Abstract
A method of making a cutter structure () comprises placing a pre-formed body () of hard material having a surface topography in a canister, placing an aggregated mass of grains of superhard material () over said surface topography, placing a punch () in contact with the superhard material (), the punch () having a surface with a surface topography inverse to that of the hard material body to imprint a pattern in the superhard material () complementary to the surface topography of the punch (). The surface of the punch () contacting the superhard material () being formed of a ceramic material that does not react chemically with the superhard material () and/or a sinter catalyst for the superhard material (). A pressure of greater than 3 GPa is then together with a temperature sufficiently high for the catalyst to melt to form the cutter structure () with a layer of polycrystalline superhard material bonded to the hard material and having a surface topography corresponding to the surface topography of the hard material.
