LNHU090420R-L55T WPP35G milling indexable insert – rectangle, 0° negative rake, Walter Tools

LNHU090420R-L55T WPP35G is a rectangle milling insert designed for efficient steel machining, combining Tiger·tec Gold coating and a specialised chipbreaker for stable cutting performance.

• Tiger·tec Gold coated cutting grade WPP35G
• Rectangle insert with 0° negative rake
• Chipbreaker L55T for improved chip control
• Corner radius 2 for reliable edge strength

Faster, more predictable metal removal with a coated cutting grade

The combination of a Tiger·tec Gold coating and a WPP35G coated carbide base provides enhanced wear resistance and consistent cutting performance when machining steels (ISO P). The coating reduces adhesion and thermal loading at the cutting edge, which extends tool life and reduces the frequency of index changes. By choosing this rectangle insert with a dedicated chipbreaker L55T, shops gain predictable chip formation and fewer interruptions in production, improving throughput on medium- to high-volume runs.

Stable cutting geometry for reproducible surface quality

The insert’s 0° negative rake and corner radius 2 create a stable cutting geometry that tolerates variable feed and depth values without sudden loss of edge integrity. Negative rake geometry increases cutting-edge robustness for interrupted cuts or unstable setups, while the modest corner radius helps to maintain surface finish and dimensional repeatability. These properties make the component suitable for general-purpose steel operations that demand a balance between productivity and consistent part quality.

Practical benefits for workshop efficiency and process security

Using a rectangle insert with a tailored chipbreaker L55T simplifies chip evacuation and reduces rework caused by poor chip control. The insert’s design supports efficient turning of unalloyed and alloyed steels by shaping the chips to exit reliably, lowering the risk of tool or workpiece damage. The result is fewer tool changes, less downtime and an overall improvement in process security—advantages that translate directly into lower per-part machining costs and steadier production cycles.
