ZDGT20A516R-K85 WMG40 indexable milling insert, K85 chipbreaker (15°) — Walter Tools

The ZDGT20A516R-K85 WMG40 is an indexable milling insert engineered for stable milling operations across a range of workpiece materials; designed primarily for industrial metalcutting where reliable chip formation and repeatable edge life are required.

• Coated carbide grade WMG40
• K85 chipbreaker for chip control
• 15° relief angle for stable cutting
• 1.6 mm corner radius for robustness

Consistent chip control and efficient material removal

The combination of the K85 chipbreaker and the WMG40 coating provides controlled chip formation, which reduces interruptions and promotes continuous material removal. The insert's geometry is optimised to produce short, manageable chips under a variety of cutting conditions; this leads to fewer downtimes for chip clearing and contributes directly to higher process efficiency. The clear, engineered chip flow also helps to reduce heat concentration on the cutting edge, supporting longer tool life and more predictable component quality.

Reproducible edge life and cutting stability

With a 15° relief angle and a 1.6 mm corner radius, the insert is designed to balance sharpness and edge strength. The specified relief minimises rubbing while maintaining sufficient support behind the cutting edge, and the larger corner radius enhances resistance to edge chipping during interrupted cuts. Specified tolerance class G and A5 thickness provide mechanical stability in the toolholder, which translates to consistent dimensional accuracy on the workpiece and fewer rejects during production.

Material guidance and process integration

The WMG40 grade is a coated carbide formulation intended for versatile performance; however, the exact suitability for specific alloys should be verified against the manufacturer's product matrix. Material data are catalogue-dependent and must be checked prior to application to ensure optimal cutting parameters. For integration into an existing toolchain, documentation of cutting conditions and a short trial run are recommended to confirm feeds and speeds, chip behaviour, and surface finish under the given machine and clamping conditions.

FAQ

What materials is this insert suited for?
The ZDGT20A516R-K85 WMG40 insert uses the WMG40 coated carbide grade and can machine a broad range of materials; exact compatibility should be checked in the Walter Tools product matrix for the specific workpiece alloy.

How does the K85 chipbreaker influence machining performance?
The K85 chipbreaker promotes controlled chip formation and evacuation, improving machining continuity and reducing the risk of chip-related interruptions when using the ZDGT20A516R-K85 WMG40 indexable insert.

What do the geometry values mean for process reliability?
A 15° relief angle reduces rubbing while maintaining support behind the edge, and the 1.6 mm corner radius increases edge robustness; together these features enhance stability and repeatable edge life for the ZDGT20A516R-K85 WMG40.

Is the WMG40 grade a coated or uncoated substrate?
The WMG40 designation refers to a coated carbide grade as specified by Walter Tools; further substrate details are catalogue-dependent and should be consulted in the product documentation.

What tolerance and thickness specifications apply to this insert?
This insert is specified with tolerance class G and a plate thickness A5, which support dimensional consistency and mechanical stability in standard toolholders when using the ZDGT20A516R-K85 WMG40.
