Question - What is the largest size hole that can still be repaired?

Answer - The stepped core drill bit diameter is 31/64" or 12.3mm. Therefore the hole ideally would be smaller than that so that when it's drilled a nice smooth hole will be made to accept the tap creating full threads to accept the insert.
