The Greenlee punch from Home Depot is for punching 3/4" electrical conduit holes. The hole size it punches is 28.2mm diameter which is perfect for control panel punching. You get what you pay for here. The reason Greenlee is so expensive is because of the thickness of the metal you are punching through. These are high quality punches and worth every penny.

Some local tool rental stores can rent you the punch for $10 a day if you don't want to buy it.

Remember that to keep the punch sharp and cut through the metal fast and easy you spray the hell out of both halves of the punch & die with WD-40. This is one of the rare times that WD-40 is actually good for something and is recommended.

Also keep in mind that you need a 3/4" hole in the metal in the first place - that hole saw will set you back about $10.  Note that a 1-1/8" bi-metal hole saw is only $14.
