WNMG060408-MK5 WKK10S indexable turning insert — Trigon 80°, for cast iron, Walter Tools

The WNMG060408-MK5 WKK10S is a trigon indexable insert engineered for productive turning of cast iron components, combining a coated carbide grade with an MK5 chipbreaker for controlled, repeatable machining.

• Tiger·tec Silver coating for extended life
• Optimised for cast iron machining
• Trigon 80° geometry for high edge stability

Reliable chip control that reduces downtime

The combination of the MK5 chipbreaker and the WKK10S grade, built on Tiger·tec Silver technology, delivers consistently broken chips when machining cast iron. The cutting geometry was engineered to address the short, brittle chips typical of grey and nodular cast irons; as a result, chip evacuation is improved and tool-related interruptions are reduced. The insert’s coated carbide composition increases abrasion resistance, which translates into longer edge life under the intermittent, abrasive conditions common in cast-iron turning.

Stable cutting edge for demanding operations

With a Trigon 80° shape and a 0.8 mm corner radius, the insert offers a robust edge that resists chipping during heavy cuts or interrupted cuts. The negative 0° relief provides a strong cutting face and supports higher radial forces, making the insert suitable for applications requiring durability rather than aggressive shearing. Tolerance class M ensures repeatable seating in standard WNMG toolholders, which supports process consistency and simplifies tool management in production settings.

Efficiency gains through material and coating synergy

The Tiger·tec Silver coating, combined with the WKK10S substrate, focuses on reducing abrasive wear from cast-iron alloys. This pairing results in predictable tool wear behaviour and permits longer tool-change intervals in many applications. For workshops aiming to improve productivity and reduce per-part tooling costs, the improved wear resistance enables higher uptime and steadier component quality without complex coolant strategies.

Practical integration into turning processes

The insert conforms to the WNMG form factor and a compact 06 size with plate thickness 04, enabling straightforward replacement in compatible toolholders. Its MK5 chipbreaker is optimised for chip control on cast iron (ISO group K), so tool-path programmes and feed rates that worked with other WNMG inserts can often be retained with minimal adjustment. If uncertainty remains about compatibility with a specific holder or machining scenario, technical consultation is available to assist with cutting data and clamping recommendations.

FAQ

What materials is this insert designed for?
The WNMG060408-MK5 WKK10S is designed primarily for machining cast iron (ISO group K), with the grade and chipbreaker tuned for the abrasive and brittle chips typical of these materials.

How does the Tiger·tec Silver coating improve performance?
The Tiger·tec Silver coating on the WKK10S grade increases abrasion resistance and stabilises wear rates, which helps extend cutting edge life and maintain consistent surface finish during cast-iron turning.

What benefits does the Trigon 80° shape provide?
The Trigon 80° geometry offers a strong cutting edge and improved stability under higher radial loads, reducing the risk of chipping in interrupted cuts and supporting robust turning operations.

Is the MK5 chipbreaker suitable for finishing passes?
The MK5 chipbreaker is optimised for chip control in cast-iron machining; depending on feed and depth of cut, it can be used for both medium and certain finishing passes where controlled chips and surface quality are required.
