LNMU160812-B57T WPP35G – Milling insert, Tiger‑tec Gold coated for steel (Walter Tools)

The LNMU160812-B57T WPP35G is a rectangular milling insert designed for reliable steel machining in general milling applications

• Tiger‑tec Gold coated for high productivity
• Optimised B57T chipbreaker for stable chips
• Rectangular geometry with 1.2 mm corner radius
• Negative rake 0° for secure edge performance

Longer tool life through advanced coating and grade selection

The combination of the Tiger‑tec Gold coating and the WPP35G grade delivers measurable improvements in endurance during steel machining. The multi‑layer PVD/CVD coating reduces wear and increases thermal resistance, which translates directly into fewer tool changes and longer intervals between regrinds. For production environments this means a more predictable process and reduced cycle interruptions, supporting higher overall equipment effectiveness.

Stable chip control for consistent surface quality

The B57T chipbreaker, paired with the 0° negative rake, controls chip form and evacuation in typical steel cutting conditions. Stable chips help prevent re‑cutting and reduce the risk of built‑up edge, resulting in a more uniform surface finish and fewer scrap pieces. Clear chip control also reduces downtime associated with manual chip handling and supports safer automated machining.

Robust form and reliable clamping for precise results

With a rectangular form and a 1.2 mm corner radius, this insert balances edge strength with acceptable corner definition. The geometry supports both medium‑to‑heavy cuts and interrupted cutting, where edge robustness prevents premature chipping. The thickness code and insert size provide secure seating in standard toolholders, ensuring repeatable positioning and constant cutting heights across tool assemblies.

Optimised for steel — predictable performance where it matters

Engineered for the P (steel) material group, the insert’s substrate and coating combination is tuned to manage the typical heat generation and chip formation of steel. The result is reliable performance across a broad range of steel grades, from unalloyed to moderately alloyed steels. For manufacturing operations focused on consistent throughput, this configuration offers a strong cost‑to‑performance ratio by extending tool life and stabilising part quality.

FAQ

What material group is this insert intended for?
The LNMU160812-B57T WPP35G is specified for the P material group, meaning it is intended and optimised for machining steel.

How does the Tiger‑tec Gold coating improve performance?
The Tiger‑tec Gold coating on the WPP35G grade increases wear resistance and thermal stability, extending tool life and improving process stability during steel machining.

Is the B57T chipbreaker suitable for heavy cuts?
Yes, the B57T chipbreaker is designed to produce controlled chips under a range of cutting conditions, supporting stable performance even in medium to heavy milling operations.

What does the 0° negative rake mean for cutting behaviour?
A 0° negative rake provides a stronger cutting edge and improved resistance to edge chipping, which is beneficial for interrupted cuts and tougher steel grades.

Can this insert be used in standard rectangular toolholders?
The insert’s rectangular form and size code make it compatible with common toolholders designed for this insert family; secure seating ensures repeatable cutting heights and reliable positioning.
