ZDGT15A404R-K85 WMG40 Fräswendeschneidplatte (milling indexable insert) – 15° relief, 0.4 mm corner radius – Walter Tools

The ZDGT15A404R-K85 WMG40 is a coated carbide milling insert designed for versatile finishing and semi-finishing operations, combining a controlled chipformer with a low-relief geometry for consistent surface quality.

• Coated carbide grade WMG40
• 15° relief angle for finishing
• 0.4 mm corner radius for accurate edges
• K85 chipbreaker for controlled chips

Longer tool life through optimised carbide and coating

The choice of WMG40, a coated carbide grade, is aimed at increasing tool life under mixed cutting conditions. The coating supports wear resistance and thermal stability so that flank wear develops more slowly; this results in longer intervals between index changes and fewer unscheduled tool changes. For procurement planning, the combination of a robust substrate and surface engineering enables consistent part quality over extended cycles, reducing rework and downtime. Material suitability is determined by the product matrix and should be checked for specific workpiece alloys.

Stable machining and predictable chip formation

The built-in K85 chipbreaker and the 15° relief geometry work together to produce short, controllable chips and to reduce cutting forces during finishing passes. A 0.4 mm corner radius supports accurate edge definition and improved surface finish on shoulder and face milling operations. Technically, the chipbreaker profile interrupts and shapes the swarf while the relief angle minimises rubbing at the cutting edge, which together enhance process stability and allow higher feed rates with maintained surface quality. This results in safer toolpaths and more reproducible cycle times in series production.

Practical notes for application and process integration

The insert is supplied in the standard designation ZDGT15A404R-K85 WMG40 and in a plate thickness specification A4; the actual material variants are listed as catalogue-dependent and should be verified against the workpiece material. The series is identified as an open Walter grade, prioritising broad applicability across several machining tasks. For customers seeking to integrate this insert into existing toolholders and milling systems, checking the insert seat geometry, torque values for clamp screws and recommended cutting data in the tool matrix will ensure optimum performance. For detailed process data and tailored cutting parameters, refer to the product matrix or contact our technical advisors who can provide recommended feeds and speeds based on the workpiece and machine stability.

FAQ

What materials is this insert suitable for?
The WMG40 grade is a coated carbide intended for a broad range of materials; suitability must be verified in the product matrix for the specific workpiece alloy before application.

How does the K85 chipbreaker affect milling performance?
The K85 chipbreaker shapes and breaks chips to improve swarf control and process reliability, which in turn supports safer cutting conditions and consistent surface finishes with the ZDGT15A404R-K85 WMG40 insert.

Which operations benefit most from the 15° relief angle and 0.4 mm corner radius?
Finishing and light semi-finishing passes benefit from the 15° relief and the 0.4 mm corner radius, offering improved edge stability and finer surface quality on shoulder and face milling.

What information is needed to select the correct feed and speed?
Machine power, rigidity, workpiece material and the intended depth of cut are required; Metav Werkzeuge can provide recommended cutting data for the ZDGT15A404R-K85 WMG40 based on these parameters.
