    if this perpetuates the argument , oh well, guys , if I,m drilling with a diamond bit, into rock that is under heavy pressure(10,000 feet down hole)I,m drilling into formations that are softer than my diamond bit. sometimes we loose the cutting diamonds, but this isn't to tell anyone their wrong or right, I have to change my bit because of the rounding off of the corners , so diamonds will wear down, even against a softer substrate.

    now after a bit hits my doghouse its sent to the lab. there I get a report and analysis on the wear and failure points of the bit, almost always there is a heavy wear of the sharp corners.

    now under normal circumstances, I agree is tough to wear a diamond in short periods of time, but they do wear. I,ll have a bit on surface hear in the next week that has to be swapped because of the wear.

    but really guys is this worth arguing about? not really its just shaving! shave on my friends,( Kyle, diamonds aside, the razor is smooth still)

    Yep, they often cleave away the parts that are likely to break on their own or those that have large internal defects. Cleaving can also be used to roughly shape the stone before it's "cut" or abraded.

    Are you conceding that some abrasion does occur? The linked blog post only further proves my point. Todd (an "internet" friend of mine, BTW - we've discussed this and several other of his blog posts over email quite a few times) only did a few minutes worth of break-in on the depicted diamond plate and he mentions in several places that the diamonds have been worn - or "smoothed" - at the points on the diamonds that made contact with the Shapton hone.

    Its not my fault you can't comprehend the difference between rounding edges and fractured edges. I'm done, I give up. As they say, you can't fix stupid.
    BTW, here is one of the first links from the Google search "can diamond be abraded" - which I advised you to do right from the start:

    I can respond to this question with quotes, if you like. Then I close the thread for review. Your choice.
