CNMA120404-RK5 WKK10S – Indexable turning insert, Tiger·tec Silver, RK5 – Walter Tools

The CNMA120404-RK5 WKK10S is an indexable turning insert engineered for efficient machining of cast iron, featuring a Tiger·tec Silver coated grade and an RK5 chipbreaker for controlled, repeatable cutting.

• Tiger·tec Silver coated grade WKK10S
• Optimised RK5 chipbreaker for cast iron
• Rhombic 80° form with 0.4 mm corner radius
• Negative 0° rake for stable cutting

Reliable chip control and longer tool life for cast-iron work

The combination of the RK5 chipbreaker and the Tiger·tec Silver coating reduces abrasive wear typical when machining cast iron (ISO K), leading to more stable cutting and fewer insert changes. The coating is a modern, multi-layered treatment on coated carbide that improves thermal and abrasive resistance; this means less flank wear during long cycles and a more predictable maintenance interval. For production environments where repeatability and uptime matter, this geometry-and-grade pairing translates into measurable process gains and lower total operating costs.

Geometry that delivers consistent surface finishes and repeatability

The rhombic 80° plate form with a 0.4 mm corner radius and a negative 0° relief angle creates a robust cutting edge that resists chipping under interrupted cuts. The compact plate size and standardised tolerance class M ensure consistent seating and repeatable clamping across toolholders, which benefits batch production and tool reprofiling. Because the insert geometry prioritises edge strength, it supports conservative feeds for improved surface quality while maintaining productivity in medium-duty turning operations.

Designed for process reliability and straightforward integration

Manufactured to the Tiger·tec Silver series and graded as WKK10S, this insert is optimised specifically for abrasive, short-breaking chips encountered in grey and nodular cast irons. The combination of a tailored chipbreaker and the coated carbide substrate simplifies machining strategy: predictable chip flow reduces downtime from clogged tooling, and the grade’s wear characteristics support stable tool life across varying cast-iron compositions. Walter Tools’ engineering focus on stable cutting margins and consistent results aids process planning and reduces cycle variability.

FAQ

What materials is this insert intended for?
The CNMA120404-RK5 WKK10S is designed primarily for cast iron (ISO K) machining and its grade and chipbreaker are tuned to handle abrasive, short-breaking chips typical of these materials.

How does the RK5 chipbreaker affect cutting performance?
The RK5 chipbreaker promotes controlled chip formation and evacuation; this reduces the risk of built-up edge and improves process stability when using the WKK10S grade on cast-iron components.

What benefits does the Tiger·tec Silver coating provide?
Tiger·tec Silver offers enhanced abrasion and thermal resistance on the coated carbide substrate, increasing wear life and supporting consistent results across longer cycles with the CNMA120404-RK5.

Is the insert geometry suitable for interrupted cuts?
Yes; the rhombic 80° form combined with a negative 0° relief and a 0.4 mm corner radius gives the insert the edge strength required for many interrupted and semi-finish turning applications.
