If you mean ripping up a whole floor, then don't use an SDS drill for it
- they aren't up to it. Hire something to do the job.

It will chase the walls, but I would not want to hold one of these cheap
heavy jobs up for too long.


not the entire floor, just an area large enough to sink a bath into the
floor about 6 - 8"


I still wouldn't use an SDS for it, it will take ages, and possibly
knacker it.

ISTM that the chiselling function of an SDs is really a replacement for
that where you might have done it by hand with a hammer and cold chisel
or bolster, - chasing, cutting out holes for back boxes cutting out
holes for waste pipes etc.

They aren't breakers.

I'd still hire a small light weight breaker/demilition hammer.
