DNMG110412-MW5 WKK10S indexable turning insert — robust chip control and Tiger·tec Silver coating by Walter Tools

DNMG110412-MW5 WKK10S is an indexable turning insert designed for efficient machining of cast iron components, offering high wear resistance and stable cutting performance in demanding production environments

• Tiger·tec Silver coating technology
• Optimised chipbreaker MW5
• Rhombic 55° geometry, 1.2 mm radius
• Negative rake 0° for heavy cuts

Higher productivity through specialised coating and chip control

The combination of the Tiger·tec Silver coating with the tailored WKK10S grade delivers a clear productivity advantage when machining abrasive cast iron. The coated cemented carbide substrate is engineered to resist the rapid abrasive wear typical of grey and nodular cast irons, which reduces flank wear and extends edge life. With a dedicated chipbreaker MW5, the insert produces short, controllable chips that lower the risk of built-up edge and improve cycle stability. The result is fewer tool changes, reduced downtime and a measurable improvement in process efficiency for repetitive turning operations.

Consistent accuracy and surface quality from a stable geometry

The rhombic 55° form and 1.2 mm corner radius create a dependable cutting geometry that balances cutting forces and edge strength. This geometry supports stable contact conditions at the cutting edge, which helps maintain dimensional accuracy and repeatable surface finish over longer tool life. The insert’s negative 0° relief makes it suitable for heavier cutting depths and interrupted cuts, where a robust edge is essential. For shops seeking predictable results in series production, this indexable solution offers both positional stability and reliable wear behaviour, simplifying tool planning and inventory management.

Practical application notes and holder compatibility

Designed specifically for machining cast iron (ISO group K), the insert performs best in toolholders that provide rigid clamping and correct rake orientation for negative-relief inserts. The DNMG110412-MW5 WKK10S works well in both finishing and medium-roughing passes when cut parameters are adapted to material grade and machine rigidity. For cast iron, prioritise moderate cutting speeds with sufficient feed to maintain chip breakage as dictated by the MW5 geometry; this approach balances thermal load and mechanical wear. If required, Metav Werkzeuge can provide recommended cutting data and holder options to match machine capacity and component requirements.

FAQ

Is this insert suitable for all cast iron types?
The DNMG110412-MW5 WKK10S is specified for ISO group K materials and is optimised for the abrasive wear and short, breaking chips typical of many cast irons; select cutting data according to the specific cast iron grade.

What advantages does the Tiger·tec Silver coating provide?
The Tiger·tec Silver coating on the DNMG110412-MW5 WKK10S enhances wear resistance and thermal stability, which extends edge life and supports consistent productivity in cast-iron turning.

Can the insert be used for interrupted cuts or roughing?
Yes; the negative 0° relief and robust geometry of the DNMG110412-MW5 WKK10S make it well suited to interrupted cuts and heavier roughing passes, provided the toolholder and machine offer sufficient rigidity.

Which chipbreaker should be selected for fine finishing?
The MW5 chipbreaker integrated in this insert is tuned for controllable, short chips in cast iron; for very fine finishing, adjust feed and speed to achieve the desired surface finish while maintaining chip control.

Does the insert require a specific toolholder type?
A rigid toolholder with correct seat support for rhombic 55° inserts and secure clamping is recommended to exploit the DNMG110412-MW5 WKK10S’s stability and edge life.
