And contrary to popular belief - THIS TOOL HAS AN LED LIGHT!!!!!!! The only thing I do not like about the LED light is the switch. Its an LED and it will not run the battery down if it is depressed by the trigger so I really think this is the only down fall of the tool. Sitting side by side the Milwaukee is bigger and feels sturdier. The Milwaukee is heavier and taller but the overall length is shorter than the Hitachi. The Hitachi has plenty of overmold but the battery does not. The Hitachi has EIGHT power levels though! You cannot ignore that and ultimately feels mor compact than the Milwaukee (not to mention Dewalts 18 and 20v Hammer drills and the Makita BHP454). This is an AWESOME Drill!
