SNMG150612-MK5 WKK10S – indexable turning insert, Tiger·tec Silver coating for cast-iron

The SNMG150612-MK5 WKK10S is a square 90° indexable turning insert designed for robust and predictable machining of cast iron components.

• Tiger·tec Silver coating for wear resistance
• WKK10S grade optimised for cast iron
• MK5 chipbreaker for controlled chip formation
• Square 90° form with 1.2 mm corner radius

Precision and productivity for cast-iron workflows

This insert delivers consistent tool life and reduced process variability through a combination of a wear-resistant Tiger·tec Silver coating and the WKK10S cutting grade. The coating lowers friction and improves heat resistance, which is particularly beneficial when machining abrasive cast-iron alloys where rapid flank wear can shorten tool life. By choosing a grade tailored to K-materials, the insert helps maintain dimensional accuracy over longer production runs, reducing unplanned tool changes and increasing overall productivity.

Secure chip formation and stable cutting performance

Equipped with the MK5 chipbreaker and a square 90° geometry, the component promotes predictable chip control, reducing the risk of long or tangled chips in batch operations. The 1.2 mm corner radius supports stable cutting edges and improved strength at the nose, while the 0° negative rake (negative free angle) increases robustness for interrupted cuts and heavy roughing. These design choices combine to enhance process stability and make the insert suitable for demanding finishing and semi-finishing tasks on cast iron.

Adaptability and operational benefits for shops

The insert’s specification—compact 15 mm seat geometry and standardised form—facilitates quick tool changes and compatibility with a wide range of toolholders that accept SNMG-shaped indexable inserts. Using a grade optimised for cast iron means fewer rejects and less rework, translating into measurable cost savings per part. The engineering behind this insert focuses on practical machining outcomes: longer intervals between indexings, consistent surface quality, and reliable cycle times in serial production environments.

Application advice and material suitability

Optimised explicitly for cast iron, this insert is not rated for stainless steels or high-alloy steels in the provided data; it should therefore be specified where Gusseisen is the primary workpiece material. The cutting concept is aimed at managing the short, brittle chips typical of cast-iron machining and at resisting abrasive wear. For specific cutting parameters or to verify compatibility with a particular machine setup, consult technical guidance to align speeds and feeds with workpiece grade and clamping conditions.
