These hole-punches are a lifesaver.
They pay for themselves with their first use.
Make sure you use cutting-oil and regular oil on the threads, to keep them sharp.

A half-dozen turns and the piece snaps out, leaving a perfect, finished hole.

Holes for the mounting bolts are also marked and drilled.
Really nothing should be mounted until the transformers are drilled and bolted on,
but its hard to resist the fun of pre-assembly and a first look:
