VNMG160412-MK5 WKK20S – Indexable turning insert, Tiger-tec Silver (Walter Tools)

The VNMG160412-MK5 WKK20S is an indexable turning insert designed for productive machining of cast iron components, featuring a rhombic 35° shape and a chipbreaker optimised for broken chips.

Tiger-tec Silver coating for wear resistance
Optimised for cast iron (ISO group K)
Chipbreaker MK5 for stable chip formation
Rhombus 35° geometry with 1.2 mm corner radius

High productivity for cast‑iron turning operations

The Tiger‑tec Silver grade WKK20S is developed for abrasive wear typical of cast‑iron machining and delivers predictable tool life under demanding conditions. Its coated carbide substrate provides a balance between toughness and wear resistance that reduces downtime from frequent index changes. The rhombic 35° geometry and chipbreaker MK5 combine to produce short, controllable chips, which helps maintain cycle times and reduces manual chip management in the machining cell.

Durable edge condition and reliable surface results

Thanks to the negative 0° rake and defined corner radius 1.2 mm, the insert sustains a robust cutting edge that resists notch wear and edge chipping during interrupted cuts. This results in consistent surface integrity of workpieces and lowers the risk of scrap. The insert’s execution and tolerance class are matched to industrial turning applications, making it suitable for repetitive production where dimensional stability and repeatability matter.

Practical integration and benefits for the workshop

The VNMG form enables flexible turning strategies, from finishing to medium‑depth roughing when using the correct cutting parameters for cast iron. With its series characteristics and material focus on ISO group K, the insert supports a wide range of grey and nodular castings. Machinists gain from simpler process setup and fewer tool changes, which contributes to improved throughput and a leaner tool inventory.

FAQ

What workpiece materials is this insert designed for?
The VNMG160412-MK5 WKK20S insert is designed primarily for cast iron applications (ISO group K), with the WKK20S grade optimised for abrasive wear and short, breaking chips.

How does the Tiger‑tec Silver series improve performance?
The Tiger‑tec Silver series on the VNMG160412-MK5 offers enhanced wear resistance and edge stability, which leads to longer tool life and more consistent results during cast‑iron turning with the chipbreaker MK5.

What chip control can be expected with the MK5 chipbreaker?
The MK5 chipbreaker on this insert promotes short, controlled chips suited to interrupted and continuous turning of cast iron, improving process reliability and machine cleanliness.

Is the corner radius suitable for finishing operations?
The 1.2 mm corner radius provides a compromise between strength and surface finish; it is suitable for many finishing and medium‑depth turning tasks on cast iron components.

Can this insert be used in automated production environments?
Yes, the VNMG160412-MK5 WKK20S is engineered for reproducible performance in serial production, supporting stable tool life and reduced index changes under appropriate cutting conditions.
