My house has 9" concrete walls and I want to replace all the radiators. My
standard run of the mill Hammer Drill cant cope with the task of drilling
the holes therefore I want to get a SDS type.
My question is, which is or are the most important specifications I should
consider when purchasing one. I assume Impact Energy is high on the list.
Additionally any recomendations of make and model would be welcome.
Not really, or not as you might imagine. Higher weight ones
are much more tiring to use, but not any better for many
typical jobs. Even the lowest energy one will have no problems
drilling mounting holes for radiator brackets. It would be more
of an issue if you were drilling holes for larger pipes.
