SDMT120408-D51 WKP35G – Milling indexable insert, Tiger‑tec Gold, square 90° (Walter Tools)

The SDMT120408-D51 WKP35G is a square 90° milling insert designed for productive machining of steel and cast iron in serial and batch production environments

• Tiger‑tec Gold coating for long life
• Optimised for steel (P) and cast iron (K)
• Square 90° geometry with 15° relief
• Corner radius 0.8 mm for consistent edge

Higher throughput through tailored grade and coating

The combination of the WKP35G carbide grade with Tiger‑tec Gold coating delivers a balance of wear resistance and fracture toughness that benefits moderate to high cutting speeds. The grade is formulated for the thermal and mechanical loads typical when machining steel and cast iron, which makes it suitable for stable, repeatable runs. The coated surface reduces flank wear and helps maintain a predictable tool life, contributing directly to improved productivity and lower process variability in the workshop.

Geometry engineered for reliability and surface quality

A square 90° insert form with a 15° relief angle and 0.8 mm corner radius provides a strong cutting edge and reliable chip formation. The D51 chipbreaker promotes controlled chip segmentation on both unalloyed and alloyed steels as well as grey and ductile irons, reducing the risk of built-up edge and improving surface finish. These geometry choices support consistent part quality and reduce secondary operations, as edge strength and chip flow are optimised for typical milling conditions.

Practical application and measurable benefits in production

Designed as an indexable milling insert, the item fits standard cutter bodies for flexible tool set‑ups and fast index changes. The combination of grade and chipbreaker enables longer intervals between tool changes and predictable scheduling for replacement, which lowers downtime. The robust design and coating support mixed‑lot production where both steel and cast iron are machined, delivering economic advantages through extended life and steady cutting performance on series parts
