ZDGT200508R-K85 WNN15 milling indexable insert — chipbreaker K85, 15° relief, Walter Tools

ZDGT200508R-K85 WNN15 is a milling indexable insert designed for versatile milling tasks in industrial production, featuring a chipbreaker for controlled chips and a geometry optimised for repeatable results

• Coated carbide grade WNN15
• Chipbreaker K85 for consistent chip control
• 15° relief angle for versatile milling
• 0.8 mm corner radius for reliable edge strength

Increased productivity through controlled chip formation and stable cutting

The coated carbide composition of this insert (grade WNN15) combines wear resistance with reliable cutting performance, making it well suited to production environments where predictable tool life matters. The integrated chipbreaker K85 reduces long, stringy chips and promotes efficient evacuation, which in turn supports higher feed rates and reduces downtime for chip clearing. With a 15° relief angle, the geometry offers a balance between strength and cutting action, enabling consistent surface finish and improved cycle times in repetitive milling operations. The insert designation appears as ZDGT200508R-K85 WNN15 in technical documentation.

Clear technical advantages explained for practical decision‑making

The 0.8 mm corner radius strengthens the cutting edge and improves resistance to edge chipping during interrupted cuts, while the chipbreaker design shapes the chip to limit heat concentration and machine wear. These characteristics translate into fewer tool changes and more stable process windows on CNC milling centres. The insert’s coded thickness and plate size are supplied as specified; for exact workpiece compatibility and cutting data, please consult the product matrix—the material suitability must be checked against the specific application. This pragmatic overview supports selection decisions in job shops and volume production alike.

Reliability, brand backing and application orientation

Walter Tools’ engineering pedigree ensures the insert is manufactured to tight tolerance standards and designed for repeatable performance in demanding machining scenarios. The combination of coated carbide, a proven chip control geometry and a moderate relief angle delivers a tool solution that favours longer edge life and consistent part quality. For manufacturers seeking process stability and predictable tool behaviour, this variant offers a technically clear, application‑oriented option that integrates into existing tool systems with familiar handling and indexable insert workflows.

FAQ

What materials is this insert suitable for?
Material suitability should be checked against the product matrix; the WNN15 grade is a coated carbide designed for a broad range of applications, but specific workpiece compatibility must be verified for the intended machining task.

How does the chipbreaker K85 affect performance?
The K85 chipbreaker shapes and breaks chips to improve evacuation and reduce heat build-up, leading to more stable cutting conditions and fewer interruptions for chip removal when using ZDGT200508R-K85 WNN15 inserts.

What does the 0.8 mm corner radius mean for milling results?
A 0.8 mm corner radius increases edge robustness and resistance to chipping during interrupted cuts, which helps maintain surface quality and prolong tool life under mixed cutting conditions.

Is the relief angle fixed and what is its benefit?
The relief angle is 15°, which balances cutting aggressiveness with edge strength to provide versatile performance across a variety of milling operations.

Where can further cutting data be obtained for this insert?
Cutting parameters and application guidance are available from Metav Werkzeuge; consult the technical documentation and product matrix to match ZDGT200508R-K85 WNN15 to the specific machine, holder and workpiece material.
