Apologies if this has already appeared, I posted it last night and I can't
see it on the ng as yet!

Hi,

I had a quick look to see if i could find this in a previous thread or in a
FAQ, but couldn't find it, so apologies as I'm sure it's a regular!

I have limited tools available and i need (the nagging is getting
unbearable!) to drill a number of holes above a window which seems to use a
concrete lintel.

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?!

Many TIA,

Jon H
