XDGT2004125R-D57 WKP35S milling insert (for steel & cast iron) – Walter Tools

The XDGT2004125R-D57 WKP35S is a coated carbide milling insert from the Tiger·tec Silver series, engineered for robust performance in roughing and finishing operations on steel and cast iron.

• Tiger·tec Silver coating for extended tool life
• WKP35S grade for reliable chip control
• Suitable for steel and cast iron machining
• 15° relief angle and 1.2 mm corner radius

High-efficiency cutting for steel and cast iron applications

The Tiger·tec Silver coating combined with the WKP35S substrate delivers a balance of wear resistance and toughness suited to ISO group P (steel) and K (cast iron) materials. As a coated carbide insert, the geometry and cutting edge treatment are tailored to manage the heat and chip formation typical of steel machining while resisting the abrasive nature of grey and nodular cast irons. This results in stable cutting conditions, fewer tool changes and more predictable cycle times — clear advantages for batch production and mixed-series manufacturing.

Improved component finish and repeatable tool life

A 15° relief angle and a 1.2 mm corner radius contribute directly to surface integrity and edge strength. The relief angle reduces rubbing on the flank, lowering friction and heat transfer to the workpiece, which helps preserve dimensional accuracy. The corner radius supports a smoother transition between passes and increases edge robustness, reducing the risk of chipping under intermittent or interrupted cuts. Together, these features support consistent surface finish and extend the interval between regrinds or insert changes.

Process reliability that supports productivity and cost control

The insert’s design aims to minimise unplanned downtime through stable chip control and predictable wear behaviour. Reduced edge breakdown and controlled flank wear translate into longer effective tool life and fewer scrap parts. For production environments where cycle time and reproducibility are critical, the combination of coating technology and grade selection helps lower unit machining costs by increasing the net machining time per insert. For tooling engineers, this means fewer routine interventions and a more efficient use of machine hours.

Practical guidance for selection and use

The insert is suitable for a range of milling applications on steels and cast irons as defined by ISO groups P and K. When planning an operation, match cutter geometry, feed and speed to the insert grade and the workpiece condition: the Tiger·tec Silver coating favours moderate to high cutting speeds with good thermal stability, while the WKP35S grade supports reliable chip formation in both continuous and segmented chips. For application-specific optimisation or if any uncertainty exists about compatibility with particular workpiece alloys or cutter bodies, technical advice is available from Metav Werkzeuge to ensure correct selection and setup.
