ZDGT20A550R-K85 WMG40 milling indexable insert — Walter Tools, 15° relief & K85 chipbreaker

The ZDGT20A550R-K85 WMG40 is a precision milling indexable insert designed for general milling applications; it combines a coated-carbide grade with a K85 chipbreaker for predictable chip formation and consistent edge stability.

• Coated carbide grade WMG40
• 15° relief angle for stable cutting
• 5 mm corner radius for robust edge
• K85 chipbreaker for reliable chip control

Increased process reliability for stable machining

The combination of a WMG40 coated-carbide grade and a defined 15° relief angle reduces cutting forces and contributes to consistent engagement during milling. This technical pairing promotes stable chip formation, which in turn minimises tool vibration and helps maintain dimensional accuracy across batches. For production environments where repeatability matters, the insert’s geometry supports steady metal removal and reduces the need for frequent rework.

Robust edge life and wear resistance

A 5 mm corner radius and the coated-carbide construction provide a durable cutting edge capable of withstanding intermittent heavy cuts. The coating and substrate combination improves resistance to adhesive and abrasive wear, extending effective tool life under varied conditions. As a result, machining cycles can run longer between indexings, helping to maintain throughput without sacrificing surface quality.

Predictable chip control and machining outcomes

The integrated K85 chipbreaker is engineered to control chips in a wide range of cutting conditions, improving evacuation and reducing the risk of recutting. Better chip management leads to improved surface finish and easier handling at the machine. Because the material specification is catalogue-dependent, verification against the product matrix is recommended to confirm suitability for specific alloys or machining strategies.

Practical guidance for application and selection

This insert is supplied in the ZDGT20A550R-K85 designation and should be matched to appropriate cutter bodies and clamping systems. The plate thickness and form (A5) and the tolerance class G ensure compatibility with standard milling holders; consult the product matrix where necessary. For unfamiliar materials or critical surface requirements, trial cuts and parameter optimisation will secure the best combination of feed, speed and coolant strategy.
