I've purchased a Dewalt D21580K dedicated dry diamond drill.

The manual insists on using the DeWALT D215804 Dust Collection Device

I will try without it, but is it that important? I really do not
understand how it can collect much dust being so far from the actual
cutting.

Would the end of a vacuum cleaner placed by the hole be any better?

Also, the manual insists on using a stand for dry drilling above 100mm.

Would it be really needed for drilling 127mm holes in breeze block and
perhaps in masonry?

Kind regards,

I have a dry diamond cutter set up (Marcrist not de walt) and using
the dust extractor is almost essential to keep the cutters clear of
dust build up which jams the cutter in the hole. Typically it makes a
bloody awful job into a simple one. I attach a Henry to the spigot
when cutting.
