SNMG090308-MK5 WKK10S square indexable turning insert – Tiger-tec Silver, Walter Tools

The SNMG090308-MK5 WKK10S is a square indexable turning insert developed for productive and reliable machining of cast iron, combining a coated carbide grade with a controlled chipbreaker for stable performance.

• Tiger-tec Silver coated carbide
• Optimised for cast iron ISO K
• MK5 chipbreaker for controlled chips
• 0.8 mm corner radius, square 90° form

Coating and substrate tailored for abrasive cast-iron work

The combination of Tiger-tec Silver and a coated carbide substrate delivers resistance to the abrasive wear typical of cast iron machining (ISO K). The coating reduces flank wear and maintains edge integrity during interrupted cuts, which translates into longer tool life and fewer insert changes. For operations where short, breaking chips and high abrasion occur, this grade provides predictable performance and cost-effective machining cycles.

Geometry that stabilises cutting and chip control

The engineered MK5 chipbreaker and 0° rake (negative) produce reliable chip breaking and secure cutting edge support. The square 90° form with a 0.8 mm corner radius offers a balance between strength and edge definition, enabling both robust roughing passes and fine finishing when required. Controlled chip formation reduces the risk of tool or workpiece damage and simplifies chip evacuation in high-volume turning cells.

Productivity through repeatability and reduced downtime

With a focus on wear resistance and consistent edge geometry, this insert helps maintain cycle times and part tolerances over extended tool life. The WKK10S grade is optimised for the mechanical demands of cast-iron components, which commonly present abrasive particles and fluctuating cutting forces; this results in stable performance and fewer interruptions for regrinding or tool changes. Such consistency supports higher uptime and predictable output in production environments.

Clear application profile and handling guidance

The insert is explicitly specified for cast iron machining (ISO K), making it suitable for foundry components, brake discs and other grey or nodular cast-iron parts where chip breaking and abrasion resistance are priorities. The tolerance class M indicates standard dimensional accuracy for straightforward indexing and interchangeability in compatible toolholders. Select appropriate cutting parameters for coated carbide inserts and ensure correct clamping torque to preserve the insert seat and cutting edge integrity.

FAQ

What materials is this insert suitable for?
The SNMG090308-MK5 WKK10S is specified for machining cast iron (ISO K) and is formulated to cope with the abrasive wear typical of such materials.

How does the MK5 chipbreaker improve machining?
The MK5 chipbreaker on the insert controls chip shape and evacuation, reducing the risk of entanglement and enabling stable cutting in cast-iron turning operations.

What does the 0° (negative) free cutting angle mean for performance?
A 0° rake provides a neutral to negative geometry that strengthens the cutting edge, offering robustness for interrupted cuts and heavy engagement common in cast-iron work.

Is this insert suitable for finishing as well as roughing?
Yes — the square form with a 0.8 mm corner radius delivers sufficient edge strength for roughing while allowing improved surface results when used with appropriate parameters.

How is repeatability ensured when replacing inserts?
Tolerance class M ensures standardised dimensions and simple interchangeability in matching toolholders, supporting consistent positioning and repeatable results with each index.
