    I make the mistake a few months ago of buying a set of Hardinge collets ... worst collets I have ever seen. Have to use a pipe wrench on a 5-c electric collet head to hold on-size stock.

    This is just like leaving a chuck wrench in a lathe chuck ... teach yourself not to do stupid stuff (I know, but try; I'm slowly getting better)

    Use a small plug gage. You can even 'sharpen' the end by grinding a little off of the length. You should be able to feel it drop in even though it's only 0.014 deep.

    And there you have it ... that is what passivation is for! Make your tooling from D-2 so it will last, and advise the customer to have his parts passivated. It's cheap!

    Soap and water comes to mind. The graphite sticks to the oil film that accrues on the sheet metal. Simple soap and water is enough to cut that thin film, and the graphite comes off with it.
