‘Couple years back I added a Husky 1/2” air impact to the box, it claimed 600 ft pounds. It is way more impressive than my other older,air impacts. I need to do some tests, but my cordless 1/2” DeWalt impact gets down and does work. Used to be my corded 1/2” Milwaukee was the tool when the older air powered impacts couldn’t get it done…not so sure anymore. I love tools and have 6 or so impacts of various corded, cordless, and air power.
‘’When I built the shop I ran 3/4” pex in the wall to my 8- gallon air compressor. No complaints.
