ADMT120408R‑D56 WKK25G Milling indexable insert — Walter Tools, Tiger‑tec Gold, 15°

ADMT120408R‑D56 WKK25G is a Tiger‑tec Gold coated milling indexable insert designed for productive machining of cast iron components, featuring a parallelogram 85° form and a 15° free angle.

• Tiger‑tec Gold coated WKK25G grade
• Optimised for cast iron machining
• Parallelogram 85° form for positive engagement
• 0.8 mm corner radius for reliable edge life

Consistent productivity for abrasive cast iron work

The coated carbide grade WKK25G, developed within the Tiger‑tec Gold family, is specifically tuned for the abrasive wear and the short, breaking chips typical of cast iron (ISO group K). This results in a reduced wear rate on the cutting edge and more predictable tool life, which directly supports higher component throughput and lower tool change frequency. The integrated chipbreaker D56 promotes stable chip formation, improving surface consistency on critical faces and reducing rework.

Geometry and robustness that cut downtime

A parallelogram 85° insert profile combined with a 15° free angle provides positive engagement and reliable cutting geometry in interrupted and full-width passes. The 0.8 mm corner radius balances edge strength and finishing capability: larger radii add robustness, while this value maintains a good compromise between life and surface quality. The insert’s thickness code and inscribed size ensure mechanical stability when mounted in compatible cutter bodies, helping to reduce vibration and extend useful edge life.

Grade and coating explained for process security

The term coated carbide here refers to a hardmetal substrate with a multilayer surface treatment provided by the Tiger‑tec Gold technology: this pairing enhances thermal stability and wear resistance under the high abrasion loads of grey and nodular cast iron. The WKK25G designation denotes the specific Walter Tools grade tuned for such conditions. Selecting this insert for cast iron operations supports reproducible results and improved cost per workpiece through fewer edge failures and consistent cutting performance.
