SDMW120408-A57 WKP25S milling insert (square 90°, for steel & cast iron) — Walter Tools

A high-performance milling insert, the SDMW120408-A57 WKP25S is designed for efficient roughing and finishing operations in steel and cast iron where predictable wear behaviour and stable chip formation are required.

• Tiger·tec Silver coating for superior wear resistance
• Grade WKP25S for steel and cast iron machining
• Square 90° form with 0.8 mm corner radius
• A57 chipbreaker and 15° clearance angle

Maximise tool life with advanced coated carbide technology

The Tiger·tec Silver coating combined with the WKP25S carbide grade delivers improved resistance to abrasive wear and thermal loading during continuous milling. This technological pairing reduces flank wear rates and extends effective lifetime, which translates into fewer tool changes and lower process interruptions. For mixed-production runs where both long tool life and consistent performance matter, the coated carbide composition supports predictable maintenance intervals and process planning.

Stable chip control and consistent cutting performance

The A57 chipbreaker geometry and the square 90° form ensure reliable chip segmentation when machining both steel and cast iron. A clearance angle of 15° and a corner radius of 0.8 mm balance strength at the cutting edge with favourable cutting forces, reducing vibration and improving cutter stability. These features contribute directly to consistent surface finish and repeatable dimensional results, especially in demanding interrupted cuts and variable stock conditions.

Productivity gains through geometry and grade selection

The combination of the insert’s geometry and the WKP25S grade is oriented towards process security and productivity. The insert supports efficient material removal rates while maintaining edge integrity under typical steel and cast iron cutting regimes according to ISO classifications. For production environments aiming to increase throughput without sacrificing component quality, this insert offers an economical compromise between cutting speed, tool life and surface quality.
