This is Part of Milwaukee's new line of impact wrenches which is a significant upgrade over the previous ones. They're a bit smaller and weigh less but provide more nut-busting torque than before. Another key upgrade is the front LED lights which help when working in darker areas and also has a 4-MODE Drive Control which allows you to regulate the speed and IPM's. The 4th mode is an auto-shutoff mode which is used for hand tightening applications and auto stops. If you are buying the high torque, consider adding the Milwaukee High Torque Impact Wrench Protective Boot to protect your gun.
