of tool types needed in mixed-production environments and simplifies tooling logistics. Specified with tolerance class H, the insert supports predictable seating and interchangeability in toolholders. The combination of robust geometry and advanced coating technology leads to fewer interruptions for tool changes and improved overall tool life, which in turn reduces machining cost per component while maintaining high productivity.

FAQ

What materials can be machined with this insert? This insert is suitable for the ISO groups P, M and S; it machines steels, rostfreier Stahl (stainless steel) and heat-resistant superalloys or titanium alloys.

How does the Tiger·tec Gold coating benefit performance? The Tiger·tec Gold PVD coating on the WSP45G grade reduces wear and improves heat resistance, which enhances edge life and process stability in milling operations.

Is the 0° rake angle suitable for heavy milling? Yes; the 0° (negative) rake increases edge robustness for heavy cuts and interrupted machining, providing greater resistance to chipping compared with positive-rake geometries.

Which chipbreaker is fitted and what is its role? The insert features the L55T chipbreaker, which ensures consistent chip control and deflection, supporting improved surface finish and safe chip evacuation under varied cut conditions.

How does the corner radius affect component finish? A corner radius of 1.2 mm helps to strengthen the cutting edge and contributes to improved surface quality on machined faces and shoulders while also aiding in vibration damping during aggressive cuts.
