BCGT090304R-B85 WDN20 Parallelogram 75° PKD milling insert by Walter Tools

BCGT090304R-B85 WDN20 is a polycrystalline diamond (PKD) milling insert designed for high‑wear, non‑ferrous applications such as abrasive aluminium alloys and other challenging non‑ferrous materials

• PKD cutting grade WDN20 for abrasive non‑ferrous metals
• Parallelogram 75° form for versatile milling
• 7° clearance angle for reduced rubbing
• 0.4 mm corner radius for defined edge stability
• B85 chipbreaker for controlled chip formation

Reliable performance for abrasive non‑ferrous milling

The insert is manufactured in the WDN20 grade, a PKD formulation chosen for its exceptional wear resistance when machining abrasive, non‑iron materials. This makes the component particularly suitable where rapid flank wear would otherwise shorten tool life. The combination of a hard cutting layer and the specified chip control geometry reduces flank contact and helps to maintain a consistent cutting edge, which supports predictable process planning and reduces unscheduled tool change interventions.

Stable edge life and predictable surface results

With a 0.4 mm corner radius and a 7° clearance angle, the geometry is tuned to balance edge strength and surface finish. The moderate corner radius delivers improved edge stability during interrupted cuts while the clearance angle minimises rubbing at the flank, contributing to lower cutting temperatures and fewer built‑up edge issues. The integrated B85 chipbreaker moderates chip size and evacuation, which aids coolant access and supports repeatable surface quality across series production.

Practical integration and application guidance

The Parallelogram 75° form provides flexibility in toolholder choice and entry angles, enabling use in a range of shoulder and face milling operations. Where process security is critical, the insert’s characteristics support stable feeds and optimised chip control; however, the specific workpiece alloy and machining strategy should be checked against the manufacturer’s product matrix before selection. For application optimisation, match the insert geometry with appropriate clamping and holder specifications to exploit the PKD edge’s advantage in abrasive non‑ferrous machining.
