if you can open the chuck up, you can then inspect & clean it. And not
apply oil to the threads. When I say open up, I mean once its removed
from the drill, clamp the outer body (not the tightening ring), and
tap the stem moves toward where the drill was. Probably best clamp the
outer body in a vice in 2 indented bits of wood.

If it is one that needs a key, chuck it out anyway: put the key in one of
the holes and hit it smartly with a hammer in the same direction the drill
turns. The chuck will then unscrew.
Make a note of the stem size and buy a new click stop one from Screwfix (or
buy a cheap drill from Lidl or Aldi and swap them over.) Some examples:

You may find cheaper places than Screwfix nowadays too: 'pound shops' and
the like being good bets, or even skips where people have chucked them out
just cos the fuse blew... Why didn't you keep the chuck from the Bosch?
They used to be very good.

Above technique is fine - but check its not got a retaining screw as
well (most drill with reverse will have one). Open the chuck wide and
look down the end - there may be a screw to remove - possible with an
anticlockwise thread.

After it shears the left-handed screw off inside at the base, you mean?
Buying a new drill will be cheaper.
Where are you going to get a new drill for single figures? A power
devil £5 special? No thanks!
