LDMT08T204R-D57 WKP35S indexable milling insert — Tiger·tec Silver, for steel and cast iron — Walter Tools

The LDMT08T204R-D57 WKP35S is an indexable milling insert designed for versatile face and shoulder milling, optimised for efficient material removal from steel and cast iron.

• Tiger·tec Silver coating for longer tool life
• WKP35S grade for steel and cast iron applications
• D57 chipbreaker for improved chip control
• 15° relief angle improves cutting engagement
• Rectangular form with 0.4 mm corner radius

High‑productivity machining and extended tool life

The Tiger·tec Silver coating combined with the WKP35S coated carbide provides a balance of wear resistance and toughness that supports high productivity in mixed production environments. The grade is developed for the thermal and mechanical demands of steel and cast iron, reducing flank wear and maintaining a sharp edge over longer tool paths. This translates directly into fewer indexings, longer tool cycles and more consistent output per insert, helping to lower overall machining cost without sacrificing component quality.

Predictable chip formation and surface quality

Thanks to the D57 chipbreaker geometry and a 15° relief angle, the insert offers controlled chip formation and stable cutting forces during interrupted and continuous cuts. The modest 0.4 mm corner radius assists in producing a reliable surface finish while still permitting robust engagement for heavier passes. The insert is specified for ISO P and K material groups—P for steel and K for cast iron—so the tooling behaviour matches the typical chip shapes and abrasiveness encountered in these materials, reducing burr formation and rework.

Seamless integration into process chains and consistent results

The rectangular plate form and tolerance class M ensure consistent seating and repeatable positioning in standard cutter bodies, supporting reproducible results across batches. With a plate thickness designated T2 and the LDMT geometry, the insert accommodates common clamping systems while delivering good axial and radial stability. The combination of grade and geometry from the Tiger·tec Silver series is aimed at shops that require versatile inserts that perform reliably across a range of steels and cast irons without frequent tool changes.

FAQ

Which materials are recommended for this insert?
The WKP35S grade in the LDMT08T204R‑D57 insert is formulated for steel (ISO P) and cast iron (ISO K) machining, matching the thermal and abrasive demands of both groups.

How does the D57 chipbreaker affect machining?
The D57 chipbreaker promotes controlled chip formation and reliable evacuation, so the insert maintains process stability during both continuous and interrupted cuts.

Is the geometry suitable for heavier cuts and finishing passes?
Yes; the rectangular form with a 0.4 mm corner radius and 15° relief angle delivers the rigidity needed for heavier passes while still allowing acceptable surface quality for finishing when used with appropriate parameters.

What does tolerance class M mean for benching and clamping?
Tolerance class M indicates standard manufacturing tolerances that ensure repeatable seating and positioning in compatible cutter bodies, supporting consistent part-to-part accuracy.
