Some interesting replies so far. You want a corded SDS drill to remove the tile. Like mentioned it is a 2 step process. Chip out and remove the tile and then clean up the thinset. Depending on the quality of the tile job the thinset removal is usually the hardest part. After you rent or buy a decent sized rotary hammer drill get a tile removal bit, they are a 2" wide angled chisel. Chip out all the tiles. Some come out easy in full pieces. Some come up in 1"x1" pieces. Once the tile is out then rent a 6" flat chisel like this, http://www.zoro.com/bosch-scraper-f...AcE5CdRadtRZdhUSZdAbqBoCPN3w_wcB&gclsrc=aw.ds. It will get the thinset off and not tear up the concrete. Anymore questions just ask, I've tore out thousands of sq ft of tile and thinset.
Also those recommending a multi tool have never tore out much tile. I'd pay money to watch them try to tear out a 1000 sq ft of tile on concrete floor with a multi tool.
They should carry that chisel at Home Depot, right? I looked at our local farm store and no luck.
Signcrafter knows what he is talking about. I have also done probably 10s of thousands of feet of removal myself and own all of the tools needed (sds max hammer, tile remover bit, scraper). What you have in your picture with the hammer/chisel is about 3 seconds worth of work with an SDS max hammer.
Definitely go with the bigger hammer... you'll need SDS max or spline
I can't remember if HD has the tile SDS chisels or not. I believe lowes does. But the will be sds plus, not sds max. Need to find out if the drill you are using is sds plus or sds max. Menards is the only store around here that carries any sds max bits. Besides the supply houses.
Also the tile bit isn't a must. A standard 2" or so chisel bit will work fine in an SDS for removing tile. Just have to get the angle of the drill right. You chisel a bit and then lift up and pop the tiles. Like I said before depending on how good of a job the installer did some will pop full tiles right off, some will take a lot of effort to get little pieces to chip off.
Call a rental store for the 6" scraper bit to get the thinset off. It's well worth the 12 bucks or so they will charge for the day. Again make sure the bit and drill are compatible. I used to rent one when needed until I bought my own, they are pretty expensive.
What flooring are you planning on putting down afterwards?
So the dewalt?
The SDS max is a BEAST with a bosch 3" chisel. WOW
