WCMT080404-RK4 WKK20S — Trigon 80° turning insert for cast iron by Walter Tools

WCMT080404-RK4 WKK20S is a Trigon 80° indexable turning insert engineered for machining cast iron in general turning applications.

• Tiger‑tec Silver coating for increased wear resistance
• Grade WKK20S optimised for cast iron machining
• RK4 chipbreaker for stable chip control
• Trigon 80° form with 0.4 mm corner radius

Enhanced wear protection for abrasive cast‑iron work

The combination of the Tiger‑tec Silver coating with the WKK20S carbide grade delivers a robust solution for the abrasive nature of cast iron. The coating reduces flank wear under interrupted cuts and short, breaking chip regimes typical of grey and nodular castings, which leads to more predictable tool life and reduced production stops. That results in a lower cost per finished component and fewer tool changes, supporting continuous operation in series production.

Geometry and chip control that improve process security

The Trigon 80° insert form and RK4 chipbreaker are matched to produce compact, controlled chips when turning cast iron, improving evacuation in both manual and automated setups. The 0.4 mm corner radius balances edge strength and surface finish, while the 7° clearance angle maintains cutting engagement without excessive rubbing. Together these features ensure stable machining, reproducible results and a reduced scrap rate, which is particularly important when machining complex cast parts or facing variable material batches.

Integration into the workshop for efficient tool management

Specification codes and standard format make the insert straightforward to integrate into existing tool holders and inventory systems. The standard WCMT080404-RK4 designation simplifies reordering and ensures compatibility with many established clamping systems. Using a dedicated grade optimised for cast iron helps planners and buyers forecast tool consumption more precisely and supports leaner stock levels. The result is improved shop-floor uptime and easier process planning across shift patterns.

FAQ

Is this insert suitable for cast iron machining?
Yes. The WCMT080404-RK4 WKK20S from Walter Tools is specifically graded (WKK20S) and coated (Tiger‑tec Silver) for machining cast iron and handling its abrasive wear characteristics.

What benefits does the Tiger‑tec Silver coating provide?
The Tiger‑tec Silver coating on the WCMT080404-RK4 WKK20S improves wear resistance and reduces flank wear, extending tool life in interrupted cuts and abrasive cast‑iron conditions.

How does the RK4 chipbreaker affect machining?
The RK4 chipbreaker is designed to form compact chips and improve evacuation when turning cast iron, contributing to process security and a consistent surface finish with the Trigon 80° geometry.

What does the 0.4 mm corner radius mean for my parts?
A 0.4 mm corner radius offers a compromise between edge durability and surface quality; with the WCMT080404-RK4 WKK20S it supports stronger edges while maintaining acceptable finish on cast‑iron components.

Can the insert be used in standard toolholders?
The WCMT080404-RK4 code follows common insert standards and is compatible with many standard turning insert clamping systems; check holder specifications to confirm fit.
