I have been using the Bosch 11241EVS 1-9/16-Inch 11-Amp SDS-Max Combination Hammer for three years. No problems. It was a great investment because I would have had to rent a similar product at least 20 times over that period. I have used it to dig footings and trenches in the local hard-pan clay; drill into concrete slabs; break and remove concrete sidewalks; and, break out mortered stone walls. I use the clay spade, and a variety of SDS-MAX bull-points, chisels, and drills. I highly recommend it.

I have had my Bosch 11241EVS for about three months now. I got tired of renting a hammer for about $80 a day plus the time/gas required for turn around at the rental agency. This Bosch combo hammer was paid for after only 6 days use. Sweet!

br /I have used it to cut 1 1/4" and 1 1/2" holes through 3" cured floors, chopped a number of 8"x16" concrete beams that needed to be trimmed 4", chopped beam pockets, chopped out many 4" deep rectangular holes for receptacle boxes that the tilt up guys forgot to cast in place and cut many holes for the electricians. This tool has never given me a moment of problem. It has performed perfectly. Vibration and noise is reasonable, soft start up is a big safety plus, the big SDS Max chuck releases instantly at all times. The balance and ergonomic design of the handles is first rate. Working with a chisel chops out cured concrete as easily as if you were removing hard wood. The many blows per minute multiplies the power of this machine dramatically. Working in the hammer mode increases power about 20% and I assure you, it makes quick work of demolishing, chopping or drilling most anything. SDS Max drills and core bits are very popular, have a tremendous selection. The SDS Max design is extremely rugged and easy to engage or disengage.

br /The only criticism I have concerns the 'on' lock button which can be in the depressed position so that when the power cable is first plugged in, the tool starts. (You must apply pressure to the bit or core before it actually hammers.) I just make sure it is definitely not depressed.
br /
br /This machine does big work, is not too heavy (saves my back!), and in its carrying case, fits nicely in my truck. It has saved my bacon many times and it has earned my gratitude. I am extremely satisfied with this tool and recommend it for consideration to anyone who wants a high quality combination hammer with power.

This is a great tool for digging through tough soil. I can dig a trench with it in no time.
br /
br /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)
br /
br /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

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.

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!
br /
br /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.
br /
br /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.
br /
br /I would definitely recommend this tool!

Do yourself a favor, invest in this hammer, you will be glad you did! It is designed and built to last. The BEST of the BEST! Performance is outstanding.

I couldn't be happier. Bosch has never let me down--Great tool, Great Company!! I have nothing but praise for Bosch power tools. If your in the market for this tool ,look no more!
