I've never had a problem, and I also use a cone cut bit, especially in plastics. You need
to make a large hole for the bolt on an 85 mm cutter.

If you have a couple of thin pieces of ally scrap, use them both sides of the diecast box
wall this will reduce the risk of fracture. It is imperative that the bolt and cutter are
well lubricated.
