WNMG080408-MK5 WKK10S — indexable turning insert, Trigon 80°, for cast iron (Walter Tools)

A WNMG080408-MK5 WKK10S indexable insert engineered for productive cast iron turning, combining a robust trigon geometry with a coated carbide grade for stable wear behaviour.

• Tiger·tec Silver coating for wear resistance
• Optimised MK5 chipbreaker for reliable chip control
• Trigon 80° geometry for secure seat and rigidity
• 0.8 mm corner radius for mixed roughing and finishing

Proven coating and grade for high process reliability

The insert uses the Tiger·tec Silver coating technology applied to a coated carbide substrate, designed specifically for abrasive cast iron operations. This combination improves resistance to abrasive wear and helps maintain a stable cutting edge over extended cycles. The supplied grade, WKK10S, is tuned for the demands of cast iron (ISO group K), offering a balance between wear resistance and toughness that reduces unexpected tool failure. As a result, production runs can be longer and more predictable, supporting higher overall equipment effectiveness.

Geometry and chip control that support consistent surface quality

The Trigon 80° shape together with the MK5 chipbreaker delivers robust clamping engagement and controlled chip formation when turning cast iron. The 0.8 mm corner radius contributes to a firm cutting edge capable of withstanding interrupted cuts while still allowing good surface finish in mixed operations. The insert’s 0° rake (negative) setting improves edge strength for heavy cuts, while the plate thickness and form provide dimensional stability — all of which minimise chatter and help achieve repeatable part tolerances during serial production.

Applications, handling and process advice for the shop floor

This insert is suited primarily for turning cast iron materials in production environments where process security and predictable tool life are key. The chipbreaker geometry helps break the typically short, brittle chips of cast materials and supports automatic chip evacuation. For set-up, ensure correct seat and clamping in the toolholder specified for trigon inserts, verify rake orientation (negative 0°), and adopt cutting parameters aligned with the workpiece grade. For additional machining data or to match the insert to specific toolholders, Metav Werkzeuge’s technical team can supply tailored recommendations.

FAQ

Which materials is this insert suitable for?
The WNMG080408-MK5 WKK10S insert is specified for cast iron machining (ISO group K) and its grade and coating are optimised for the abrasive, short-chip behaviour typical of these materials.

What are the key geometry details to consider?
The insert has a Trigon 80° form, a 0.8 mm corner radius and a 0° negative rake angle; these features support secure clamping, edge strength and consistent chip formation in turning operations.

How does the MK5 chipbreaker affect chip control?
The MK5 chipbreaker is designed to produce controlled short chips when machining cast iron, aiding automatic evacuation and reducing the risk of entanglement at the cutting zone.

Is this insert coated and what benefit does the coating provide?
Yes — the insert uses Tiger·tec Silver coating on a coated carbide base, which improves abrasive wear resistance and contributes to longer, more reproducible tool life under cast iron conditions.

Can this insert be used for finishing operations?
The 0.8 mm corner radius supports mixed roughing and medium-finishing; for very fine finishing, smaller radii are typically preferred. The insert provides a good compromise between edge robustness and surface quality.
