- Bosch Bulldog Xtreme Review and Chiseling Concrete 11255VSR SDS-Plus
This is a review of the Bosch Bulldog Xtreme 1" SDS-Plus Rotary Hammer model 11255VSR. I purchased this tool to chisel concrete and wasn't sure if it would do the job, but it worked great. This 8.0 amp puppy delivers 5800 bpm at 2.0 ft lbs, which is plenty for light chipping work. I demonstrate the tool in action using the Bosch 1.5" x 10" Self Sharpening chisel HS1425 and the Bosch 10" Steel Point Chisel HS1472. Both chisels started out strong, but got dull fairly quickly. Overall, I really like this tool and it comes in handy for a lot more than chiseling. #boschtool

thank you for this demonstration!! definitely getting the bull point for straight up demolition!
The bull point is great for breaking up hard aggregates. In my younger days, a 50 lbs jackhammer and a bull point chisel were the tools of choice to break up concrete slabs. Thanks for leaving a comment!
Thanks for the thorough review. I've got some chiseling to do so I'll have to try this. The Scar Face reference made me laugh.
Thanks for the kind words and for subscribing! For the price, the Bulldog is a handy tool. I’m hoping to do a review of the Milwaukee cordless rotary hammer soon, but it’s too expensive if you won’t be using it often. Thanks for leaving a comment!
If you wanna get that done and not take a week to do it. Drill 1/2 inch holes at corners of your cut out to be made then drill holes between them spaced 2 to 3 inches apart and chisel concrete between holes.
You are absolutely correct! My technique was incorrect and I should not have used this tool like a mini-Jack hammer.
For using the wrong drill bit at the beginning and the wrong technique to break concrete, the drill did pretty good, I was looking for a video like yours, of the drill really working, because I want to buy it, I live in Mexico City and here all the houses are made of concrete, so I need a small drill but with enough power for small jobs, and I'm liking this drill, thanks for the video ✌️
Glad it was helpful. And you are correct that my technique was incorrect. I’m used to bigger hammers. It would have made more sense to use the hammer drill to make holes to the depth I wanted and then chisel it away. Glad the video was helpful. Cheers!
Buy this drill. Its fantastic. Can also use on Toyota spline axle to remove the tough axles
Thanks for the demonstration video . Getting one tomorrow .
For breaking up concrete, I recommend drilling a bunch of holes first before use the scaling chisel or bull point chisel to break it up. Will go much faster. 👍

Thanks dude, I didn't know you needed to use grease. I bought a refurbished one off Amazon for about half off. It was brand new, no manual.
Good find! Glad the video was helpful.
Ah! I’ll try some of that next. Thanks!
For this type of job you better use a small flat chisel. 3/4 " . I use the wide chisel mainly for surface trimming concrete or removing rendering. the point chisel does not work as a well as the small flat chisel in this application as it tends to dig in, making it hard to pull out when it does not break the concrete .
I completely agree! A smaller chisel would also provide more power. Given I needed a depth of 2” to pour concrete, I also could have drilled 2” deep Swiss cheese holes and then chiseled it out, which would have been faster. Thanks for the comment.
Nice review. I purchased this tool for masonry work such as brick and mortar removal. It's light and less than 1/3 the price of a hilti te-30. For serious concrete removal a more powerful tool would be better suited. (Such as an SDS Max or rivet buster)
Glad you enjoyed the review and I agree it’s a good value for what it is. I still use it for chipping mortar and more recently for removing tiles. Works great.
Tool Porm. I just got one from a thrift store. Brand new. Im excited
Ha! Awesome.
i used mine on and off for about 4 hours just chiseling. 2'x2.5' concrete was about 4 inch thick and took a little while to bust up. but this hammer drill did the job. it got hot and noticed the grease liquefying down the bit, but i guess ill start adding some grease next time.
Sounds very similar to my experience! It was a slow process, but it got the job done. You should add grease each time you use the tool or even change bits. I subsequently realized my process in this video could have been better. In hindsight, it would have been faster had I started by drilling with a bit to make 2" deep holes (or a bull point chisel), and then switched to the chisel to carve it out. Live and learn I guess. Thanks for sharing your experience!
I bought that tool this morning at Lowe's and cost me $179 (without tax).
👍 Enjoy! It’s a little work horse.
You need to put grease? When he changed bits, he didn't add grease? I don't think he added grease. Do we just add grease the one time? I was totally unaware of needing to add grease. I've got to look that up. Nice review!! informative.
