ZDGT200520R-K85 WNN15 — indexable milling insert, K85 chipbreaker, 15° relief (Walter Tools)

The ZDGT200520R-K85 WNN15 is an indexable milling insert designed for versatile metal machining applications, combining a coated-carbide grade with a K85 chipbreaker to support controlled chip evacuation and reliable performance.

• Coated carbide grade WNN15 for general machining
• K85 chipbreaker for reliable chip control
• 15° relief angle for stable cutting geometry
• 2 mm corner radius for robust edge strength

Consistent cutting performance for mixed-material production

The insert is based on a coated carbide grade that aims to deliver stable chip formation and broad workpiece coverage. The WNN15 grade is engineered for general machining tasks where a balance between wear resistance and toughness is required; this results in more predictable tool behaviour across varying batches. Using a defined chipbreaker geometry reduces the risk of irregular chips, which in turn supports continuous production and fewer interruptions for manual chip clearing. The design therefore supports higher uptime in milling operations and helps to maintain surface quality without frequent insert changes.

Built-in durability and precise edge geometry for longer tool life

A 2 mm corner radius together with the specified 15° relief angle produces a robust cutting edge that resists chipping under moderate loads and promotes even wear distribution. The K85 chipbreaker further contributes to controlled cutting forces and reduced vibrations, which benefits both component finish and insert lifetime. For process planners this combination means more consistent cycle times and improved repeatability when set-up data are transferred between machines; the geometry supports a favourable compromise between strength and sharpness for typical finishing and semi-finishing passes.

Practical application and integration into production workflows

As an indexable milling solution, the insert fits established toolholders that accept the ZDGT geometry and enables quick indexing to restore a fresh cutting edge. The ZDGT200520R-K85 WNN15 is supplied in a standard form factor that eases inventory handling and simplifies tool selection for production engineers. Material suitability should be verified against the supplier’s product matrix, but the coated-carbide class and chipbreaker design make the insert a practical choice for mixed-material shops seeking predictable chip control and straightforward integration into existing milling tool systems.
