You might try this method, I have used it on wood jambs with success. You
should be able to adapt it to a metal frame:

Use a 3/4" hole saw with a removeable pilot bit, in a variable speed drill
motor. Push the wire up inside the hole about 1", or more in order to not
touch the pilot bit when you begin drilling. Place the pilot bit inside the
hole, tight against the side, and start drilling on very slow speed until
the body of the saw cuts into the frame to the extent that the pilot bit is
no longer necessary. Remove the pilot bit, and continue drilling your hole
with the saw body only, again using very slow speed. Retrieve the wire with
needle nose pliers or forceps.
