Abstract
A polycrystalline diamond compact (PDC) cutter having a body of diamond crystals containing a catalyzing material is coated with a material impervious to a given acid. After the coating has dried, a segment of the coating is removed and acid is supplied to the diamond crystal body through the template in the coating to leach out the catalyzing material contained within the body of diamond crystals.
