Maximise process stability and tool life with advanced coating technology

The combination of the Tiger·tec Gold coating and the WKK25G grade delivers measurable advantages in abrasive environments typical for cast-iron machining. The coating reduces flank and crater wear under thermal and mechanical load, which leads to improved tool life and fewer insert changes. For production-oriented shops, the result is a more consistent cycle time and reduced tool-handling overhead. The hardened, coated carbide substrate ensures stable cutting edges even under the short, brittle chips that are characteristic of cast components.

Precision chip control and consistent results for cast-iron operations

The F57 chipbreaker geometry was developed to create short, easily evacuated chips in both interrupted and continuous milling. This insert form supports reliable chip flow and helps to maintain surface quality during roughing and semi-finishing passes. The square 90° shape with a negative 0° relief offers robust edge support, which is beneficial when facing varying cutting conditions or interrupted cuts. As a consequence, process reliability increases and rework is minimised, supporting tighter production schedules.

Practical advantages for production and tool management

Using this indexable insert reduces setup complexity and supports repeatable performance across batches. The insert’s design is suitable for a wide range of cast-iron grades, addressing abrasive wear and frequent chip breakage typical for these materials. Where predictable tool life and consistent results are priorities, the coated grade and geometry contribute to lower overall machining costs through fewer insert changes and stable surface finish. For further clarification on recommended cutting data or toolholder compatibility, Metav Werkzeuge’s consultants can supply tailored guidance based on the specific casting grade and machine tool dynamics.

FAQ

What materials is this insert intended for?
This insert is intended primarily for cast iron machining; the WKK25G grade and Tiger·tec Gold coating are optimised for abrasive wear and short-chip behaviour common to cast materials.

Which chipbreaker does the insert use and what is its benefit?
The insert features the F57 chipbreaker, which produces short, controlled chips to aid evacuation and improve surface quality in both interrupted and continuous milling.

How does the Tiger·tec Gold coating affect performance?
The Tiger·tec Gold coating reduces wear and stabilises the cutting edge under mixed thermal and mechanical loads, resulting in longer tool life and fewer insert changes.
