BOSCH (S-B Powertools) 11241EVS description
A combination hammer is probably the most expensive tool you'll buy for the job site, and with this Bosch, you know you're getting top performance for your money. This model is enormously efficient, powerful and versatile, turning stubborn tile into rubble and drilling effortlessly into 3-inch thick concrete.
Part of the beauty of this combination hammer is that it actually doesn't want you to do the work for it; we found that exerting force on it actually slows you down. Instead, firm, steady pressure got us the best results.
First, the features: Bit changes couldn't be faster or easier, to the credit of the SDS-max bit system. Just twist the bit and push it in until it locks into place automatically, and you're ready to work. Set the selector lever to one of three clearly marked positions: hammer only, if you're chipping or demolishing; rotary hammer for drilling; or the 0 (horizontal) setting to use the great vario-lock feature, an ingenious setting that lets you position your spade or gouge at exactly the attitude you need. While in the vario-lock setting, you just rotate the locking sleeve to one of 12 positions at 30-degree increments, then switch the selector back to hammer mode. An easy twist of the locking sleeve secures the bit in position. And when you're in hammer-only mode, the tool automatically boosts power by 20 percent for maximum chiseling.
Maximum speed is controlled by the Auto-Max® dial on the tool body, just above the service reminder and power indicator lights, another top-of-the-line Bosch feature we love. The Service Minder light illuminates when it's time for preventative maintenance, and the beautiful Bosch design lets technicians quickly replace your brushes or power cord and get your tool back in your hands as fast as possible.
Aside from its incredible power, the feature that stands out for us is the ergonomics Bosch is famous for. They've been working on it since the 1950s, decades before most of us even heard the word. In this tool, you'll notice the distinct reduction of vibration, the lion's share of it absorbed by the tool's handle, not your arm. The auxiliary handle swivels a full 360 degrees, so you're never straining and risking injury at an awkward work angle.
We rarely find a tool that we can't tack a wish list of changes onto, and this is definitely one of them. It's the quality, power, comfort and dependability Bosch is deservedly known for. -- Kris Jensen-Van Heste

BOSCH (S-B Powertools) 11241EVS reviews
Rugged, reliable and very high quality
helpful for 9 of 9 people
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!
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.
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.
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.

Good Investment
helpful for 6 of 6 people
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.

A VERY nice 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!
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!
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.

Bosch Combo Hammer
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.

rotohammers for the real user
what the heck is a foot pound anyway? i did a lot of research trying to figure out the answer to that question and came up emptyhanded. i called milwaukee (i own 12 milwaukee tools) and the guy i spoke with wasn't entirely helpful. i called bosch (i also like bosch and their rotohammers are well known for reliability and cost effective) and asked what a foot pound was and i got some answer like "it's the measure of how many pounds of force are applied to each impact." no mention of the foot in the equation. it also doesn't make sense to me because 10 pounds of force isn't very much, yet 10 foot pounds is enough to break apart a 3" slab of concrete. perhaps it's the repetition 10 pounds of impact several hundred times a minute that matters? does this mean that a tool with 5 pounds of impact force with twice the speed of a 10ft/lb impact will do the same job in the same time? i couldn't tell you. i know that a .44 magnum produces about 1,000 foot pounds of force and a good bosch jackhammer produces about 40 foot pounds of force. so a rotohammer like this is clearly a lesser tool, but what can it do in the real world? i took out a 9x12x36 inch thick concrete step with this thing, but not by chipping away at it bit by bit. i used a 5/8" drill bit and drilled four holes in a row and then connected the dots with a 3" chisel. broke into managable pieces within about 15 minutes.
my philosophy is to spend more and get a tool that you won't regret buying. with rotohammers that philosophy means it's better to pay more and get something with more power - it'll make the job easier and it means you'll be able to do a wider range of jobs. taking out that step is probably the biggest solid piece of concrete i'll ever be chipping at so i think that this rotohammer is sufficient for the diy-er and most pros. it'll take out stucco without much trouble (though it'll probably be too heavy to hold horizontally for long) and it can go through the foundation for those 5/8" earthquake retrofit bolts you need to put in. it should be plenty powerful to drive a grounding rod with the proper attachment. haven't used a spade to dig in hard clay, but i think it would do a good job there as well.
i've used the bosch bulldog and a couple hilti rotohammers, including the te35. these are lesser models in terms of power. the 11241 blows them out of the water, but it's not a fair comparison. unfortunately i haven't tried the competition in this price range.
the trigger lock engages only in hammer-only mode, not in drill/hammer mode, which is too bad. other than that i haven't found any issues with it ergonomically or any other way.

Bosch Hammer Drill
This drill works fantastic. I am able to drill a 3/4" x 6" hole in granite in about a minute. I also use a chisel bit to face the stone with that works great also.

awesome
This Hammer drill is very powerful. Hammer-only function is great for chiseling. Excellent tool for concrete work and drilling.

Great tool for medium duty applications
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
