Item : B0000695HF Customer Reviews awesome by .. T. Crump (Texas) This Hammer drill is very powerful. Hammer-only function is great for chiseling. Excellent tool for concrete work and drilling. Great Tool! by .. Brian Johnson () So far I've used it to remove a section of patio tile, break out a 3" concrete slab and core a 3" hole through a concrete footing and all I can say is...wow! Bosch makes great tools and this one is no exception. Great power with some fantastic features...the shock absorber added to the handle really works, much easier on the hands. Expensive, yes, but if you work with concrete you'll be glad you bought it. A VERY nice tool! by .. S. argyros (Tuckahoe, New York USA) I bought this hammer to remove old deck posting. The people that had done the original deck, to their wisdom, instead of using a frame mold and pouring concrete, they simply placed a bunch of bricks and rocks around the post, dug a big hole, and fill it with concrete! The slab was huge! This tool went through it like it was butter! I was able in an hours time to break up the old post into chips, which then allowed me to easily remove the posts, and do the job right. Very comfortable to use, and pretty straight forward. Seems to be build well, and I am sure this will last for a few years. Manual says the brushes are good for about 300-400 hours, at which point you need to send the tool back to Bosch for replacement brushes and lubrication. So if you are going to use this one a lot, take this into consideration, since shipping it I am sure will be a small fortune due to the weight. I would definitely recommend this tool! Great tool for medium duty applications by .. B. Card (New Mexico) This is a great tool for digging through tough soil. I can dig a trench with it in no time. One word of caution: Don't buy a big clay spade for digging with this tool because it will not be able to handle it (not enough power). I got the dewalt flat head spade and that works great (after my hitachi spade was too big to dig effectively) This tool is comfortable to use and works good on concrete as well. I highly recommend this to anyone who does not want to hand dig anything anymore Bosch Combo Hammer by .. G. Walker (california) This tool is priceless. Lightweight and easy to use. This tool saves me time and my back. The bits are easy to change. I have used this tool for trenching with the shovel attachment. What a time saver. I would highly recommend this tool.
