Half the group are laughing, thinking I didn't switch the rotary stop
on.
But I did, honest.

Anyway, I switch it to chisel mode, and chisel away at the wall. This
works well on the whole, but the chuck slowly rotates, so the flat
plane of the chisel does not stay where I want it to. It does not
rotate unprovoked, but only when a torque is applied, e.g. when
chiselling against a bump.

Is this meant to happen? Or is it broken? Or am I doing something
wrong? Or something else?

Thanks!

Not all SDS drills lock the rotation when in rotary stop mode.
However, I would say that one which generates rotary motion in
the way you describe is faulty or not fit for purpose.
If you said what make/model, someone may be able to confirm or
refute this as normal behaviour.

Some do, some don't. In have one that does and one that doesn't, one's
a Makita and one's a DeWalt but I can't remember which is which. There
is a knack to guiding the chisel in the right direction and keeping it
fairly straight. If you fanny about with it and don;t just get stuck
in it does what it wants, you need to show it whats what.

My 30 quid screwfix special does exactly the same thing. Haven't used it
for a while, but I seem to recall just holding the chisel would fix it.
Don't tell H&S.

IMHO; using a SDS chisel (bit) and the SDS drill (rotary stop) is just like
using a manual chisel and lump hammer. I hold and guide the chisel with my
left hand while the SDS drill body is supplying the 'thumping' (technical
term) that the hammer would produce: It's less tiring and more accurate as
the bit thumper produces more effort and faster than one can hit a chisel
with a hammer. It's very heartening to discover just how much heavy thumping
and delicate tapping can be produce from one tool.

It is a known problem with (typically) the budget SDS drills, and indeed
some of the older quality brands. Better ones allow the rotation to be
locked off, and the best will allow you to set the angle of the chisel
before locking it.

Sounds like the design of some lower end models. My DeWalt allows the
chisel to be locked in a variety of positions.

Even the cheapest lock if you use a bit of coathanger and a wire tie.

Thanks for your advice everyone.

My SDS is fairly cheapo - Black and Decker, cost
£65. Looks like it just does not have rotary lock.
Still, it will do - I almost bought one that did not
even have rotary stop, not realising that some of them
do not have it.

Interesting. How do you do this?

You bend it around the chisel/chuck and a suitable spot on the drill.
It has to have enough spring in it to cope with the small amount of movement
you get with the hammer.

My £200 Dewalt doesnt have a lock either, which rather surprised me, but
being as I bought it as a drill, it didnt really concern me.

Which model? I thought they all had locks if they have rotation stop.

It's yellow if that helps! :-)

Turns out it's a cordless. Not surprised they don't encourage you too use
it as a chisel.
