Nope... don't pay commission.

Why do you think the prices are so low :-)

That's what we're here for....  Now, if only the group could earn commission
;)

SDS drills have a quick change chuck that don't require a key.
Consequently, you need SDS drill bits which have a keyed shank to mate with
the chuck.  The good news is that these bits aren't that expensive
http://www.screwfix.com/shop_product.html?0762 and last much longer.

A normal 'percussion' hammer drill isn't particularly effective at drilling
into hard materials like concrete (it won't!).  The SDS variety have a
sliding hammer that strikes the end of the drill bit - this means they WILL
drill through concrete!  They also drill much more quickly, as the sliding
hammer generates more energy.

I have http://www.screwfix.com/shop_product.html?1493 and
http://www.screwfix.com/shop_product.html?8060   Only the mains DeWalt one
has rotary stop.

Most SDS drills have a hammer and hammer stop mode, like ordinary 'hammer'
drills.  Useful for drilling into wood, screw driving and using attachments
that must be set to hammer stop (or they tend to fall to bits!).

Rotary stop is where the drill doesn't rotate, but the sliding hammer is
still in action.  Not all SDS drills have rotary stop.

> * Chisels, on a drill?

With SDS chisels http://www.screwfix.com/shop_product.html?5618, you use the
rotary stop mode and you now have a power chisel/bolster.  As these drills
deliver many blows per minute, it is more effective at cutting through
bricks etc. than you with a hammer and bolster.

> * Fancey attachements for chassing coduits and back boxes?

The conduit chaser http://www.screwfix.com/shop_product.html?6724 is a
chisel shaped like a scoop and is designed for cutting channels for cables
(like lots of CAT5).  Back box sinkers
http://www.screwfix.com/shop_product.html?16114 are an easy (but messy) way
of making a square shaped hole in solid walls.  There are two stages
involved here - firstly you use the cutter to create a large, circular hole
that is deep enough for your box.  You then switch the drill to rotary stop
and hammer in the square cutter which removes the corners left behind.

That's how I started.  I now use an SDS chisel to do the dot joining :)
(still haven't bought a channelling chisel)