You should always add grease to the end of a bit before you insert it. If you have this tool, when you first got it you may have noticed it had grease in the collar. The first time you inserted a bit and then removed it, the end of the bit was covered in thick black grease.
Does anyone have experience with that GBH18v-20n? I just picked up one on sale as they are replacing them with the 21n, I saw some mixed reviews and wanted opinions.
How come you don’t do a video with the hammer drill taking out tiles from the wall
Great question! Perhaps I’ll have to add one. I’ve only done one tile job with this tool and it worked well. I would have recorded it, but one way to make any ob take 3 times as long to complete is to make a video about it. 😃 Thanks for commenting!
I would have drilled holes every three-four inches to help it disintegrate OR use a bigger tool.
You are absolutely correct!
Sorry, how I can change the handle I mean, i move it a way and now, I can't put it back because de hole is smaller and I want to know how to make it bigger in order to fit it, as at the original position
If you’re asking how to reposition the auxiliary handle, loosen the handgrip by turning it counter clockwise, reposition the handle by sliding it where you want it, and then tighten the hand grip by turning it clockwise to lock it in place.
Any other options for grease besides the brand name one? Thanks
Any lithium grease works fine.
How long did that take ...?
The 2’x2’ section took just under an hour to do although I’ve found that if I want a project to take twice as long, I make a video about it. 😃 Had I used my Milwaukee M18 cordless SDS-Max rotary hammer, the job would have taken 15 minutes. Unfortunately, the Milwaukee tool is not a budget friendly tool. I choose to use the Bulldog because I couldn’t find any chiseling videos of the product at the time and I thought it would be helpful. Thanks for asking!
I broke the handle to mine. Where can I order the handle?
Contact Bosch customer service.
Great video but the constant dinging with the thumbs up is nerve wracking.
Thanks for that feedback! I try to make the noises subtle, but sometimes I don't get the volume adjusted properly.
This demonstration was not great. I can't tell if its your 1st time using a rotary hammer or if the tool is awful. I just bought the same bulldog so I'll have to try it out.
Thank you for the feedback! I always appreciate it when folks leave comments in order to improve videos. If there is something specifically I could have done better, please let me know. I also recognize that nothing beats experiencing a tool in person, which is why I appreciate Bosch’s “try it and if you don’t like it, return it policy.”
Also, the demo was the first time I’ve used this compact tool, but definitely not the first time I’ve used a rotary hammer. I would have preferred to use my Milwaukee 1 3/4” SDS-Max hammer, but I wanted to demonstrate a more affordable option. Thanks again!
@@BruceAlanR I saw what he was saying, but I do appreciate you taking the time to make the video and sharing your work. So thank you. the above comment was probably about your form. You seem to be a bit dainty with it and using your arms to support the tool from while you stand way away from it. You're fighting it instead of letting it's weight help you. The cord still being wrapped and maybe on your shoulder is just another thing to juggle and fight with. Use a SDS drill to perforate the concrete to depth, then break it out with a chisel. That's what I would do anyway. I've spent time on a jackhammer though, not a rotary hammer. Your use seems to be just a baby jackhammer, point it down and keep it balanced on the chisel, you shouldn't be putting effort into supporting the weight of the tool, the chisel will hold the tool up. If anything you could have some weight on it but listen to make sure you're not bogging it down. Standing back like that will wear you out, doesn't matter if it's a 6 lb rotary hammer or a 60lb jackhmmer. Standing bent over like that and fighting that vibration to hold the hammer up is especially hard on your back too. First day the jackhammer kicked my 5'6" 140lb 18 year old butt in about 15 minutes, older guy came over and asked if I wanted some advice. He stood the hammer up straight, and told me to drive it like I was riding pogo stick and put weight on it until it started digging. I had been using the jackhammer like you were using that rotary hammer leaving chips but not digging. After he left I had to get him to help me pull it out of the hole through an 8" pad because it just melted through and buried itself before I knew what was happening.
Thanks for the comment! You are absolutely right! The Bulldog was new to me and perforating to depth would have made for much easier work. I was using it like I was removing tile instead of breaking concrete. Years ago, when I did paving and concrete construction, I had to learn to use the 50 lbs jackhammer connected to a compressor and balance it upright to break up concrete slabs. Hard work! The Bulldog is so manageable given its weight that I overlooked that the tool should be allowed to do the heavy lifting. Thanks again!
This tool is too small for this job smh.
I agree!
Well I'm not impressed,Nothing different than any other SDS drill
Fair enough.
