I have been using a 30V cordless "challenge" drill from argos for about
3years and it has served me well. It does struggle a bit when 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
are an arm and a leg.

These have been discussed here at great lengths since they can be bought
from about 30 quid upwards. I've had a De Walt 566 for many years which
cost a fair bit then but can now be bought for around 100 quid.

If you do a Google search on this group on SDS I'd say you'll get a good
evening's reading...
