Polycrystalline diamond compacts, polycrystalline diamond blanks, polycrystalline diamond cutters, and tools incorporating same for cutting, milling, grinding, drilling and other abrasive operations, particularly in metal cutting applications, include a diamond table having a gradient in iron content that increases as distance into the volume of the diamond table increases. The iron gradient increases resistance to wear, such as in interrupted milling tests. The disclosure further relates to methods of manufacturing polycrystalline diamond compacts having a gradient in iron concentration in the diamond table, blanks and cutters including polycrystalline diamond compacts, cutting tools incorporating such compacts, blanks and cutters, and methods of cutting, milling, grinding and drilling, particularly metal machining, using such compacts, blanks, cutters, cutting tools and drill bits.
