LNMU080404-B57T WPP35G milling indexable insert — Tiger·tec Gold, for steel, by Walter Tools

The LNMU080404-B57T WPP35G is a rectangular milling indexable insert engineered for ISO P applications, offering a coated carbide grade optimised for steel machining with a B57T chipbreaker and a 0.4 mm corner radius.

• Tiger·tec Gold coating for extended life
• Optimised chipformer B57T for stable chips
• Rectangular insert with 0.4 mm corner radius
• Designed for steel machining (ISO P)

Longer service life through advanced coating and grade

The combination of the Tiger·tec Gold coating and the WPP35G grade ensures a marked improvement in wear behaviour while maintaining sufficient toughness for interrupted cuts in steel. Coated carbide provides a protective layer that reduces flank wear and preserves the cutting edge at elevated temperatures, which translates into fewer tool changes and more predictable production cycles. This results in economically efficient machining where longevity and consistent results are priorities.

Predictable chip control and process stability

Equipped with the B57T chipbreaker, the insert supports consistent chip formation when machining steels classified under ISO P, improving evacuation and reducing the risk of built-up edge. The optimised chipformer geometry channels chips away from the cutting zone, aiding surface quality and machine uptime. For automated or long-cycle operations, this leads to enhanced process security and fewer interruptions due to chip accumulation.

Robust geometry for repeatable accuracy

The rectangular geometry with a 0.4 mm corner radius and a negative 0° rake contributes to a strong cutting edge, suitable for moderate to heavy milling tasks where edge strength matters. The insert’s dimensioning and M tolerance class support repeatable clamping and predictable part tolerances. Such geometry offers a pragmatic balance between edge durability and achievable surface finish, making the insert a dependable choice for serial production on a range of steel materials.
