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.

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

Interesting. How do you do this?
