    Drilling a fiberglass enclosure?

    I'm working on getting some boards/switches mounted in my control panel and have drilled some holes for sensor connections but they came out lousy (very frayed on the inside). I have a spade bits for the larger holes. So, what is the best way to drill a clean hole through fiberglass?
