XNHF090612-D27 WKK25G milling insert — Tiger·tec Gold for cast iron (Walter Tools)

The XNHF090612-D27 WKK25G is a coated carbide milling insert optimised for efficient and consistent machining of cast iron components.

• Tiger·tec Gold coating technology
• Grade WKK25G for cast iron
• 0° negative relief for stable cutting
• 1.2 mm corner radius for edge strength

Consistent chip control for abrasive cast iron

The Tiger·tec Gold WKK25G grade has been developed for the specific demands of cast iron machining, where abrasive wear and short, brittle chips are common. The coating and substrate combination provides high wear resistance and predictable wear behaviour, which reduces unplanned tool changes. By stabilising chip formation with the D27 chipbreaker geometry, the insert enables steady removal rates and comparable cycle times, so process planners can rely on consistent part tolerances in serial production.

Strong cutting edge for fewer interruptions

A 1.2 mm corner radius and a 0° negative relief geometry combine to produce a robust cutting edge that resists chipping under intermittent loads. This mechanical stability means fewer tool interventions and a lower risk of scrap from edge failure. The reinforced edge geometry is especially beneficial for interrupted cuts and short overhangs, providing improved service life while maintaining dimensional accuracy during longer shifts.

Predictable surface finish and process security

The coated substrate and precise geometry of the insert support a uniform surface quality even in demanding materials. With the coating process optimised for adhesion and thermal stability, the insert achieves consistent results across batches, promoting process reliability. For planners and machine operators, this translates into reduced measurement rework and more predictable downstream operations, enhancing overall manufacturing throughput.

Easy integration into existing holders and workflows

The insert designation and geometry (XNHF090612-D27, chipbreaker D27, size 09, thickness 06) match common Walter Tools milling systems, enabling straightforward replacement and minimal setup adjustments. Designed for the ISO group K (cast iron), the grade simplifies tool selection in mixed-material shops. If application-specific data are required, Metav Werkzeuge can provide further recommendations and compatibility checks to ensure optimal cutting parameters and fixture arrangements.
