Coming from mainly using a Bosch Bulldog with SDS-plus, this hammer is a massive step up in power and material removal, when it's required. This particular hammer is a bit heavy, but just light and nimble enough that it can be used for good periods of time, and fairly precisely. I've used this for at least 10+ hours of actual runtime now, and I can't come up with many negatives. I can't see many people needing this for "home use", versus professional, but go for if you can get your money out of it, etc..
Overall build quality is great, as expected. Unless it ever changes, this unit is made in Germany. The case is large and adequate for a hard case. The straight handle that is featured on this unit is more ideal for drilling compared to the hammer only model's handle, but I have only used it for demolition and it does fine.
The trigger stays on during hammer-only use, and motor speed can be adjusted. This is nice compared to holding a trigger for long periods and the motor speed is very useful for all of the potentially endless applications. Sometimes too much speed results in bouncing off/out of concrete, brick or other materials, and a lower speed works better. Not to mention the speed adjustment is necessary for many drilling applications.
The anti-vibration features work very well. You feel so little compared to how much work is being done. Regarding vibration, compared to say the smaller units (Bulldog) which don't have anti-vibration, this unit is actually less fatiguing.
The SDS system of course works great, SDS max bits are much larger than SDS plus bits.
Overall I'm happy with this unit. It is high quality, powerful and works very well.
As with many homeowners, I have occasional need for a hammer drill-type tool, and have happily rented one for $50 a day as required. Lately, I had a three week project that involved concrete chiseling, asphalt cutting, rebar driving, concrete and cinder block drilling, and tamping of crushed limestone and cold-patch asphalt. Let's see, $50 x 3 x 7 = $1050 = "too much", time to buy the tool that can do all this, assuming it can be had for less than the rental.
After much Googling, reading reviews in tool magazines, talking with tech support at companies such as Bosch, Milwaukee, etc; I decided that what I needed was a tool that primarily is a light weight version of a jackhammer, with the ability to also rotate a cutting bit whilst hammering for certain chores. The solution meant that I needed a rotary hammer, not a hammer drill (former always hammers, but can also turn, latter always turns, but can also hammer...got that?).
Next step was to decide on how big a rotary hammer was needed, and 1-5/8" seemed best after consulting experts. Variable speed was also desirable, as was "SDS-Max" chuck, as apposed to the older spline type chuck; all manufacturers said that spline is dead or dying, and SDS-Max is the new standard, and most bits in the future will be available in this style.
The Bosch model 11264EVS was the closest match, at least in a high quality brand (no Harbor Freight Chinese tools for my shop, not anymore, thanks). Bosch make an otherwise identical rotary hammer that takes the spline bits instead, by the way. The EVS suffix means that it has the variable speed function, but for a few $ less they have one without the EVS.
The SDS-Max is a spring loaded chuck for one-handed tool insertion and removal. Pull back the chuck ring with one hand while holding the hammer with the other hand, and it stays in this 'cocked' position. Simply insert the shaft of the SDS-Max style bit into the chuck, and when the end of the bit reaches the rear of the chuck, the chuck internally snaps closed on it, locking the bit to the tool. To remove the bit, pull back the ring and the bit practically falls out by itself.
The hammer has two indicating lamps; one shows power is on (cord plugged in to power source), and the other lights up when the tool needs service, which is usually when the bearings have worn out. Bosch has a service for replacing these when the go, which is not for a long time; unless you use this every day professionally, you will probably never see this light turned on.
The hammer has two triggers; the top one starts the motor when in hammer-only mode, and acts like the variable speed trigger on a regular electric drill when on rotary hammer mode. The bottom trigger stops the motor when in hammer-only mode. To clarify, in drill (rotary hammer) mode, you squeeze and hold the top trigger, and the amount you squeeze it determines the speed, and in hammer-only mode, any amount of squeeze of the top trigger locks the motor in 'on' at a fixed speed, no need to hold the trigger, and the lower trigger turns the tool off.
