WNMA080412-RK5 WKK10S indexable turning insert — Trigon 80°, for cast iron (Walter Tools)

The WNMA080412-RK5 WKK10S is an indexable turning insert designed for demanding cast-iron applications, combining a coated-carbide grade with a Trigon 80° form for robust, repeatable cutting.

• Tiger·tec Silver coating for wear resistance
• Optimised for cast iron (ISO group K)
• Trigon 80° geometry for stable cutting
• 1.2 mm corner radius and RK5 chipbreaker

Consistent wear resistance for heavy cast-iron work

The combination of the Tiger·tec Silver coating and the WKK10S grade delivers coated carbide performance tailored to abrasive cast-iron conditions. The applied coating reduces flank and crater wear during interrupted cuts and under variable cutting conditions, extending component life and reducing the frequency of insert changes. For users unfamiliar with coated-carbide technology: the coating forms a protective barrier on the substrate that reduces chemical and mechanical wear, improving lifetime while maintaining acceptable toughness. This results in a more predictable machining process and fewer unscheduled stops for regrinding or replacement.

Geometry and chip control that stabilise the machining process

A Trigon 80° shape with 0° (negative) free angle offers a favourable balance between strength and accessibility in turning operations; the format supports secure clamping and effective cutting-edge support. The RK5 chipbreaker is engineered for short, controlled chips typical of cast-iron materials, which improves evacuation and reduces the risk of chip entanglement. The 1.2 mm corner radius increases edge robustness for roughing passes while still permitting acceptable surface finishes where required. These features together enhance process reliability and help to achieve consistent cycle times on serial production runs.

Practical integration into production workflows

The insert designation WNMA080412-RK5 denotes the standard indexable format and makes the component compatible with a wide range of indexable toolholders, simplifying stocking and tool-change routines. Tolerance class M and the series specification support interchangeability and repeatable positioning in the pocket, minimising setup time. Given the insert’s optimisation for ISO group K, it is particularly suited to foundry work, cylinder blocks, and other cast-iron components where short, brittle chips and abrasive wear are common. For purchasers seeking swift implementation, the robust grade and chipbreaker choice contribute directly to lower tool-related stoppages and steadier output.

FAQ

What materials is this insert optimised for?
The insert is optimised for cast iron machining (ISO group K); the WKK10S grade and Tiger·tec Silver coating address abrasive wear and short-chip behaviour common to these materials.

How does the RK5 chipbreaker affect performance?
The RK5 chipbreaker produces short, controlled chips suited to cast-iron turning, improving chip evacuation and reducing the chance of chip-related interruptions during the cut.

Is the Trigon 80° geometry suitable for heavy-duty turning?
Yes; the Trigon 80° form with a 1.2 mm corner radius and negative geometry provides strong edge support for robust cutting and interrupted operations.

Can the WNMA080412-RK5 be used in standard toolholders?
The WNMA080412-RK5 follows common indexable-insert standards and is compatible with toolholders that accept trigon 80° inserts and the specified insert size.

What benefits does the Tiger·tec Silver series provide?
The Tiger·tec Silver series combines a tailored coating and substrate to improve wear resistance and process stability in abrasive cast-iron applications, helping to extend effective tool life.
