SNMG120408-MK5 WKK10S – indexable turning insert for cast iron, Tiger·tec Silver by Walter Tools

The SNMG120408-MK5 WKK10S is an indexable turning insert designed for robust machining of abrasive cast‑iron materials, combining a coated carbide grade with a chipforming geometry for controlled, repeatable cutting.

• Tiger·tec Silver coated grade WKK10S
• Optimised for cast iron machining
• MK5 chipbreaker for secure chip control
• Square 90° form with 0.8 mm corner radius

Longer tool life through a wear‑resistant grade

The Tiger·tec Silver WKK10S grade is a coated carbide formulation developed for abrasive environments typical of cast iron (ISO K). The coating and substrate combination increase resistance to flank and crater wear, which translates into longer intervals between index changes and fewer unplanned tool‑life stops. For production facilities focused on predictable cycle times, this means a measurable reduction in tool change frequency and improved process stability under repetitive loads.

Predictable chip control and robust cutting performance

Equipped with the MK5 chipbreaker and a square 90° geometry, this insert provides consistent chip control for breaking the short, brittle chips produced by cast iron. The 0° negative rake further enhances edge strength, allowing secure engagement during interrupted cuts and heavier depths of cut. The 0.8 mm corner radius supports robustness at the cutting edge, reducing the risk of micro‑chipping and helping to maintain surface quality with fewer tool index positions consumed.

Streamlined integration for higher productivity

As an indexable turning insert, the component can be fitted to standard turning holders, enabling quick replacement and minimised downtime. The combination of a proven coated grade and reliable chipbreaker supports continuous machining with repeatable results, contributing to overall productivity gains on the shop floor. By favouring stable chip formation and long tool life, the insert supports efficient resource allocation and a lower cost per finished component without sacrificing process reliability.

Practical application guidance for cast‑iron operations

This product is primarily intended for machining cast iron in accordance with the ISO K grouping; it is especially suitable where abrasive wear and short, breaking chips are expected. For operations requiring different material coverage or for optimised cutting data, consult application engineers to align cutting speeds and feeds with machine and workpiece constraints. The insert’s design balances wear resistance and toughness to deliver consistent performance across roughing and medium‑depth finishing passes in cast‑iron production.

FAQ

What materials is this insert suitable for?
The SNMG120408-MK5 WKK10S insert is optimised for cast iron (ISO K) applications and is formulated to manage the abrasive wear and short, breaking chips typical of such materials.

How does the MK5 chipbreaker improve machining?
The MK5 chipbreaker on this Walter insert promotes consistent chip segmentation and evacuation, which reduces the risk of entanglement and supports steady surface finish during continuous production.

What does the designation SNMG120408-MK5 mean?
The designation describes a square insert with a 90° geometry, 12 mm size and 4 mm thickness, fitted with the MK5 chipbreaker; the WKK10S suffix denotes the Tiger·tec Silver coated grade for cast iron.

Is the insert suitable for interrupted cuts?
Yes. The combination of a negative 0° rake, a 0.8 mm corner radius and a robust coated grade makes the insert resilient under interrupted cutting conditions commonly encountered in cast‑iron turning.
