Diamond disc wall chaser set on "shallow"?

You mean the two disk type? Will the inset bit come out readily? Perhaps
if you can set the disks up so that the "gap" bit is (say) around 5 mm
it will come out easily with a manual or SDS chisel. It's another good
thought.

You can swap the discs around to get a double disc - I did that when
cutting wide groves to take some stitching across a crack in the floor
screed. Works OK IME.

a double grinding disc would get 12mm, maybe a fraction more
