[sdiy] Drilling 'square' holes

[Rob]

Go to ratshack and buy a metal nibbler while you still can.. They are only 9
dollars!!!
Very difficult to find, but ratshack has em in stock for now.

You drill a hole a bit smaller than what you want, then use the nibble tool
to square it off.. Works great, and no little metal bits everywhere.
