By studying the application of sandwich-structured synthetic diamond corebits, following results are concluded: Matrix hardness can be HRC3-5 higher than that of similar ordinary ones;
Gladly I've forgotten quite a lot of the stuff I learnt as a literature student-especially those inward-to-the-corebits complete with angst and those me-against-the-world pontifications.
