My basic B&D hammer drill just doesn't seem to have the guts to make any
impression on the concrete. What bit should i be using and are there any
other tips you could give this frustrated DIY newbie?!

You need an SDS drill, I'm afraid. Uses a different method of 'hammering'
which is strong enough to go through concrete.

Thanks Dave, having a Google around I saw the SDS drill bits and wondered if
hiring one of the drills was the way to go.

Many thanks for the advice, much appreciated!

Cheers,
