Having 'found' a project (repointing) that lets me justify to SWMBO why
I should get an SDS drill, while perusing the Screwfix catalog one thing
struck me - the maximum depth quoted for masonry drilling, even on
fairly expensive drills, is often less than an inch. How is this right?
Surely SDS can go deeper than that! What have I missed?

The depth you can drill is only really limited by the length of the drill.
The diameter, now, is a different matter. ;-)

If you're repointing an old house with lime mortar, I'd be careful not to
rake out too much. On mine I found it easier to do by hand using a
plugging chisel.
