LNMU201012-F57T WKP35S milling indexable insert by Walter Tools — Tiger‑tec Silver, rectangular geometry

LNMU201012-F57T WKP35S is a rectangular milling indexable insert designed for productive machining of steel and cast iron with the Tiger‑tec Silver coating system

• Tiger‑tec Silver coating for extended life
• WKP35S grade tuned for steel and cast iron
• Rectangle form with 1.2 mm corner radius
• Chipbreaker F57T for controlled chip formation

Longer tool life and consistent edge performance from advanced coating

The combination of the Tiger‑tec Silver coating and the WKP35S carbide grade delivers predictable wear behaviour under typical steel and cast‑iron cutting conditions. Coating technology reduces flank wear and maintains the cutting edge temperature within acceptable limits, which translates into longer usable life of the insert and fewer indexings. For process planning, this means improved tool‑life forecasts and fewer unscheduled tool changes, supporting a steady production flow and reduced machine downtime.

Reliable chip control and surface quality for demanding operations

The integrated chipbreaker F57T is engineered to shape chips reliably during roughing and semi‑finishing passes in both steel and cast iron workloads. Controlled chip formation reduces the risk of built‑up edge and improves surface finish consistency, lowering the need for secondary operations. The negative rake geometry of 0° enhances cutting stability when interrupted cuts or heavy engagement are encountered, providing more predictable machining performance in batch and single‑part production alike.

Geometry and tolerance for process stability and repeatability

Rectangular form and a 1.2 mm corner radius ensure a balance between strength and accessibility in corner profiles. The insert thickness of 10 mm and tolerance class M contribute to secure clamping and repeatable positioning in standard indexable cutter bodies. Such geometric consistency supports higher spindle speeds and feed rates without compromising the cutting edge life, making the insert suitable for shops prioritising productivity and reproducible component quality.

Practical applicability and material scope

Classified for ISO groups P (steel) and K (cast iron), this insert is intended for a broad spectrum of ferrous materials encountered in general machining. Its material compatibility and coated substrate make it appropriate for applications where abrasive wear and variable chip breakage behaviour are expected. The insert’s design supports both conventional and climb milling strategies in face and peripheral milling operations when paired with suitable cutters.
