SDMT06T204-D51 WKP25S milling insert (square 90°, r0.4) — Walter Tools

A SDMT06T204-D51 WKP25S milling insert engineered for productive machining of steel and cast iron in general milling operations.

• Tiger‑tec Silver coating
• Suitable for steel and cast iron
• Square 90° geometry, r0.4
• Chipbreaker D51 for stable chip control

High productivity through advanced coating and grade

The combination of Tiger‑tec Silver technology and the WKP25S grade provides coated carbide performance tailored to the thermal and abrasive demands of steel and cast iron. This results in improved wear resistance and tool life, which reduces changeover frequency and supports uninterrupted production cycles. The coated surface helps maintain a stable cutting edge under variable loads, contributing to consistent component quality and lower overall machining costs.

Reliable chip control and robust edge geometry

The chipbreaker D51 is designed to produce controllable chips in a wide range of milling conditions, improving evacuation and reducing the risk of built-up edge. The square 90° form combined with an r0.4 corner radius provides a balance between edge strength and surface finish, making the insert suitable for medium finishing and shoulder milling where repeatability matters. The tolerance class M assures dimensional consistency for predictable assembly and easier process planning.

Application guidance and process security for P and K materials

Designed for the ISO groups P (steel) and K (cast iron), this insert is optimised for the chip types and wear behaviour typical of these materials. ISO group designations indicate the intended workpiece families rather than the insert material, so selection should match the specific steel or cast iron grade and the machining strategy. For process security, pair the insert with appropriate cutter bodies and feeds to exploit the grade’s capability for stable cutting and consistent surface quality.

FAQ

Which workpiece materials are recommended for this insert?
The SDMT06T204-D51 WKP25S insert from Walter Tools is recommended for steel (ISO P) and cast iron (ISO K) applications; the WKP25S grade and Tiger‑tec Silver coating are optimised for these material groups.

What does the D51 chipbreaker provide in practice?
Chipbreaker D51 delivers controlled chip formation and improved evacuation, reducing the likelihood of clogging and supporting stable cutting behaviour with consistent surface results when machining steels and cast irons.

How does the r0.4 corner radius influence machining results?
An r0.4 corner radius increases edge robustness and helps achieve a better surface finish in medium finishing passes; it also extends edge life compared with smaller radii under intermittent loads.
