SEHW1204AFN WKP25S – Square milling insert, 20° relief | Walter Tools

A SEHW1204AFN WKP25S milling insert engineered for productive machining of steel and cast iron in general milling applications

• Tiger·tec Silver coating boosts wear resistance
• Optimised for steel and cast iron machining
• Square 90° form for versatile milling
• 20° relief angle for stable cutting

Consistent performance through advanced coating technology

The insert benefits from the Tiger·tec Silver coating and the WKP25S grade, delivering enhanced resistance to abrasive wear and improved edge life. This coated carbide technology is designed to manage the thermal and mechanical loads encountered when machining steel and cast iron, which leads to fewer interruptions for index changes and reduced tooling costs. The coating also promotes stable chip formation, helping to maintain surface quality over longer production runs.

Broad applicability and predictable results for workshop planning

Designed for the ISO groups P and K, the insert is suited to a wide range of workpieces, from unalloyed and alloyed steel to various cast-iron grades. Specified tolerances and the square 90° form give predictable engagement conditions, simplifying process planning and fixture design. For buyers needing reliable cycle-time estimates and reproducible finishes, this geometry supports both roughing and semi-finishing operations with consistent results.

Practical geometry and handling that save time

The 20° relief and a compact plate size with thickness code 04 provide a balance between strength and accessibility in confined toolpaths. The square format provides up to four indexed cutting edges per insert, contributing to economical tool usage and straightforward replacement routines. Technical users will appreciate the stable cutting behaviour and the clear designation of the grade, which together reduce setup variability and support process optimisation.
