SDGW09T3AZR-A88 WDN20 milling indexable insert by Walter Tools — PCD grade for non‑ferrous, abrasive applications

The SDGW09T3AZR-A88 WDN20 is a precision milling indexable insert developed for high‑wear machining of non‑ferrous and abrasive non‑ferrous materials, combining a robust square 90° form with a specialised chipbreaker for stable cutting.

• PCD grade WDN20 for abrasive materials
• Square 90° geometry for high rigidity
• 15° clearance angle for consistent cutting
• A88 chipbreaker for controlled chip formation

Maximise uptime with a wear‑resistant PCD grade

The insert’s core advantage is the polycrystalline diamond (PCD) grade WDN20, which delivers markedly higher wear resistance when machining abrasive non‑ferrous materials such as certain aluminium alloys and other non‑ferrous alloys with hard inclusions. This results in longer intervals between index changes and reduced machine downtime, improving process economics in volume milling operations. The combination of PCD and the A88 chipbreaker further supports consistent chip evacuation, which minimises rework and tool‑related interruptions.

Stable cutting geometry for reproducible surface quality

Designed in a square 90° form with a 15° clearance angle and T3 plate thickness, the insert provides a stable cutting edge and predictable contact geometry. The square profile increases support in the pocket and reduces bending loads during side milling, which helps to maintain a uniform surface finish across batches. For operations where dimensional consistency matters, the geometry contributes directly to process stability and reduces the need for frequent fine adjustments on the machine.

Practical handling and application guidance for reliable results

The A88 chipbreaker is optimised for controlled chip segmentation under typical milling feeds used for non‑ferrous alloys; correct feed and speed selection ensures the chipbreaker functions as intended. While the grade and chipbreaker are suited to abrasive, non‑ferrous workpieces, it is important to check the product matrix for specific workpiece‑grade compatibility and recommended cutting data. Clamping integrity and correct seat cleanliness are essential to exploit the insert’s rigidity and to avoid undesired tool movement.

Why this insert fits production environments

This indexable solution is aimed at shops and production lines seeking predictable tool life and process reliability when facing abrasive non‑ferrous materials. The combination of WDN20 PCD, A88 chip control, and the 90° form reduces the risk of premature wear and improves throughput. For application advice or assistance in selecting the correct seat and clamping system, technical consultation is available to match the insert to the machine and machining strategy.

FAQ

What materials is this insert intended for?
The SDGW09T3AZR-A88 WDN20 insert is specified for non‑ferrous and abrasive non‑ferrous materials; verify compatibility with the product matrix for exact alloys.

How does the PCD grade affect tool life?
The WDN20 PCD grade offers high wear resistance in abrasive non‑ferrous applications, which typically extends tool life compared with carbide alternatives.

Which chip control is provided by the insert?
The integrated A88 chipbreaker is designed to promote controlled chip formation and evacuation at the recommended cutting data.

Is the square 90° form suitable for shoulder milling?
Yes—the square 90° geometry provides increased rigidity for shoulder and face milling operations where a robust edge is required.

Where to get cutting data and application advice?
