Summary: unless u need a full time rotary hammer,this hammer drill does the task for less and offers more functionality - drills/hammers concrete/cement; drills and drives wood/metal screws and its also useful for everyday household use.
Summary: Chose this drill because of the positive features it delivered. The power draw on batteries is greatly reduced with brushless motor technology this results in longer battery life. The weight of the drill is not too great allowing use for extended periods without physical strain. And it is pretty nice to have user option on whether to use the drill light or not use it. When used it does deliver a pretty good discharge of light illumination a large area.
Summary: Talk about torque. I had to repair an old door frame that kept getting lose on the hinges. I used 4" screws to ensure that the hinges would never get loose again. I was amazed at the power of this drill. It showed no effort at all using these long screws to go through 3 layers of wood. The rubberized handle helps you handle the power that this drill has. Not too heavy either. This is by far the best cordless drill I have ever owned and I have had a few over the years.
Summary: This hammer drill is an addition to my collection of Hitachi drill/drivers. I purchased it based on the performance and warranty of the other purchases I made in the past, and am most happy with the fact that I know have many Hitachi tools and all the batteries are interchangeable. This is a very important thing for me!
