I have an air line plumbed into the air tank on my truck from which I run my chisel and impact, in my shop I have a 5 hp DeVilbus on an 80 gallon tank for all my air needs. I even have a Ingersoll Rand pneumatic overhead chain hoist on a trolley. You can't beat air operated tools for durability, especially if you fork out extra money to get quality tools.



As for air chisels I have two, one with a long 2 inch stroke and the other with half that or less, they each have their uses. For cutting off converters I'm using a 13 amp Milwaukee sawsall, an awesome saw which has a longer stroke than my old Dewalt, the longer stroke utilizes more teeth of the blade and I'm finding not only will the Milwaukee cut faster but also gives better millage on your blades.

I use the sawzall from a 2500 watt pure sine inverter, which is not permanently wired into the truck so I'm able to swap it over to any vehicle in a moments notice.

I'm so impressed with Milwaukee's 5 year warranty and tool performance I recently purchased the Red angle grinder.
