The manual says not to use the standard 13mm chuck with the SDS drill when
in hammer mode. What is the actual problem with doing this? A standard
chuck can cope with basic hammer drills - is it the heavier force from the
SDS drill that could be a problem?

Its just that I need to make a large hole through a wall for pipework and
have a 40cm x 20mm standard masonry drill bit but only a short 6" x 22mm SDS
drill bit. Just wondering whether I can make use of the longer non-SDS
drill bit in hammer mode in the standard chuck. What's the worst that can
happen?

Thanks

Because it will mush the chuck.

Much heavier impact.

The chuck will last for exactly 3 holes, and the bit somewhat less.

The question here is am I brave enough to tell the truth...

My first SDS (a £35 NuTool, which lasted only a little longer than the
chuck) came with a free SDS chuck. Not thinking things through, I
proceeded to use it to drive a 7mm ordinary masonry bit through a stone
wall.

The drill bit very quickly gained the appearance of a sharpened pencil,
and the chuck was never the same again (I couldn't actually undo the
chuck!).

Ah. Here's where I admit I have a similar problem with an identical

experiences certainly vary with the NuTool
got mine from Woolies with the 5 year gntee
& it's drilled 16mm holes with the add-on
chuck, chased trenches in concrete, hacked through
granite & it's still going fine - for £27 & five years of gntee
.....not bad.

The way the chuck locks into the sds hole does not allow any fore and aft
movement, therefore the little hammer inside will smashing against an
immovable object and will get damaged.

Drill the hole with a small bit all the way through then use a larger bit
from each side , with hammer off if you use the grippy chuck.

I think you're mistaken there.

That sounds more thought out. I'd agree with that bit.

Well , that is how my wickes sds drill and chuck design is, so I assume
others are similar. The chuck adaptor which fits into the sds slot has only
one depression in the side, this effectively locks the adaptor solidly into
the sds chuck of the drill and allows no fore and aft movement (unlike a
drill bit, which can float )

That'll be the cheap crap you've bought there then. None of my SDS to
conventional chuck adaptors, nor any I've ever seen, have been any
different in their design to standard SDS bit shanks.

I was wondering whether I could use a standard masonry bit in it but without
using the hammer action. I would imagine though that without the hammer, it
wouldn't break the brick so much. If a basic hammer drill struggles then
surely not using any hammer would be worse? Depending on the substrate that
I've been drilling, I have been able to use masonry bits without hammer
sometimes. I often start the hole without hammer to get a more accurate
start and then find that I can carry on with it.

[T] Possibly, yes ..

[T] Proreably not. (depending on hardness of the material)

[T] Not a bad plan. I generally use my DeWalt (non hammer) battery
drill for everything (to start with at least) including drilling holes
for wall plugs. Sometimes all goes well to start with then you hit a
hard bit or stone and that's when the hammer would come in. You can
get a hand hole 'punch' (?) for making plug holes and I use one of
those to break the stone before finishing with the drill.

I used my Challenge one yesterday (+AKM-29, Argos) for the first time and
it made easy work of a 20mm hole diag through a 30cm of hard brick
wall. ;-)

All the best ..

If it's like my DeWalt, it wouldn't work anyway - the chuck shaft isn't as
long as a drill and won't make contact with the mechanism.

On my Stayer SDS the standard chuck adapter is built so that it
disables the hammer action when you use it.

Ooops - finger trouble - sorry about the no added content post :-(

Nobody seems to have mentioned yet that SDS bits are not that expensive from
builders merchants.

Surely worth buying a new bit instead of risking your existing bit, plus
add-on chuck.

Full on SDS is far more effective that any old style hammer drill
combination.

Regard it as a wise investment :-)
