XOEN12T308R-A-A88 WDN20 – Milling indexable insert, PCD grade (Walter Tools)

XOEN12T308R-A-A88 WDN20 is a milling indexable insert designed for high‑wear, high‑precision machining of non‑ferrous and abrasive non‑ferrous materials

• High-wear PCD grade WDN20
• 0.8 mm corner radius for consistent finish
• A-A88 chipbreaker for clean chip control
• Universal 12 mm inscribed circle size

Durable cutting performance for abrasive non‑ferrous workpieces

The WDN20 specification denotes a polycrystalline diamond (PCD) cutting grade engineered for exceptional wear resistance when machining abrasive, non‑iron materials. This makes the insert particularly suitable for applications where surface integrity and long tool life matter, such as machining composites, aluminium alloys with high silicon content and other abrasive non‑ferrous workpieces. The result is fewer tool changes, consistent dimensional accuracy and improved process economy — measurable benefits that support higher productivity and lower per‑part tooling cost.

Geometry and chip control that protect productivity

A precise 0.8 mm corner radius and the A‑A88 chipbreaker geometry deliver stable cutting edges and controlled chip formation. The combination of radius and chipbreaker reduces edge chipping and helps maintain a repeatable surface finish, which minimises rework and downstream finishing. For milling operations demanding fine surface quality and predictable tool behaviour, these geometric features translate into shorter cycle times and more consistent part quality across batches.

Practical guidance and compatibility notes

The insert is listed with a 12 inscribed circle and thickness coded T3, with designation XOEN12T308R‑A‑A88 and execution N. The cutting grade is part of the Walter Schneidstoffsorte — Serie offen and is marked WDN20. As the grade is PCD, suitability for specific alloys should be verified against the manufacturer product matrix before series use. For customers requiring application‑specific recommendations, Metav Werkzeuge’s technical advisors can assist with feed/speed windows and material pairing to ensure optimal results.

FAQ

What materials is this insert primarily intended for?
The XOEN12T308R‑A‑A88 WDN20 insert is intended primarily for non‑ferrous and abrasive non‑ferrous materials; the PCD grade provides long life on such workpieces.

Is the WDN20 grade suitable for steel or iron machining?
Polycrystalline diamond grades such as WDN20 are generally not recommended for ferrous materials due to chemical affinity at cutting temperatures; suitability should be confirmed via the product matrix before use.

What does the A‑A88 chipbreaker deliver in practice?
The A‑A88 chipbreaker promotes controlled chip formation and evacuation, leading to improved surface finish and reduced risk of edge damage during milling.

How does the 0.8 mm corner radius affect results?
A 0.8 mm corner radius balances edge strength and surface quality, offering repeatable edge life and consistent finishing characteristics in intermittent milling or finishing passes.

Where can machining parameters and compatibility be found?
Feed and speed recommendations and material compatibility for the WDN20 grade are available in the manufacturer product matrix and technical documentation for the insert; consult those resources for process optimisation.
