Sounds like a manufacturing defect. They are not pot metal. I have heard of some teams tapping the remaining block. However, there are 25 pins on the bottom that carry the current into the circuit board. Any repairs need to be performed with caution to maintain these paths. Heating of the block and board could result if any of the pins are drilled into and break the bond with the block.
