Abstract: This disclosure relates to a method of making a shaped tool component from a precursor sintered body comprising polycrystalline diamond (PCD). The sintered body has a PCD table joined to a substrate, and the PCD table varies in depth. The resulting shaped tool component thus also has a PCD layer with varying depth. A method of making a shaped tool component comprising polycrystalline diamond (PCD), comprising the steps: h. Adding a diamond feed stock to a refractory cup; i. Adding a p re-shaped cemented carbide body to the refractory cup adjacent the diamond feed stock; j. Compacting the diamond feed stock and cemented carbide body to form a green body; k. Sintering the green body at a temperature between 1400° C. to 2100° C. and at a pressure of at least 7 GPa, for at least 30 seconds to form a sintered PCD precursor body that comprises a PCD table sinter-joined to the cemented carbide substrate at an interface;
