ZDGT15A408R-K85 WMG40 milling indexable insert — 15° relief, R0.8, Walter Tools

The ZDGT15A408R-K85 WMG40 is a coated carbide milling indexable insert engineered for consistent chip evacuation and repeatable edge performance in general milling applications where process stability is required.

• Coated carbide grade WMG40
• 15° relief angle
• 0.8 mm corner radius
• K85 chipbreaker

Designed for stable, repeatable milling performance

The insert offers a coated carbide composition in the WMG40 grade, tailored to provide a balance between wear resistance and edge robustness. The 15° relief supports reliable entry and exit behaviour in a broad range of milling operations, while the R0.8 corner radius contributes to a stronger cutting edge and predictable surface finish. These geometry choices reduce the need for frequent index changes and support longer uninterrupted machining runs, delivering tangible gains in throughput and tool utilisation.

Controlled chips and fewer process interruptions

A dedicated K85 chipbreaker promotes effective chip control across varying cut conditions, lowering the risk of recutting and machine downtime. The insert’s chipforming characteristics are particularly useful in mixed-production environments where quick changeovers and consistent evacuation are essential. By combining an engineered chipbreaker with the WMG40 cutting material, the solution aims to maintain stable cutting forces and reduce unexpected cycle variations, which benefits both single-piece and serial production.

Clear specification for integration and planning

Key specification details — A4 thickness, tolerance class G and the ISO designation — make integration into toolholders and process documents straightforward. The standardised dimensions enable predictable seat fit and clamping behaviour, simplifying tool assembly and logistics. For workpiece material selection, the WMG40 grade’s suitability should be verified against the manufacturer’s product matrix to ensure optimal performance for the intended application.

Practical advice for selection and use

When choosing an insert for a specific milling task, consider the intended material, desired surface quality and machine rigidity. The combination of WMG40 chemistry, K85 chipbreaker and the defined geometry supports a wide spectrum of milling tasks, but verifying cutting data and recommended feed/speed ranges with technical documentation avoids performance surprises. For application-specific recommendations, the supplier can provide machining data and compatibility guidance to match the insert to the operation.

FAQ

What edge geometry does the insert feature?
The insert features a 0.8 mm corner radius and a 15° relief angle, which are chosen to balance edge strength and entry behaviour for milling operations with the WMG40 grade.

Which chip control solution is integrated?
This milling insert is equipped with the K85 chipbreaker to promote reliable chip formation and evacuation under varying cutting conditions.

Is WMG40 suitable for all materials?
The WMG40 grade is a coated carbide formulation; suitability for specific materials should be checked in the product matrix and technical documentation before application.

How is the insert specified for toolholding?
Dimensions such as 15 mm plate size, A4 thickness and tolerance class G are standardised to support consistent seating and clamping in compatible toolholders.

Can the insert be used for heavy roughing?
The geometry and chipbreaker aim to provide robustness, but recommended cutting parameters and the workpiece material must be verified to confirm suitability for heavy roughing.
