SDMT1204AZN-D57 WKK25G – Indexable milling insert, Tiger·tec Gold, square 12 mm (Walter Tools)

The SDMT1204AZN-D57 WKK25G is a square indexable milling insert optimised for cast-iron applications; its Tiger·tec Gold coating and D57 chipbreaker support stable chip formation and consistent edge life.

• Tiger·tec Gold grade WKK25G
• Optimised for cast-iron machining
• 15° relief angle for secure cutting
• Square 90° format, 12 mm size

Consistent edge life through coated carbide technology

The combination of the WKK25G coated carbide grade and the Tiger·tec Gold series targets the abrasive wear typical of cast-iron machining. This results in stable chip formation and extended tool life, which reduces downtime for tool changes and increases productive cutting hours. The cutting-material pairing is designed for short, breakable chips common in cast materials, translating into predictable performance and repeatable results in series production.

Geometry and dimensions that simplify set-up and precision work

The square 90° insert geometry and the 15° relief angle provide a balanced compromise between strength and chip evacuation. The insert size of 12 mm with a thickness corresponding to code 04 ensures rigid clamping and resistance to edge deformation during heavy cuts. These geometric features reduce set-up iterations and help maintain consistent tolerances across batches, supporting efficient process control on milling heads and indexable-cutter systems.

Practical chip control and production-oriented features

The D57 chipbreaker is engineered for controlled chip splitting and evacuation in cast-iron operations, lowering the risk of built-up edge and machine interruptions. The insert is supplied in tolerance class M, enabling reliable seating and repeatability in toolholders. Designed to integrate into industrial milling workflows, this grade offers a cost-effective balance between wear resistance and cutting reliability for medium to high-volume production runs.
