ODMT050408-D57 WKK25G — Milling indexable insert for cast iron by Walter Tools (Tiger·tec Gold, 15°)

ODMT050408-D57 WKK25G is a coated carbide milling insert designed for efficient machining of cast iron, offering a balance of wear resistance and stable chip formation

• Tiger·tec Gold coating for high wear resistance
• WKK25G grade optimised for cast iron cutting
• Octagonal form with multiple usable edges
• 15° relief angle for controlled cutting geometry

Predictable chip control and surface consistency

The Tiger·tec Gold coating combined with the WKK25G grade provides a wear-resistant cutting edge that is tuned to the abrasive nature of cast iron. Because the grade is engineered for short, brittle chips typical of this material group, chip formation is stabilised and tool life is extended. This leads to a more consistent surface finish and reduced vibration during milling, which benefits repeatable production processes and minimises rework.

Economical edge usage and tool economy

The octagonal plate form and compact dimensions mean multiple cutting edges are available before indexation is required. With a corner radius of 0.8 mm and a robust chipbreaker (D57), the geometry supports productive material removal while maintaining predictable edge wear. In practice, this increases the number of effective cutting edges per insert and lowers cost per component, making the insert suitable for batch production and series machining.

Geometry tuned for stable cutting forces

A 15° relief angle and medium tolerance class ensure the insert provides a reliable cutting geometry that is compatible with a range of toolholders and milling strategies. The moderate relief reduces cutting forces at the edge while preserving strength at the corner, so machining parameters can be set for steady performance rather than conservative idle speeds. This characteristic is particularly advantageous when selecting feeds and speeds for cast-iron operations.

Application guidance and integration in production

The insert is specified under the designation ODMT050408-D57 WKK25G and is supplied in the Tiger·tec Gold series; it is primarily intended for the machining of cast iron where abrasive wear and chip breakage must be controlled. For integration, standard indexable milling toolholders for ODMT-format inserts are used and the plate thickness designation supports stable clamping. Process trials are recommended to determine optimum cutting data for a given machine, workpiece and coolant strategy.

FAQ

How suitable is this insert for grey cast iron versus nodular cast iron?
The ODMT050408-D57 WKK25G insert is optimised for cast iron in general; the WKK25G grade and Tiger·tec Gold coating handle abrasive wear well and offer stable chip formation across grey and nodular cast iron, though cutting data should be adapted to material hardness and chip-break behaviour.

How many cutting edges are available on the octagonal plate?
An octagonal plate form provides multiple usable edges before indexation; the exact number depends on the chosen clamping position, but the geometry is intended to maximise edge economy for series milling operations.

What effect does the 0.8 mm corner radius have on the workpiece finish?
A 0.8 mm corner radius balances edge strength and surface finish: it supports higher feed rates while producing a consistent surface, reducing the tendency for edge chipping during interrupted cuts in cast iron.

Is the insert compatible with standard ODMT toolholders?
Yes, the ODMT050408-D57 format corresponds to standard ODMT-style indexable milling holders; the insert can be mounted and clamped using holders designed for this designation.

What process advantages does the Tiger·tec Gold coating deliver for cast-iron machining?
The Tiger·tec Gold coating increases wear resistance and thermal stability under the abrasive conditions typical of cast-iron machining, which translates into longer tool life and more consistent component quality.
