ZDGT200530R-K85 WNN15 indexable milling insert — Walter Tools, K85 chipbreaker, 15° relief

ZDGT200530R-K85 WNN15 is an indexable milling insert designed for productive milling operations where stable chip formation and repeatable edge life are required

Coated carbide grade WNN15
K85 chipbreaker for stable chip control
15° relief angle for versatile milling
Corner radius R3 for reliable edge strength

Engineered for stable chip formation and higher productivity

The insert is based on the WNN15 coated carbide grade and is shaped to promote stable chip formation under a wide range of cutting conditions. The integrated K85 chipbreaker optimises chip flow during interrupted and continuous cuts, reducing the risk of built-up edge and improving process reliability. By combining a wear-resistant coating with a balanced geometry, this solution aims to extend the tool life and maintain consistent component quality, which supports higher effective productivity in series production.

Geometry that balances strength and surface finish

A 15° relief angle and a corner radius R3 provide a compromise between cutting edge strength and achievable surface finish. The moderate relief angle contributes to lower cutting forces in many milling operations, while the R3 corner increases resistance to chipping on entry and exit. This geometry is particularly useful when machining with variable engagement or when surface quality and dimensional repeatability are priorities, allowing operators to obtain consistent results with fewer insert changes.

Coating and grade explained — what WNN15 delivers

The WNN15 designation indicates a coated carbide grade optimised for a broad range of materials; the coating improves wear resistance and thermal stability at the cutting zone. The specific substrate and coating stack are catalog-dependent, so the final composition and recommended cutting parameters should be checked in the product matrix. The combination of coating and K85 chip control is intended to reduce downtime for regrinding and replacement, contributing to lower process costs over the tool life.

Practical integration and recommendations for use

The insert is supplied in the ZDGT geometry and is intended for mounting in compatible indexable milling cutters that accept this ISO-style designation. Tolerance class G ensures dimensional consistency for repeatable indexation and balance. For best results, match the insert to the appropriate cutter body and consult the product matrix for recommended cut data; if material suitability or cutting parameters are unclear, Metav Werkzeuge can provide application advice to align the insert’s strengths with the machining task.

FAQ

Which materials is this insert suitable for?
The ZDGT200530R-K85 WNN15 insert is a coated carbide grade intended for a broad range of materials; specific suitability should be verified in the product matrix for the WNN15 grade.

What benefit does the K85 chipbreaker provide?
The K85 chipbreaker on the Walter Tools insert promotes controlled chip formation and evacuation, reducing build-up and improving process stability during interrupted and continuous milling.

Why is the R3 corner radius important?
A corner radius of 3 increases edge strength and resistance to chipping, which helps achieve more reliable tool life and consistent surface quality with the ZDGT geometry.

Can this insert be used in standard ZDGT holders?
The insert is supplied with the ISO-style designation ZDGT200530R-K85 and is intended for compatible ZDGT holders; correct mounting and clamp type should be checked against the cutter body.

How is the coating specified for this grade?
Coating and substrate details are catalog-dependent for the WNN15 grade; consult the product matrix or Metav Werkzeuge for the definitive coating specification and recommended cutting data.
