| 1. A method of making a weldable ultrahard insert, comprising the steps of:
a) charging a reaction vessel with an ultrahard material;
b) placing a weldable metal layer adjacent the ultrahard material in the reaction vessel to form a precursor assembly; and
c) subjecting the precursor assembly to a pressure and a temperature sufficient to metallically bond the weldable metal layer
to the ultrahard material.
