mill sq. hole for meter
Aug 23, 2020· I have several square Greenlee punches, but the largest is 1" so it would take four wacks to make this hole. I have done it that way, but an alternate method is to use a 1/8" end mill and run past the corners by 1/16". The bezel on most electrical meters will cover that much. As far as renting a square punch at a local rental place, GOOD LUCK.
