Drilling a hole through an insulated wall usually results in a massive birds nest as the fibreglass insulation wraps around the bit. Came up with this idea today,
I needed to run 1 inch conduit through the back wall of the shop. First I used a hole saw to cut through the inside sheeting. Then simply pushed the tubing covered bit through the insulation. While holding the tube against the outer sheeting I drilled through. No birds nest. Then used a hole saw from the outside with the pilot hole to locate it.

Free advice is worth exactly what you payed for it.