There is also a variable speed knob which is used to set the maximum speed the tool can reach when the trigger is fully pressed in (in rotary hammer mode only).
On the top of the hammer if a large knob to select the mode. One position is for rotary hammer mode, the middle position unlocks the chuck's rotation, and the third position is for hammer-only mode. You use the middle position to decide which angle you want the bit locked to when in hammer-only mode (where the hammer is not rotating the bit). There are 12 detents that you can rotate the bit to when the knob is in the middle position, and returning the know to hammer-only position locks the bit in that position.
The hammer has two handles; a fixed handle with anti-vibration shock absorber, and a secondary handle near the chuck. By twisting the secondary handle's grip, it is unlocked and can then be rotated anywhere around the chuck, left, right, up, down, or in between.
Hammer construction seems to be almost all metal with plastic trim and outer housing as required to make it double-insulated. Grips are rubberized.
The hammer itself is pretty quiet, with most noise being made by whatever bit you are using impacting whatever you are using it on.
I bought the concrete chisel, the asphalt cutter chisel, the tamping plate and its rod bit, and the ground rod hammer bit (which I use for sinking rebar deep into the ground). Each of these is priced at about $50, so they add about $200 to the price of the hammer. The hammer comes in a large case made of tough plastic. The case has compartments to hold a tube of oil (which comes with it) and several bits, including large once like the tamping plate and the asphalt cutter; you can probably fit most bits in the case along with the tool itself.
The hammer takes almost 15 amps, so make sure you have a heavy duty extension cord and an outlet on a circuit that is not also running something heavy like a fridge, air conditioner, etc.
This is a first rate quality tool, and you pay for that quality. I am quite pleased with mine.
I purchased this on August 20, 2017. I waited a little bit to give me a chance to use the drill. So far I've used it to drill 1" holes in brick, block and concrete. I used the attachment for driving ground rods. Most recently I used a chisel bit to break up some concrete. It has worked extremely well so far. I will definitely update this post if anything changes.
I bought this tool to remove a entire house of old tile. I have both the SDS plus and the SDS max by Bosch. And neither has ever disappointed before. It pulls up tile faster than you can discard them. IT's also very useful to chip away thinset if you have the right angle on it.
I love this tool. For light demo work, it's perfect. I chipped the daylights out of some craters in my concrete pad during some repairs and it worked quickly and without beating me up too much. As a drill it's a champ and eats right through walls and floors. The Bosch name makes me think I won't have to worry about durability, but I haven't worked it that hard yet, so time will tell. If you need something for heavy drilling and light demo work, you won't be disappointed by investing in this heavy-duty combi-hammer.

Wow, I am impressed with this Hammer Drill. With the Spade accessory, I was able to easily loosen up consolidated soil under my house for sewer line repair. Dug trenches thru solid and compacted soil without too much effort. Lot easier than using a shovel and pick in tight space. Jack hammering old fence post concrete was easier than my 45lb Makita jackhanmmer, half the weight and lot less vibration. Can't wait to find reason to use it to drilling into rocks.
Excellent drill, love the new features!! Started driving ground rods, works nice. Looking forward to other uses. Fortunately I have always had good success with bosch!! Maybe alittle high price, but worth it if it will last!!
So far I have used this tool (Bosch 11264EVS) to dig hardpan, drill concrete and break concrete. It has done an excellent job in all capacities and is light weight enough to run all day.
The vibration dampening system works great! I have used a lot of older rotary hammers and they can beat up your hands and elbows after a while, this thing is pretty smooth for what it is.
***One note: Bosch has ditched the one handed bit change feature, apparently it was prone to sticking. Do not expect to see it on your tool when it arrives, even though it is still shown here in the picture and covered in the description. If you are used to standard SDS Max chucks, that is what you will get so no worries.
This is a serious tool! Pounded out several window openings and a full bath as well as a laundry in a house built in the late 1800's. Those in the know know concrete only hardens with age.
we have 4 of these. PLEASE keep making them in Germany. They are awesome for the money!
