I have been using a 30V cordless "challenge" drill from argos for

drilling into concrete lintels.

Any percussion drill will struggle, including powerful mains ones. You
need an SDS type - they *really* do go through concrete like a hot
knife through butter. You'd be looking at a mains one, though -
cordless types

Depends how big the hole needs to be. With a 6mm hole it will be more or
less instant. For a 16mm hole it takes a little while, for anything over
20mm it can take minutes... (With rebar making things difficult.)


Well, yes. But I was describing the difference between an SDS and cordless
hammer drill. The SDS would still seem like a knife through butter
compared to trying to drill a 20mm hole in concrete with a cordless type.
