ADGT1204PER-D51 WKP25S — Walter Tools milling insert, Tiger‑tec Silver, for steel and cast iron, 15° relief

The ADGT1204PER-D51 WKP25S is a coated carbide milling insert designed for productive machining of steel and cast iron, offering a robust chip control geometry for reliable, repeatable results in serial production.

• Tiger‑tec Silver coating for extended tool life
• WKP25S grade optimised for steel and cast iron
• Parallelogram 85° insert with 15° relief
• D51 chipbreaker for consistent chip control

Consistent performance under continuous cutting conditions

The combination of Tiger‑tec Silver coating and the WKP25S grade delivers measurable improvements in wear resistance and process stability. Designed for the thermal and mechanical challenges of machining steel and cast iron, this insert maintains cutting-edge integrity over longer tool life cycles, which reduces downtime and tool changes. The coated carbide substrate supports higher cutting intensities while the surface treatment minimises adhesive and abrasive wear for consistent results.

Geometry that secures accuracy and repeatability

The parallelogram 85° plate form and 15° relief result in an insert that seats securely in the cutter body and provides a predictable cutting angle for stable engagement. The specific shape lowers cutting forces in lateral milling and helps maintain dimensional accuracy across multiple passes. As a result, users benefit from reduced vibration, improved surface quality and fewer rejected parts in batch production.

Reliable chip control for uninterrupted throughput

Equipped with the D51 chipbreaker, the insert shapes and breaks chips efficiently when machining both steel and cast iron. Controlled chip formation reduces the risk of chip entanglement and tool damage, facilitating uninterrupted feed rates and safer handling at the machine. The improved chip flow also contributes to consistent surface finish and less manual intervention between cycles.

Process-oriented grade and coating for diverse applications

The WKP25S grade belongs to a coated carbide family tuned for the ISO groups P and K, which correspond to steel and cast iron. This makes the insert a versatile choice for mixed production shops that require a single, reliable grade across different workpiece materials. The Tiger‑tec Silver technology combines coating adhesion and optimized topography to improve thermal resistance and reduce crater wear during continuous milling.

FAQ

What materials can be machined with this insert?
The ADGT1204PER-D51 WKP25S is suitable for machining steel (ISO group P) and cast iron (ISO group K) thanks to the WKP25S grade and Tiger‑tec Silver coating.

How does the D51 chipbreaker improve productivity?
The D51 chipbreaker on the ADGT1204PER-D51 WKP25S produces short, controlled chips that reduce chip interference and support continuous machining at consistent feed rates.

Is this insert part of a recognised coating series?
Yes, the insert is part of the Tiger‑tec Silver series, which enhances wear resistance and process stability under demanding cutting conditions.

Which cutter holders fit the parallelogram 85° shape?
Cutter bodies that accept ADGT‑style parallelogram inserts with an 85° form and matching size code 12 are compatible with this insert.

What operational benefits does the 15° relief provide?
The 15° relief reduces rubbing and cutting forces in side engagement, improving surface finish and lowering the risk of built-up edge during milling of steel and cast iron.
