ZDGT15A440R-K85 WMG40 T Wendeplatten - Walter Tools

The combination of a coated cemented carbide grade (WMG40) and a K85 chipbreaker delivers stable chip formation and consistent cutting performance; the 15° relief angle plus a 4 mm corner radius further enhance edge stability for productive milling. Order the insert through Metav Werkzeuge or consult the technical team for machining compatibility.

ZDGT15A440R-K85 WMG40 milling indexable insert — 15° relief, 4 mm corner radius (Walter Tools)

The ZDGT15A440R-K85 WMG40 is a coated carbide milling indexable insert designed for standard milling applications where controlled chip formation and a reliable cutting edge are required.

Coated cemented carbide grade WMG40 15° relief angle for consistent cutting Chipbreaker K85 for effective chip control 4 mm corner radius for increased edge strength

Consistent cutting performance from a coated carbide grade

The insert uses the WMG40 coated carbide class, a coated cemented carbide designed for balanced wear resistance and versatility. The 15° relief angle reduces rubbing and improves chip flow, which in turn lowers cutting forces and contributes to a more stable machining process. For shops seeking predictable cycle times, this geometry supports repeatable results and reduces the risk of premature edge wear. Check the product matrix for exact material suitability before series production to ensure optimal results.

Reliable chip control and process security

Equipped with the chipbreaker K85, the insert promotes defined chip segmentation and evacuation, helping to avoid tangling and heat concentration. The combination of the chipbreaker and the 4 mm corner radius provides a compromise between edge strength and surface finish — beneficial when tool life and component quality are priorities. The designation and execution codes indicate standardised geometry for simple tool handling and predictable replacement intervals.

Standard format and handling for efficient tool changeovers

With a plate size of 15 mm and a coded thickness A4, the insert fits common milling toolholders and supports fast indexable replacement, reducing downtime. The nominal designation ensures compatibility in procurement and tool inventory management. The manufacturing tolerance class G denotes consistent dimensional precision, which simplifies setup and reduces scrap from misalignment. This insert is suited to production environments where process stability and economical machining are required.
