ODMT060512-D57 WKK25G milling insert — Walter Tools — Tiger‑tec Gold, 1.2 mm radius

The ODMT060512-D57 WKK25G is a milling indexable insert engineered for productive machining of cast iron, combining a specialised chipbreaker with Walter Tools' Tiger‑tec Gold coating for process stability.

• Tiger‑tec Gold coating for wear resistance
• Optimised chipbreaker D57 for short chips
• 1.2 mm corner radius for stable cutting edge

Increase throughput with a coated grade tuned for cast iron

The combination of a coated cemented carbide grade and a purpose‑designed chipbreaker delivers consistent material removal in abrasive cast‑iron applications. The WKK25G grade, part of the Tiger‑tec Gold family, is formulated to resist abrasive wear while maintaining a stable cutting edge over extended cycles. For production environments the result is fewer tool changes and reduced downtime, which translates into measurable improvements in machining efficiency and predictable process windows.

Secure chip control and surface quality on brittle materials

Short, controlled chips are crucial when machining grey and nodular cast iron to avoid interruptions and protect the workpiece. The D57 chipbreaker is optimised for the typical short, breaking chips of cast‑iron work, enabling reliable evacuation and consistent surface finish. Combined with a 15° front angle and the octagonal insert form, the geometry supports stable engagement and repeatable performance, simplifying toolpath planning and reducing the risk of edge damage during heavy‑duty passes.

Robust edge design for repeatable performance and cost efficiency

A 1.2 mm corner radius and the proven Tiger‑tec coating provide a robust cutting edge that tolerates the abrasive characteristics of cast iron, extending indexable life and lowering unit machining costs. The insert’s tolerance class M and the coded plate thickness and size ensure interchangeability within systemised toolholders, aiding quick replacement and consistent runout behaviour. For contract manufacturers and job shops, this translates into reliable batch throughput and fewer scrap incidents.

Application guidance and process assurance

For challenging components or unfamiliar alloys, application data and trial parameters can make the difference between success and costly rework. Metav Werkzeuge supplies cutting data sheets and can recommend speeds, feeds and depth‑of‑cut settings matched to the WKK25G grade and the specific cast‑iron class. This practical support complements the product’s technical advantages and helps integrate the insert into established machining processes with confidence.

FAQ

What materials is this insert intended for?
The ODMT060512-D57 WKK25G is specified for cast iron; the WKK25G grade is optimised for abrasive, short‑chipping cast‑iron machining.

Which geometry provides chip control with this insert?
Chip control is achieved by the D57 chipbreaker combined with the octagonal plate form and a 15° front angle, delivering short, predictable chips in cast‑iron cuts.

How does the Tiger‑tec Gold coating benefit production?
Tiger‑tec Gold enhances wear resistance and cutting‑edge stability under abrasive conditions, improving tool life and reducing the frequency of index changes.

Is the insert suitable for heavy‑duty roughing?
The robust 1.2 mm corner radius and coated grade offer good resistance to edge breakdown in high‑material‑removal conditions typical of cast‑iron roughing.
