Something like so:

BS26S3-5kg-SDS-Plus-Drill


Couple of questions

1) if I get an SDS is there any real reason to keep my normal drill? They
still work like normal drills on wood/metal etc AFAIK - downside is that
they are much bigger!

SDS dont substitute well for an ordinary drill. They have the wrong
type of chuck, and if you fit a chuck adaptor you end up with a drill
that's excessively long, heavy and the bit waggles. They also dont
turn as fast.


2) Any difference between the difference type shapes? i.e the one I linked
above as opposed to the normal shaped drills that don;t have the fat bit
infront of the handle

the relevant differences in SDS a
- weight, 5kg gets tiring
- 1 versus 2 versus 3 function drills - get a 3.
- impact energy in joules
- whether the bit locks in position for chiselling
- and reliability/brand


3) Does the weight 5kg or 6kg just mean the higher weight the more heavy
duty?

not really, compare the impact energy


4) Can the chisel action be used for something like taking out pointing on
a patio?

angle grinder much better.


Anything else to think of?

On mine, the chuck quick releases from the body, and it came with a
standard chuck too, with same quick release mechanism (as well as
being a quick release check). Don't know how common that is, but it's
certainly very handy. There's no hammer action available with the
standard chuck - it deliberately doesn't engage with the hammer, so
you can't use any of your existing hammer action masonary bits, at
least not in hammer mode.

They also dont
turn as fast.

but have much higher torque - the drill doesn't stall just because
the bit jams. Either the drill body spins round, or the bit snaps
(or both), or if you bought one with a safety clutch, the clutch
slips providing you have a good grip on the drill, usually avoiding
a trip to A&E.
