"The Bulldog and a 1/2 inch x 18" drill bit made it easy to perforate the cement and allowing for a swing of a sledge hammer to break it up into manageable junks. I think the largest SDS Plus drill bit I can get for this Bulldog is 1 1/4 inch."
"Metal depth stop as opposed to some vendor's plastic ones, rugged case, plenty of power cord, easy controls, aux handle that can be swiveled to any angle around the nose of the tool, or removed entirely."
"It ended up being a lot more work then I thought it would be to chip away the tile and then chip away the thin set."
"I got a couple of holes drilled eventually (after minutes of noise and effort), but there was one hole that ran into a rock in the concrete and the Ryobe couldn't get past it and I eventually gave up. I have the SDS-plus bits, but I also got the drill chuck and did the holes for the threshold with TapCon bits, since those were the screws I was using."
"I told my client I'd be back next week and went home and ordered the Bosch 11255VSR Bulldog Xtreme from Amazon. Sure enough, the Bulldog punched the holes into that rock like the proverbial hot knife through butter."
"ft. in about 2 days time with the aid of a shovel once we used the tool to get underneath the tile."

Becareful when using it is very easy especially after you tire to rest tool against leg blocking air cool intake heating motor up fast. Anyway for you Union guys that will bark at me for getting this (I have spent thousands over the years buying american when possible) this hammer does what the $900 hammers do."
"This is equal in performance with any similar demo hammer that is electrically powered. Make no mistake however, this is NOT a 90 lb pneumatic breaker/jackhammer with a 4" chisel tip. All you need to do is aim the point, and pull the trigger, letting the tool do the work. The tool itself is not that noisy, but the tip impacting the concrete generated a sharp noise that was loud enough to clearly hear 50 yards away. I found the bull point much more efficient at splitting the concrete than the flat chisel. Even though this tool is almost 35 lbs, you can guide it to roughly shape concrete into a radius, especially with the flat chisel tip. You will not be able to continuously use this on a 15 amp circuit with a 200 foot lamp cord. You may get away with very light, intermittent use on a 15 amp circuit with at least a 12 gauge extension cord, but eventually the circuit will overheat, and trip the breaker."
"This hammer with attachments can’t be beat. We have more to go, and I am so glad I spent the money on purchasing this hammer, instead of renting one."
"If I were to rent a jack hammer at $35-$60 per day, this will pay for itself after doing a few more fence posts."
"i've used higher end brands before and they tend to have a nicer finish and less sharp edges and overall nicer looking."
