TCMT110204-RK4 WKK20S – Indexable insert for turning and boring, Tiger‑tec Silver, cast iron (Walter Tools)

The TCMT110204-RK4 WKK20S is a triangular indexable insert engineered for reliable machining of cast iron, combining a coated carbide grade with a specialised RK4 chipbreaker for stable, short-chip formation in interrupted and continuous cuts

• Tiger‑tec Silver coating for long tool life
• Optimised RK4 chipbreaker for cast‑iron chips
• 7° clearance angle, 0.4 mm nose radius

Durable coating and grade for extended tool life

The insert uses the Tiger‑tec Silver coating together with the WKK20S carbide grade to deliver enhanced wear resistance when machining abrasive cast‑iron materials. This combination reduces flank wear and maintains cutting-edge integrity over longer cycles, translating into fewer indexings and lower tooling cost per part. For users seeking reproducible production runs, the coated grade offers a predictable service life and consistent performance under the typical thermal and mechanical loads encountered in cast‑iron turning.

Stable chip control and secure cutting geometry

Equipped with an RK4 chipbreaker and a triangular 60° form, the insert is optimised for producing short, controllable chips in grey and nodular cast irons. The 0.4 mm nose radius and 7° clearance angle contribute to a balanced mix of strength and edge definition, improving surface finish and dimensional stability. The result is reduced risk of built‑up edge, improved process security and a lower incidence of unexpected rework in series production.

Efficient use and straightforward tool management

The three‑sided triangular design provides multiple cutting edges per insert, simplifying inventory and reducing overall tooling expenditure. The insert’s designation aligns with standard toolholders and ISO classifications, enabling quick implementation into existing turning or boring setups. Backed by the Walter Tools engineering concept, the solution supports productive machining strategies with minimal setup time and clear upgrade paths for different cast‑iron applications.
