WNMA080404-RK5 WKK10S — Trigon 80° turning insert for cast iron, Tiger·tec Silver (Walter Tools)

The WNMA080404-RK5 WKK10S is a Trigon 80° turning insert designed for high-productivity machining of cast iron components in industrial turning applications.

• Tiger·tec Silver coating technology
• For cast iron machining (K)
• Trigon 80° insert form
• 0.4 mm corner radius, negative 0° rake

Increased productivity for abrasive cast iron work

The WNMA080404-RK5 WKK10S turning insert combines a coated carbide substrate with the Tiger·tec Silver coating system to deliver extended tool life under the abrasive conditions typical of cast iron. The grade WKK10S is tuned for brittle, breaking-chip behaviour and high wear resistance, which reduces insert changes and downtime. For process engineers, the outcome is a measurable productivity gain: more uninterrupted cutting time and fewer interruptions for tool exchange, contributing to a smoother production flow.

Reliable geometry and controlled chip formation

The Trigon 80° form and the RK5 chipbreaker produce consistent, short, predictable chips when machining cast iron, improving safety at the tool–workpiece interface and easing chip evacuation. The 0.4 mm corner radius balances edge strength and dimensional control, while the negative 0° relief establishes stable cutting forces in heavy or interrupted cuts. Explained simply: the chipbreaker shape directs fragmenting chips away from the cutting zone, reducing the risk of surface damage and allowing higher feed rates with preserved surface quality.

Suitability and handling in production environments

Designed specifically for cast iron (material group K), the insert’s specifications—size designation 08 and thickness 04—match common toolholder systems used in high-volume turning. The coated carbide construction provides an economical compromise between wear life and cost per cutting edge, making the grade suitable for series production as well as demanding maintenance and repair operations. Compatibility with standard turning toolholders and established clamping systems simplifies integration into existing toolsets, enabling predictable cycle times and repeatable component accuracy.

FAQ

What materials is this insert intended for?
The WNMA080404-RK5 WKK10S turning insert (Walter Tools) is optimised for cast iron machining and listed for material group K.

What does the RK5 chipbreaker deliver in practice?
RK5 provides controlled, short chip formation under typical cast iron cutting conditions, improving chip evacuation and surface integrity when using the WNMA080404-RK5 WKK10S insert.

Is the insert compatible with standard toolholders?
The Trigon 80° form and size designations (08 / 04) conform to common indexable insert tooling systems, enabling straightforward installation into standard turning toolholders.

How does the Tiger·tec Silver technology benefit production?
Tiger·tec Silver coating on the WKK10S grade increases wear resistance and promotes stable edge life during abrasive cast iron operations, which supports longer cutting intervals and consistent part quality.

Can this insert handle interrupted cuts or heavy roughing?
Yes, the negative 0° relief and the 0.4 mm corner radius give the insert robust edge strength for interrupted cuts and heavier roughing passes in cast iron.
