  • ONE OF THE BEST POWER TOOLS I OWN!
Style: 11255VSR
(Review for "Bosch 11255VSR BULLDOG Xtreme 1-Inch SDS-plus D-Handle Rotary Hammer", Purchased on Amazon June 2013.) 2-1/2 years later this tool has held up to the test of time, durability, and performance (and abuse!). It has so far easily chiseled through 600sqft of floor tile and thinset laid over concrete slab, broken apart portions of 4" concrete slab (after drilling holes into it first), and drilled many dozens of vertical holes into existing reinforced concrete foundation wall, ranging from 5/8" to 3/4" diameter holes down to 8" to 12" deep. As expected it has no problem with all of the various SDS-Plus bits and attachments, of which I have 6 different SDS-Plus concrete drilling bits, each 18" long, and 3 different chisel bits. The tool often gets covered in concrete dust after drilling yet does not impact performance and quick blast from an air compressors will easily clear the dust. I am impressed with its longterm durability, especially after weeks or sometimes months of no use while sitting in my toolboxes - it's been stored in my S.Texas garage or truck toolbox, exposed to S.Texas summer heat and humidity (but I've never allowed it to be directly exposed to wind-driven dirt, or to rain/water). I rarely use the case. [The case it ships with is terrific for storing the tool with its D-Handle and almost a dozen SDS-Plus bits (depending on length and tip), but it occupies too much space for my needs, and so it is stored in a mobile toolbox along with other power tools. The case is sturdy, of durable plastic, with good locking latches - I believe the case over time will not crack or become brittle as the plastic material appears to be the same as for other cases from Bosch, Dewalt, etc.] The metal bracket on the handle comes in extremely handy - pull the metal bracket out and the tool can be easily hung on any horizontal pipe, scaffold member, etc. - just like the Bosch Nail Guns. The tool's settings for forward-reverse (a slide switch) and for drill-combo-hammer (a dial) stays in place, and after more than a 100+ hours of (intermittent) use over 2-1/2 years, the dial and slide switch settings have never vibrated out of setting, unlike some other lesser (non-SDS) rotary hammers I've had. I have found that the reverse setting (counterclockwise rotation) is just as powerful as the forward (clockwise) rotation both in terms of speed and torque - an 18" long 3/4" diameter SDS-Plus drill bit will often get stuck on it's way to 8" to 12" deep, especially when it encounters rebar or some really hard stone aggregate...and as the tool description says, it disengages the torque when it detects the bit is stuck. Getting unstuck is as easy as throwing the hammer/drill into reverse. It almost instantly gets unstuck, ready to go at it again. The large red trigger (on/off) button on the handle has so far been great - I can fit 1-2 fingers to hold it down for those long drills into concrete (I have not complaints on the trigger-pull as I do on one of my handguns :)). The best part is that this trigger appears to accurately and proportionately control the variable speed rotation of the drill (in either forward or reverse) - you can go from zero to full speed rotation fast or control the drill/hammer speed as precisely as needed, which is fantastic when first starting off a drill bit. In my opinion, this SDS-Plus hammer-drill is powerful - with the right SDS-Plus concrete drill bit, most of the 8" to 12" deep holes in concrete take only several minutes. (IF you need a more powerful hammer-drill for concrete and hard stone, well...get the bigger cousin.) Bit changing is fantastic with the SDS-Plus format and the tool's quick-change chuck - the chuck is a solid design. Once the SDS-Plus bit is locked in, it doesn't come off or come loose, and the only times that it does is because the bit wasn't properly/fully inserted. The D-Handle is in my opinion adequately designed and does the job well - I've never removed it, always using the D-Handle on every use without a problem whatsoever. The only issue I have had is the depth gauge, but nothing worth dinging any stars from the core tool itself...whatever metal it's made of (aluminum?) is flimsy and it bends way too easily. Sure I can unbend it but it's a bother trying to really straighten it out. It is also short for my needs, although I think most users will be happy with it. [FYI - 18" long SDS-Plus drill bits have 4-6" of empty shank and the depth gauge is barely long enough when drilling down to only 6"-8". I have no comparisons to other hammer-drills of the SDS-Plus class so I do not have adequate perspective to share. I bought the tool based on the reviews on Amazon and research of SDS, SDS-Plus, and SDS-Max hammer drills. Even with my own [limited] abuse, I think this is one of the best quality, most powerful and most durable power tools I will ever own. In a few weeks, I'll be using this tool to pound 5/8" and 3/4" by 8 foot long ground rods into rocky soil...I have no hesitation that it'll do a great job fast. ... show more

