DNMG110408-MK5 WKK10S indexable turning insert, Tiger·tec Silver – for cast iron | Walter Tools

A DNMG110408-MK5 WKK10S insert engineered for high-productivity turning of cast iron, featuring a rhombic 55° geometry and a coated-carbide grade tuned to ISO group K materials.

• Tiger·tec Silver coating for wear resistance
• Optimised for abrasive cast iron machining
• Rhombic 55° shape for versatile turning
• 0.8 mm nose radius for defined profiles

Durable coating that extends tool life and reduces downtime

The combination of Tiger·tec Silver technology and a coated-carbide substrate delivers measurable advantages when machining cast iron. The coating is engineered to resist abrasive wear and thermal loading commonly encountered with grey and nodular cast irons, which results in longer insert life and more consistent component quality. By choosing a grade tailored to ISO group K, the insert supports stable performance across a broad range of iron alloys while reducing the frequency of tool changes and process interruptions.

Geometry and chip control for reliable surface finish and productivity

The rhombic 55° geometry, coupled with a 0° (negative) rake and the MK5 chipbreaker, is designed to produce short, controlled chips typical of cast-iron machining. A 0.8 mm nose radius provides a balance between profile definition and tool strength, enabling repeatable surface finishes without compromising tool life. These geometric choices translate directly into process reliability: predictable cutting forces, improved edge stability and consistent dimensional results in repetitive production environments.

Application guidance and integration into production

Specifically developed for ISO group K applications, the insert performs well with abrasive, brittle workpieces that generate short, breaking chips. The DNMG110408-MK5 WKK10S fits standard toolholders compatible with DNMG inserts and is suitable for both roughing and finishing passes when the machining strategy is adjusted to the grade’s strengths. For new process setups, testing with conservative feeds and optimised speeds is advisable to identify the best compromise between surface finish and tool life; Metav Werkzeuge can provide cutting-data suggestions and batch supply to support production ramp-up.

FAQ

Which materials is this insert suitable for?
The DNMG110408-MK5 WKK10S from Walter Tools is optimised for cast iron (ISO group K), designed to handle the abrasive nature and short-chip behaviour of these materials.

What does the Tiger·tec Silver series offer?
Tiger·tec Silver is a coating technology on a coated carbide substrate that enhances wear resistance and thermal stability for extended performance during cast-iron turning with the DNMG110408-MK5 WKK10S.

How does the MK5 chipbreaker affect machining?
The MK5 chipbreaker on this insert promotes short, controllable chips and stable cut evacuation, which improves process safety and consistency when turning cast-iron components.

What is the benefit of the 55° rhombic geometry and 0.8 mm radius?
Rhombic 55° geometry offers versatile approach angles for a range of turning operations, while the 0.8 mm nose radius balances profile accuracy with edge strength for reliable surface quality using the DNMG110408-MK5 WKK10S.
