Erm, box sinkers require rotary stop...

Angle grinders throw vast amounts of dust all over the place.

Both would be quicker, have less disturbance to the walls and with
dust extraction, much more tidier than having bits of block
and dust fly all over the place.

I'll grant you that *good* (aka *very* good) dust extraction on an
angle grinder may reduce the mess but that is yet another extra for
suitable vacum device hoses etc.

The attachments would not cost any more than a good drill with the
roto stop, and be much more cost and time effective.

Box sinkers are not cheap. Screwfix single box set is =A384.99, the
single and double box set with 30mm channelling chisel, 5 x 6mm
drills, circular cutter and SDS bolster type chisel is =A3189.99. The
dust extraction unit =A369.99 (Yes, =A369.99, that is what Volume 72 has=

it listed as, for a polypropylene moulding, typo for =A36.99?)

If you think you will need to do some channeling or box sinking for
a one-off large project at home, or for more regular jobs, then you
would buy the best tool for doing this, or hire it for one-off. Yes
you could use a roto stop drill, but it is not the best tool to use,
and certainly not the tool to buy on a might use basis.

I agree a box sinker is the best tool for sinking boxes but they ain't
cheap (see above) and you *still* require the roto-stop drill. For
just a few boxes a plain chisel is far cheaper. And, in my case, saves
a minimum 50 mile round trip to the nearest hire shop.

Channelling I just cut through the plaster along each edge of the
channel then zipped up the middle only minor break out from the skim
and cutting at of 6' in a matter of minutes. Plaster in large lumps
not pulversised to dust that a channel cutter would produce.
