I had previously reviewed the Impact driver after purchasing it, only to return it so I could buy this combo kit for not much more money. I was more than intrigued by the only subcompact hammer-drill on the market and it does not disappoint. I already knew that the Impact Driver was incredible and have written a review on the quality and durability of it in which I detailed a test that I put it through. I will admit that I got a better deal from Home Depot for this combo than I could find here on amazon, but that shouldn't detract from this review at all.
I was like a little kid when I got this kit home and immediately charged up the batteries so I could try out the hammer-drill. After charging, I placed various Bosch hammer-drill bits in the chuck and went to town on brick and ciderblock. To say that I was impressed would be the understatement of the year. This thing rocks!!! I don't know why I waffled so long before purchasing this drill. It makes drilling masonry so much easier and even kind of fun. It is so lightweight that it is like a dream for your hand. I drove about 20 tapcons of various length through scrap brick and cinderblock without a hiccup. Even after doing this the battery level indicator still showed a full charge on my battery.
I was amazed and really couldn't be happier with this tool. I know some people will complain about this not coming with the blow-molded case, but the bag is very strong and durable. You also can fit more things in here like; other m12 tools, accessories, spare batteries and whatever else you wanted. And to those idiots who complain about the chuck loosening...after you tighten it with the trigger, you need to use your hand and manually tighten it a little bit more until it clicks. It is a very audible click and then your bits will not slip from the chuck due to loosening. An amazing buy and will look into more m12 tools and will be getting the XC batteries as well. These batteries are by no means bad, but XC batteries double runtime easily and balance the tool better. Thanks...Ray.
