Drawing dies were manufactured from polycrystalline diamonds and tested under operating conditions. The surface was examined using optical and scanning electron microscopy after different stages of fabrication and use. The quality of polycrystalline diamond, tool manufactoring process, and drawing parameters controlled the type of damage. The lifetime of a PCD die is 3 to 8 times larger than that of natural diamond dies and 20 to 200 times larger than tungsten carbide dies.
