WNMG080412-MW5 WKK10S indexable turning insert by Walter Tools — Tiger‑tec Silver, for cast iron

The WNMG080412-MW5 WKK10S is an indexable turning insert designed for productive machining of cast iron, combining a wear‑resistant Tiger‑tec Silver grade with an MW5 chipbreaker and Trigon 80° form for robust, repeatable performance

• Tiger‑tec Silver coating for high wear resistance
• Optimised for cast iron (ISO K) machining
• Trigon 80° form with 1.2 mm corner radius
• MW5 chipbreaker for stable chip control

Extended tool life through advanced coating and grade selection

The Tiger‑tec Silver technology, paired with the WKK10S coated carbide grade, delivers pronounced wear resistance when machining abrasive cast materials. This combination reduces flank and crater wear under cyclic loads typical of grey and nodular cast irons, which in turn prolongs tool life and reduces frequency of indexing. For production environments this means fewer tool changes, more consistent batch output and lower per‑part tooling costs. The coating also supports stable edge geometry during interrupted cuts, improving overall cycle reliability.

Stable cutting geometry for consistent surface quality and uptime

The Trigon 80° insert geometry with a 1.2 mm corner radius and a 0° negative rake provides a mechanically strong cutting edge that resists chipping in interrupted or heavy‑cut conditions. The MW5 chipbreaker is designed to produce short, controllable chips when turning cast iron, preventing entanglement and easing chip evacuation from the cutting zone. Together these features support repeatable surface finish and dimensional stability, helping to reduce rework and machine downtime in medium‑ to high‑volume turning operations.

Seamless integration for productive machining workflows

As a standard WNMG form, this indexable insert fits common clamping systems and can be indexed quickly to restore a fresh cutting edge, keeping set‑up times low. The grade balances wear resistance and toughness for cast‑iron applications, so it is suitable for a range of operations from roughing to semi‑finishing where chip control and edge life are priorities. The result is improved process security and predictable tool performance, which supports lean machining strategies and higher overall throughput.

FAQ

What materials is this insert intended for?
The Walter Tools WNMG080412-MW5 WKK10S is specified for machining cast iron (ISO K) and is optimised for the abrasive and often brittle chip formations typical of these materials.

How does the Tiger‑tec Silver coating benefit production?
The Tiger‑tec Silver coating on the WKK10S grade improves wear resistance and edge stability, which translates to longer tool life and fewer indexings in continuous turning operations.

Which machining tasks suit this insert best?
The Trigon 80° form with a 1.2 mm corner radius and MW5 chipbreaker is suited to stable roughing and semi‑finishing in cast‑iron components where chip control and edge robustness are required.

Is the insert compatible with standard WNMG toolholders?
Yes, the WNMG080412 form is a standard indexable geometry and fits conventional toolholders designed for WNMG inserts, enabling straightforward replacement and indexing.

Can this insert handle interrupted cuts?
The 0° negative rake and robust Trigon geometry provide a strong cutting edge designed to withstand intermittent engagement and reduce chipping during interrupted cuts.
