ZDGT150404R-K85 WNN15 indexable milling insert — 15° clearance, 0.4 mm corner radius (Walter Tools)

A ZDGT150404R-K85 WNN15 indexable milling insert designed for general milling operations where robust chip control and repeatable edge stability are required.

• Coated carbide grade WNN15 for broad application
• 15° clearance angle for versatile milling
• K85 chipbreaker for consistent chip formation
• 0.4 mm corner radius for defined edge strength

Reliable cutting performance for demanding production

The insert delivers consistent cutting behaviour through a combination of a modern coated-carbide grade and a dedicated chipformer. The WNN15 grade denotes a coated hardmetal designed to offer a balance between wear resistance and toughness; this supports longer tool life under variable cutting conditions. Coupled with the K85 chipbreaker, chips are guided predictably away from the cutting zone, reducing interruptions and improving cycle-time reliability. These technical choices translate into measurable production benefits: fewer index changes, improved surface finish stability and lower process variability.

Geometry that secures dimensional accuracy and edge life

The geometry of the insert—notably the 15° clearance angle and the 0.4 mm corner radius—is engineered to combine cutting efficiency with reliable edge strength. The clearance angle reduces rubbing on the flank face, lowering heat generation and preserving the cutting edge during interrupted cuts. Meanwhile, the small corner radius provides a defined cutting edge that supports repeatable feature definition on workpieces. The combination is particularly useful where controlled chip removal and precise edge definition are priorities; tolerance class G contributes to consistent seating and repeatable positioning in toolholders.

Selection guidance and practical application notes

Material suitability is indicated by the coated-carbide character of the grade, but specific application limits should be verified against the manufacturer matrix; the material information is catalogue dependent. Where the workpiece material is uncertain, reference to the product matrix or a cutting-data sheet is recommended to match feed and speed recommendations to the insert’s capabilities. For integration into existing tool assemblies the insert carries the ISO designation ZDGT150404R-K85 WNN15, enabling straightforward cross-referencing. For bespoke advice on cutting parameters or compatibility with certain steels, aluminium alloys or other substrate groups, Metav Werkzeuge can provide tailored recommendations and cutting-data assistance.

FAQ

What materials is the insert suitable for?
The insert is supplied in the WNN15 coated-carbide grade; material suitability should be checked in the manufacturer's product matrix and cutting-data documentation for the ZDGT150404R-K85 WNN15 insert.

How does the K85 chipbreaker affect machining?
The K85 chipbreaker promotes predictable chip formation and evacuation, which reduces the risk of built-up edge and helps maintain a consistent surface finish during milling.

What does the 15° clearance angle mean for cutting performance?
A 15° clearance angle reduces flank contact and heat at the cutting edge, improving tool life and performance during operations with interrupted cuts or varying depths of cut.

Is the corner radius suitable for finishing passes?
The 0.4 mm corner radius offers a defined cutting edge that can be used for finishing where a small, consistent radius is required; for ultra-fine finishes, selection of final-pass parameters is recommended.

How can the insert be ordered or specified for tool assemblies?
Specify the ISO designation ZDGT150404R-K85 WNN15 and Walter Tools as the manufacturer when ordering to ensure correct matching to the toolholder and process requirements.
