ODMW050408-A57 WKK25G milling indexable insert — Tiger·tec Gold for cast iron (Walter Tools)

A robust ODMW050408-A57 WKK25G milling insert designed for stable, high‑productivity machining of cast iron components in industrial milling operations

• Tiger·tec Gold coating for extended tool life
• Optimised for abrasive cast iron machining
• 15° free angle for stable cutting geometry
• Octagonal form enables multiple indexings

Maximise productivity and consistency in cast iron milling

The combination of the Tiger·tec Gold technology and the WKK25G grade delivers a high level of wear resistance tailored to abrasive cast iron conditions. The coated carbide substrate is engineered to withstand the typical short, breaking chips of grey and nodular cast irons, which reduces flank wear and extends the interval between edge changes. This results in measurable productivity gains and fewer unscheduled tool swaps during batch production, supporting steady cycle times and predictable output.

Stable cutting geometry for improved surface quality

A 15° free angle together with a 0.8 mm corner radius preserves edge strength while providing a controlled engagement with the workpiece. The moderate corner radius helps to balance edge robustness with achievable surface finish, making the insert suitable where consistent part tolerances and repeatable finishes are required. The A57 chipbreaker is formed to control chip fragmentation in discontinuous cast iron cutting, improving evacuation and reducing the risk of built-up edge.

Economical indexing and process security

The octagonal geometry increases the number of usable cutting edges per insert, lowering cost per cutting edge and reducing tooling consumption over time. With a tolerance class of M, this insert supports reproducible clamping and stable seating in indexable holders, which contributes to process reliability and predictable tool life. The design emphasises efficiency for medium‑to‑high production runs where tool change downtime must be minimised.

Application scope and industrial benefits

Specifically developed for the machining of cast iron (ISO group K), this insert suits shoulder milling, ramping and interrupted cuts commonly encountered in automotive, pump and valve component production. The WKK25G grade combines good wear properties with universality across cast iron types, enabling flexible use in mixed production environments. For workshops aiming to improve throughput while maintaining surface integrity, this insert offers a pragmatic balance of performance and cost effectiveness.
