ZDGT20A530R-K85 WMG40 milling insert — Walter Tools — 15° relief, 3 mm corner radius

ZDGT20A530R-K85 WMG40 is a milling indexable insert designed for productive machining where consistent edge life and controlled chips are required

• Coated carbide grade WMG40 for wear resistance
• 15° relief angle for stable milling
• 3 mm corner radius for enhanced edge strength
• K85 chipbreaker for controlled chip formation

Increased process reliability through a modern coated grade

The WMG40 grade is specified as a coated carbide cutting material and provides a baseline for wear resistance and repeatable performance. The coated substrate supports longer tool life under varied operating conditions; however, material compatibility should be checked against the manufacturer product matrix before final selection. This insert designation, ZDGT20A530R-K85 WMG40, allows predictable indexable performance and reduced unplanned downtime when integrated into a matched toolholder and cutting data set.

Geometry tuned for consistent surface quality and edge life

A 15° relief angle and a 3 mm corner radius combine to deliver both cutting stability and edge strength. The relief angle reduces rubbing and heat build-up, while the larger corner radius disperses cutting forces across a broader edge, improving resistance to chipping during interrupted cuts. These geometric choices translate into more consistent surface finish and extended intervals between insert changes when the machining parameters and feed conditions are adapted to the component geometry.

Controlled chip formation to support efficient production

The K85 chipbreaker is engineered for reliable chip control in typical milling tasks, helping to avoid entanglement and enabling uninterrupted chip evacuation. Better chip management lowers cycle-time variability and reduces the need for secondary cleaning operations. In production contexts where repeatability and process stability are priorities, the chipbreaker design helps maintain tool performance across batches.

Practical identification and inventory benefits

The base designation ZDGT20A530R-K85 and the clear grade marking WMG40 simplify stock management and reorder planning. The tolerance class G and the specified thickness and shape codes permit easy cross-referencing with toolholder specifications and NC programmes. For precise application guidance and to confirm suitability for specific materials or cutting strategies, Metav Werkzeuge’s technical advisers can provide the validated cutting data required for a safe and productive implementation.

FAQ

What materials is this insert suitable for?
Material compatibility depends on the chosen cutting data and the product matrix; the ZDGT20A530R-K85 WMG40 insert is a coated carbide grade and suitability should be checked against the manufacturer’s application chart.

How does the K85 chipbreaker affect machining?
The K85 chipbreaker promotes controlled chip formation, aiding chip evacuation and reducing the risk of entanglement during milling with this milling insert.

Can the corner radius be changed for different finishes?
Different corner radii offer trade-offs between edge strength and surface finish; the 3 mm corner radius on this insert prioritises edge robustness for interrupted or heavy cuts.

How can the insert be identified for reordering?
Use the full designation ZDGT20A530R-K85 WMG40 and the SKU ZDGT20A530R-K85-WMG40-WALTER when reordering to ensure the correct Walter Tools grade and geometry are supplied.
