Not such a great idea to "neat" channels. They stand out like a sore thumb
when replastered. I use a gouge in an SDS drill for chasing into walls.
This makes a very neat job but leaves a slightly ragged edge which can be
plastered invisibly.

The gouge third from left is very useful.

A rake is also very handy for this sort of work:

As is a comb with a TCT tip but I can't find a picture of one of those, I
buy them at my local supplier. Combs are excellent for making a flat bottom
to any channel and they also make short work of punching in the edges to
the channel. If I had to use just one SDS chisel for chasing walls, this
would be it.


and not a drop of dust to be seen
anywhere?

Bwhahahahahahahahaah.
