SDMT09T308-D57 WKP25S indexable milling insert — Tiger·tec Silver, 15° clearance, Walter Tools

The SDMT09T308-D57 WKP25S is an indexable milling insert designed for general-purpose and finishing operations in steel and cast iron, offering a balanced geometry and a dedicated chipbreaking system for predictable machining results

• Tiger·tec Silver coating technology
• WKP25S coated carbide grade
• 15° clearance angle for general milling
• Suitable for steel and cast iron applications

High-performance grade for mixed-material milling

The combination of Tiger·tec Silver coating and the WKP25S coated carbide delivers a reliable balance between wear resistance and edge strength, tailored for the thermal and abrasive conditions encountered when machining steel and cast iron. The 15° clearance contributes to stable tool engagement and reduced rubbing, while the 0.8 mm corner radius supports a good surface finish without excessive cutting forces. This insert is intended where consistent tool life and predictable regrind intervals are priorities, enabling a smoother manufacturing flow and fewer unscheduled tool changes.

Predictable chip control and edge stability for uninterrupted production

Equipped with the D57 chipbreaker, the insert promotes short, manageable chips that clear reliably from the cutting zone, reducing the risk of recutting and improving process stability. The chipbreaker geometry is optimised for both continuous and interrupted cuts, resulting in stable chip formation and productive machining across a range of feeds and depths. For applications where repeatable part quality and uptime are essential, the chip control design helps maintain dimensional consistency and reduces secondary operations.

Geometry and tolerance for repeatable results on the shop floor

The square 90° form and defined features such as tolerance class M, plate T3 thickness and size 09 ensure straightforward indexing and predictable seating in standard toolholders. The square shape allows multiple cutting edges per insert, improving economy per edge, while the defined tolerance supports consistent clamping and minimal runout. These geometrical and tolerance choices contribute directly to repeatable performance and a reliable surface finish in series production.

Easy integration and brand-backed reliability

As an indexable insert from Walter Tools, the design emphasises practical integration into existing milling systems, offering compatibility with common clamping concepts and replacement schedules. The coated carbide construction and chipbreaker choice make the component suitable for both catalogue-referenced and geometry-dependent applications in mixed-material environments. For procurement and process planning, the insert represents a technically clear, economical option to raise the stability of daily machining tasks.
