    Hi Les, Its not very often someone mentions a tool with which I'm
    unfamiliar, but you got me! What is a centering drill... and how does
    it control the depth of the hole? I'm thinking of a drill press with
    a depth-stop, but I don't think that would work for sheet metal. You
    must be talking about something else?
