ZDGT15A420R-K85 WMG40 — Indexable milling insert, 15° clearance, K85 chipbreaker (Walter Tools)

ZDGT15A420R-K85 WMG40 is a coated carbide indexable milling insert intended for versatile milling tasks; it combines a 15° clearance angle with a K85 chipbreaker for controlled swarf evacuation.

• Coated carbide grade WMG40
• 15° clearance angle for smooth cutting
• K85 chipbreaker for stable chip control
• 2 mm corner radius for robust edge life

Consistent cutting performance for reliable cycle times

The WMG40 grade is a coated carbide designed to offer a balanced combination of wear resistance and toughness. With a 15° clearance the geometry reduces rubbing on the flank face and helps maintain cutting stability, which is particularly relevant in peripheral milling or interrupted cuts. The integrated K85 chipbreaker supports controlled chip formation, lowering the risk of built-up edge and helping to keep tool-change intervals predictable. These features contribute directly to shorter non-productive time and improved process reliability without sacrificing surface quality.

Guidance on applications and material suitability

Material suitability for this insert is catalogue-dependent and should be verified against the product matrix provided for the WMG40 family. The insert’s open series designation means it is intended for a broad range of tasks within the limits of the defined grade; however, confirmation for specific alloys and hardness levels is recommended. Technical advisors can provide cutting data and adapt parameters to the machining centre in use. This approach enables a tailored balance between cutting speed, feed and tool life, offering cost-effective productivity for batch and continuous operations.

Precision design that supports repeatable results

A 2 mm corner radius delivers a compromise between edge strength and form accuracy, improving resistance to chipping during indexed operations. The insert is manufactured to tolerance class G, providing dimensional consistency for fixture-based processes and automated tool changers. The specified A4 thickness and execution code T ensure compatibility with common milling cutter bodies that accept this insert family. Together, these design details support reproducible part quality and help to reduce scrap rates in high-volume production.
