LNMU080404-B57T WKP35S milling insert — Tiger·tec Silver coated carbide for steel and cast iron | Walter Tools

LNMU080404-B57T WKP35S is a rectangular indexable milling insert designed for productive machining of steel (P) and cast iron (K), combining Tiger·tec Silver coating and a B57T chipbreaker for controlled machining performance.

• Tiger·tec Silver coating for long tool life
• Optimised B57T chipbreaker for reliable chips
• Designed for steel (P) and cast iron (K)
• Negative geometry with 0° clearance angle

Consistent edge life through advanced coating and grade

The combination of the WKP35S grade and Tiger·tec Silver coating provides elevated resistance to abrasive and thermal wear, which translates into longer intervals between index changes. As a coated carbide solution for industrial milling, this insert is engineered to maintain a stable cutting edge, helping to reduce scrap rates and secure process stability. The coating technology supports higher cutting speeds while preserving the substrate, offering a clear efficiency advantage in repetitive production runs.

Improved chip control and surface quality with the B57T breaker

Equipped with the B57T chipbreaker and a negative geometry featuring a 0° clearance angle, the insert promotes short, controlled chips that are easier to evacuate from the cut—a decisive benefit when machining cast parts or interrupted cuts. The modest corner radius of 0.4 mm contributes to reliable edge strength and consistent surface finish; the rectangular plate form and the U geometry aid in indexable positioning and tool life predictability. These design choices reduce the need for frequent process adjustments and support reproducible component quality.

Application focus and productivity advantages

Designed primarily for steel (P) and cast iron (K) in accordance with ISO classifications, the insert suits a range of roughing and semi-finishing tasks when combined with the appropriate cutter body and cutting parameters. The negative rake and robust grade make it particularly effective where abrasion from cast materials or moderate built-up edge tendencies of steels would otherwise limit performance. Choosing this insert can contribute to lower total machining costs through extended edge life and fewer tool changes, enhancing overall shop-floor productivity and throughput.
