I'm still using the old brace and bit and finishing off with a chisel,
what do you do?.

I use a battery drill and chisel. If you're only doing a door or tool,
specialist tools are seriously overkill. Ensure your chisels are sharp,
though. I bought an el cheapo bench grinder for a tenner to ensure this.
Great for paint scrapers too.

Thanks. I just went out to buy a new flat bit and ended up getting an auger -
they have hex shanks these days to fit in a battery drill, I didn't know that
before. I think the auger will be easier to keep upright.

As for chisels, my Mrs bought me a lovely set of Marples yellow handle chisels
last year and I'm keeping them just for fine jobs like this. For sharpening I
use a bench grinder too, plus a small wet stone.
