Bosch Jack Breaker 120 -Volt Corded Demolition Hammer

Beast

Owned this for 5 years and have punished it severely. Light weight for its breaking force. Easy to plunge in holes (I dig them) Have had it in pouring rain, in mud, had it running for an hour straight and it won’t quit. Solid purchase.

great jack hammer

I'm a contractor and purchased this a couple years ago to dig in hard soil. Since then I have used it to do all kinds of demo on concrete, tile, brick etc. I stopped renting the Brute as this thing kicks but. Only thing I don't like is it will stick and hammer without hitting the chisel.

quality tool

[This review was collected as part of a promotion.] I said to my wife, "how did i ever get by without a jack hammer! I have 360 acres off grid on top of rock, since I have purchased this I use in continually. I do have a 25kw generator to run it. My neighbors use it on occasion. One has a 48 volt battery bank with a 3600 watt inverter. Sometimes it slow to run. Another neighbor had a small generator and it would not run at all.

Motor runs, hammer doesn't.

The hammer worked great the first time out. Second time we had it on a smaller generator (3000w) and it would run but not hammer. Turning it off and then back on made it hammer for that placement only, as soon as we lifted it, it would stop hammering and not start again when reset. I attributed it to the smaller generator but really that was just a guess. Subsequent attempts with larger generators yielded the same and worsening results. It soon would only run for one "set" when turned off and th...

remarkable tool

best reconditioned tool I ever bought should have bought one a ling time ago

Runs without striking chisel solution

I keep seeing customers complaining about the chisel not being struck while the motor continues to run. I do not own a 11335 however I thinkI have a solution. I have an older Bosch 11305 hammer and it has the same issue when the top of the chisel/spade has no oil on it. Dirt and grime will get gunk up the inside of the sleeve where the chisel is housed. When the chisel moves up and down and it is dirty, the chisel will not enter the sleeve completely. The ram will not hit the chisel ---- so the ...

Awesome medium jackhammer

I'm a general contractor and purchased this jackhammer to demo tile in a bathroom. I had a very old Hilti rotohammer that wasn't doing the job and needed something with more power but not too big. The Bosch 35# hammer was the winning ticket. I bought the chisel bit and went to town. I demoed a whole master bathroom with tile everywhere (walls floors shower) in 2 hours, I had already spent 2 hours with my old Hilti and only got part of a wall in the shower. This breaker was light enough to lift f...

Bosch knows best!

This Jackhammer eases through the toughest of concrete, brick, or block... If I’m nitpicking - The only thing I would like to have seen added to this great tool is some rubber blocks or moulding on the back of the tool, so when it’s rested against a wall or laid down flat on the ground, it would hit the rubber moulding instead of the dura shield housing, which would prolong the life of the tool. (all in all it’s a fantastic tool.)

Bosch is the best

Being in construction there is always a need to break cement most small jobs i would use my Bosch demo hammer but for the bigger jobs i tried to cheat and buy a cheaper brad and it lasted about 1 month until it broke and there service was no help so i decided to just do it right with this one and it’s loke driving a cadallic compared to a beat up car. Works great for all my jobs.

Excellent, Quality Tool

Excellent quality and powerful. Our tool gets abused and keeps running. We only have access to a 5kW genset (with horrible power/voltage fluctuations) and the tools still runs great. Indestructible. Provides years of heavy (daily) service.
