Trying to justify to myself, getting a SDS drill. Does anyone use it
for the insides of external walls ? Usually use a hammer drill for this
but was drilling a hole through the external walls (16mm Ø for pipework
for a garden tap ) yesterday, was at it for ages with a hammer drill,
borrowed a Makita SDS (£3~400 worth but then he uses this sort stuff for
his work) from a neighbour and it seemed to go through the brick work
like a hot knife through butter. Thing is I don't envisage drilling
lots of holes right through external walls so is a SDS of much use
inside or should I stick with the hammer drill (doesn't seem very much
slower on the internal surfaces of external walls)?
Also if I was using a SDS inside how easy is it to get smallish bits
(say 4~6mmØ)for SDS?
I usually use my ordinary hammer drill for the bricks on my house - but
your bricks may be harder. My reason is that my hammer drill is more
accessible than my SDS one which lives in its case. My hammer drill is
used for drilling other things so is usually on the workbench. ;-)
But I'd not be without my SDS for hard masonry or chasing, etc.
I've certainly got small enough ones for the common wall plugs.

If you wanted a relly good general purpose SDS then something like:
may be more appropriate than the Â£300+ models.
I tend to find that I use my combi cordless for most things, and the SDS
for chiseling and any hard masonry drilling - I never feel the need to
touch the ordinary mains drill any more! If however I did not have the
combi then it would be a different question.
If you go for a 2kg class SDS then you can use it as a "standard" drill,
but it is a bit longer and hence harder to get into tight places. To use
very small drill bits you may need to fit an alternate chuck (sometimes
you swap the main SDS bit holder for a conventional chuck (like on the
Bosch GBH range), others use a SDS to chuck convertor (like the
Makita)). For tasks like screwdriving you may find it has the torque and
control (if you get a decent one), but the balance point is all wrong
for one handed operation.
If you get one of the 6kg cheapies then these tend to be pretty poor as
a replacement for a conventional drill (poor speed control and just too
big and heavy)
I don't have a hammer drill any more.
I have a Bosch SDS Multidrill which has exchangeable chucks for SDS or
conventional drills. This will tackle anything that I need in concrete or
masonry of any substance. Mostly SDS is used.
I then have a number of cordless drills up to a Makita 18v (non hammer)
which will do everything else. Light weight blocks don't need a hammer
I have a set of SDS wood augers in the common sizes that I got from Screwfix
a few years ago. They are very good, and no problems with accuaracy (as
long as the hammer action is off). The only problem I have come across with
some harder woods is that if the bit binds up in the timber then the clutch
on the drill kicks in to prevent snatching and you end up stuck - especially
if like my TE-25 your drill doesn't have a reverse !
FWIW I replaced a truly nasty NuTool SDS+ £40 horror with a Makita
HR2450X which was £120 from Lawson-HIS including 4 or 5 (identical) sets
of small SDS+ bits. I wouldn't be without it. It lives on the same
shelf as my Bosch screamer and is first choice for drilling holes in
hard materials, it also seems best at drilling plug holes in my
shatter-prone white bricks. The Bosch has been relegated to knocking
holes in steel plate for the endless trailer project and cable ways
through joists (it's body is shorter than the Makita).
SDS every time, far more control and because it drills quicker you get
less bit wobble and therefore neater holes, particulary is softer
materials. I'd avoid the real cheapies, I've got Bosch with rotation and
hammer stop, probably this one:
Well worth the premium over a conventional hammer drill and with rotation
stop can be used for chiseling and chasing.
No problem, not sure I've got 4mm but probably 5, 5.5, 6, 6.5, 7, 8, 9,

For occasional use I got a cheap one (around £30) from Argos. Now had it 4
years and its had a real battering. Much heavier than a £300 unit, and not
as efficient either, plus the rotary stop mode still turns a little. Even
taking all that into account, far better than a normal percussion hammer
Thanks all, you gave me lots to consider.
Seems the very cheap ones do the job but not very "easily" whilst to
get a "good" one takes more money than I am prepared to spend on the off
chance that I need it again.
Plan as is is to keep to the HD for inside, if I need a SDS for
anything will buy one of the very cheap (£30) jobs, but will put any
money I would have spent on an SDS in to getting a better cordless
drill (have to get a new one battery died on old one and as it was a
"cheapy" thought I will get a new better one rather than a new battery).
That is the next question Drill/driver or combi or do "they" do a both?