  • Great simple product
Style: 11255VSR
This Bosch Drill is just the ticket. I'm a retired home owner, so I might drill two holes this month and 200 next. So far I punched about 50 holes in 8", 3000 psi concrete and it has performed flawlessly. The last one I had ( some jap brand) lasted 3 holes and burned up. When I was working we had the same drill and probably used it for a couple of years without any problems. For the value, excellent, great quality. easy to use. Not super lightweight, but for a hammer drill, you dot want that. ... show more

  • What a work horse this hammer drill turned out to be !
Style: 11255VSR
Why did you pick this product vs others?: We had to remove a bunch of ceramic tile ( hundreds of square feet) from a cement floor after a water disaster. This hammer drill made the job easier. Much of the tile came up in sheets, others took more effort to get separated from the thin set. The dust was everywhere and I hope we never have to do a job like that again. We didn’t use it to get all of the thin set up, a contractor finally took care of that issue. We wouldn’t have been able to do what we did without this machine. ... show more

  • Removes Chattahoochee Rock!
Style: 11255VSR
We have a stamped concrete patio that the previous owners had covered with Chattahoochee Rock. (Don't EVER do this by the way! You will regret it and will have to chisel it all up someday when you realize how wretched the stuff is!) My husband and I have contemplated how to get rid of this stuff for a few years. We think about it, then decide to revisit the issue "next year", mainly because there is no way to get it up that doesn't cost a lot of money and might ruin the concrete underneath in the process. We got an estimate from a contractor who said it would be at least $1000 to remove it, and no guarantee that the concrete would be in decent condition underneath. We decided to wait a bit more while I researched it. There really isn't a lot of discussion about removing Chattahoochee online. I found a few posts, but there was a lot of disagreement as to how to go about it. I went to a rental place that said I'd need to rent a jackhammer with a tile blade, and that would be $75 a day. I figured this was a job that would take a few days, so I hesitated. I came to Amazon and searched for a tool similar to the one that the rental place had suggested. I found this Bosch 11255VSR BULLDOG Xtreme 1-Inch SDS-plus D-Handle Rotary Hammer. One of the reviewers had used it on Chattahoochee Rock! (Thanks for your review--it was so helpful!) We ordered the tool, and a wider blade (though you are limited to how wide a blade you can get for this model--we ordered this one: Bosch HS1425 SDS-plus Shank Hammer Steel - 1-1/2-Inch x 10-Inch Wide Chisel Self-sharpening--you can get it here.) When it came we tried it out. Let me just say that it was amazing! It took a few tries to get exactly the right angle for the chisel blade, but after that it was smooth sailing. We let the hammer rest for awhile every 15 minutes or so (we needed to rest too!) but all of the stone was removed in a few sessions over a few days. (It's HOT here in south Florida so we couldn't do it all in one day). The patio is about 400 square feet. We used gloves and eye goggles, as it does kick up some of the rock. I wish I had taken some video so you could see how easy the rock came off. There were some spots that were a bit harder, but it all eventually came up. I have a couple of pictures taken during the process--I'll post them here. My husband and I think this hammer was the best investment we've made in a while. I can think of so many future uses for it--removing tile or vinyl flooring, removing tile from the tub and shower enclosures when ready to remodel, etc. Just remember to let the hammer rest now and then to keep it from overheating. As a bonus, the stamped concrete underneath survived the whole process and after a coat of concrete sealer looks brand new! ... show more
