My DeWalt SDS drill turns but doesnt hammer.
Someone siad there's a spring inside which I may have broken by pushing hard on the drill trying to drill down through concrete.
Hpw easy are these things to repair,
or shall I keep the plug and lead and dump the rest?

You shouldn't have to push at all, thats the whole point of SDS.

Nothing to lose by stripping it, if you are used to doing such things. I
expect spares will be available, but may not be cheap and you may have
to pay import duty from USA. Certainly worth trying if it is otherwise
in reasonable condition. (But Chinese ones are cheap and certainly
adequate for my limited needs).

So far as I am aware, there is no spring and you should not need to
push SDS, they work by the bit bouncing off the hammer. The bit ends
are supposed to be cleaned off and greased, before insertion in the
chuck. No grease, means the bounce does not happen.

I agree, if its going to be binned then rip it apart....nothing to lose.

Have you Googled the model for spares? You might also find an exploded
view of it.

Hammering doesn't engage until it's pushed. Basic physics says it could hardly be otherwise.

If you push, the hammer action stops. It is a matter of just holding
the drill against what ever you are drilling, which allows the hammer
action to begin.

In mine, there is certainly a weak spring which must be overcome first,
but I agree it is nothing like the "wavy washer" system in an ordinary
hammer drill. OP's problem doesn't sound like a broken spring to me,
more likely something clagged up with dead grease and stone dust.

Yes indeed, you need it especially to start with to keep the hole on the
right place at least, so they should be able to manage that OK. However I've
never taken a hammer drill to bits.

Define 'holding', though I never found them very good, but then,I'm cack

I have two here - an ancient and heavy Aldi fixed speed one, plus a
more recent Lidl item which is variable speed and reverse. Apply a lot
of pressure on either one and the hammer action declines rapidly. I
have used Bosch, DeWalt and numerous other makes - the trick is always
to let them do the work, never push, just steady them gently against
the job. The SDS hammer action is produced by a lump of metal rising
and falling on the end of the bit holder. In all cases, apply too much
pressure on the thing and it can kill the hammer.

Obviously too much force stops it. Obviously no force stops it. Only on usenet do people debate such inane things.

Well, you hold the drill at the point where you intend the hole and
apply just a little pressure. Too much and the SDS action fails. It is
not a brute force instrument, or rather one which needs brute force to
be applied, it does the work.

+1It takes a small amount of pressure to engage the SDS action.

If you push the hammer function engages and if you don't push the drill
just rotates without a hammer action. The same is true with chiseling
with a rotational stop.

They seem to do spares for Kango circular saws! I didn't look far but no
exploded diagrams found.

It's a SDS drill. You ram it into the wall and the drill does it's job:-)
