WNMG060412-MK5 WKK10S — Turning indexable insert, Tiger·tec Silver, for cast iron — Walter Tools

The WNMG060412-MK5 WKK10S is a Trigon 80° turning insert with an MK5 chipbreaker, engineered for high-performance finishing and semi-finishing of cast iron components.

• Tiger·tec Silver coating for high wear resistance
• Optimised MK5 chipbreaker for short chips
• Trigon 80° form with 1.2 mm corner radius
• Grade WKK10S tuned for cast iron machining

High wear resistance for consistent cycle times

The combination of the Tiger·tec Silver coating and the WKK10S grade provides a wear-resistant surface optimised for the abrasive nature of cast iron. This coated cemented carbide formulation is designed to withstand the micro-abrasive attack and the frequent short, breaking chips typical of grey and nodular cast irons. The result is improved tool life and stable machining performance, which reduces setup variance and supports predictable production planning. The coating technology also aids heat resistance, helping to keep flank wear progression gradual under standard cutting conditions.

Geometry and chip control that boost productivity

The Trigon 80° insert form and the MK5 chipbreaker act together to produce controlled, short chips and a reliable cutting action in interrupted and continuous cuts. A 1.2 mm corner radius offers a balance between edge strength and surface quality, while the 0° (negative) relief angle increases robustness on heavy cuts and where form accuracy is critical. These geometry choices lower the risk of edge chipping and enable higher radial engagement, so cycle times can be shortened without compromising finish. For machinists, this translates into fewer tool changes and more consistent component tolerances.

Practical compatibility and process reliability on cast iron

With tolerance class M and codes indicating size and thickness, the insert integrates easily into standard turning toolholders that accept WNMG-style plates. The MK5 chipbreaker and the dedicated WKK10S grade make this insert particularly suitable for cast iron according to ISO 513 designations, providing stable chip formation and repeatable surface results. For production teams, that means less scrap, fewer reworks and a dependable contribution to output quality. The insert’s design supports both roughing strategies that demand edge security and finishing passes that require good surface integrity.

FAQ

What materials is this insert designed for?
The WNMG060412-MK5 WKK10S is designed primarily for cast iron applications (material group K according to ISO designations).

How does the MK5 chipbreaker affect chip formation?
The MK5 chipbreaker produces short, controllable chips, which improves process safety and eases chip evacuation during turning with the WNMG060412-MK5 WKK10S.

Is the insert suitable for heavy cuts?
Yes. The 0° negative relief and Trigon 80° geometry increase edge robustness, making the insert suitable for higher radial engagement and interrupted cuts.

What benefits does Tiger·tec Silver provide?
The Tiger·tec Silver coating enhances wear resistance and heat tolerance, extending service life of the WKK10S grade in abrasive cast iron machining.

Which tolerance class applies and why is it important?
Tolerance class M ensures dimensional consistency for repeatable tool clamping and accurate positioning in compatible toolholders.
