Lovely masonry. I agree with LeD. Mine will also zip through any rock. If you ever do hire one, secure the stand thoroughly, ask the firm for advice on how to erect it and take care, these old stone buildings look great on the surface but in the middle of the wall may be loose stone and tuf ( tuv?) which may jam the core, hence you need a really secure stand. However, I understand that you are only making a hole for your electric socket, in that case, the drill I previously posted on this thread is absolutely adequate for all stonework.

If the granite you are trying to penetrate is the dark grey/blu coloured stuff just give up and put the house on the market. don't ask me why. Just give up now. Looks like this......
The correct tools should deal with that ordinary "speckled" granite OK. The stuff I have had to deal with is a solid colour. I've had intimate and often frustrating experience with soft to medium (yellow to coppery brown) hard (black & white speckled) and damned near impossible (solid slate grey) and the latter always ended up with having to remove the stone and replace it with a softer one that could be drilled. The worst job was when I was replacing some heavy oak beams that had rotted at the ends where they enter the wall. The owner insisted I didn't reduce the size of the ends of the new beams to fit the existing holes in the stone but wanted the holes enlarged. I should have told him to find another mug and walked off the site.

If that is lime mortar and the zinc downpipe is bedded onto it (in contact) then it is not going to last very long.
