PCD Insert (Nib) Sizes

Polycrystalline dies use an abrasion-resistant PCD insert (nib) at the core of each die. Typically the selection of the insert is based on the hole sizes for the die (new & recut sizes).

Grain Size

The properties of the PCD material can be manipulated by changing the size of the diamond powder before sintering. Surface finish of the wire and life of the die vary the most with changes in grain size.
