Claim 8:
9. The method as claimed in claim 6, the PCD material comprising:
a first PCD portion coterminous with the distal PCD end; and
a second PCD portion, the first portion extending from the distal PCD end to an interface boundary with the second PCD portion;
the first PCD portion comprising a network of interstitial voids among the diamond grains and being electrically insulating; the method including allowing molten metallic join material to infiltrate into the first PCD portion by moving through the interstitial voids to form the connection portion; wherein
the interface boundary is sufficiently remote from the distal PCD end that the connection portion is spaced apart from the second PCD portion by an electrically insulating region of the first PCD portion.
