Battery powered impact guns, ratchets, die grinders, and drills are getting more and more popular as the battery life is getting longer and more powerful tools are coming on the market everyday.
Ingersoll Rand makes a series of wireless battery powered tools called the IQv Series which are quite impressive looking. The torque on the 1/2 inch drive impact gun is 360ft-lbs which is really good for a battery powered tool and weigh’s at only 6.2lbs. I like that fact that battery powered tools are so handy when working on a car as you don’t have to worry about the air line getting in the way of things.
