This is used as a drill bit a cutting element (10) A method of manufacturing a polycrystalline diamond (PCD) cutting element is disclosed. Method substantially all of the binder from the portion of the cutting surface of the PCD body - and a step of leaching the PCD body formed from diamond particles (202) by using the catalyzed material-binding agent to remove the catalyzing material. Portion of the cutting surface 24 is, in use of the cutting element to cut the material identified as a cutting zone which is heated by the cutting action of the cutting element. Leaching of the PCD body involves performing relatively shallow leaching to at least a portion 26 of the cutting surface is with performing the relatively deep part of the leaching of the cutting plane identified as the cutting area, the cutting area surrounding the identified.
