HF sells a hydraulic punch/driver set that can be had for ~$70 or so on
sale / coupon. You still need to drill a pilot hole for the punch driver
and can use clay, magnets or a shop vac to catch chips from that, but
after that you can punch nice clean holes up through 2"+ size with ease.
I've used the $800+ Greenlee hydraulic punch drivers and the HF one
works just as well.

Pete, which HF item number are you referring to? I will definitely get
it.
