One of my 1.5 meter SDS drill bits is stuck in the wall.

The drill, a Titan, appears to have a clutch which means it makes a noise but doesnt turn.

The wall is an mix of stone and lime cement.

Any tips on how to get it out please?

I did that - drilling through an 11" cavity wall the cavity wall
filling melted around the drill bit, stuck solid. Cut it off with an
angle grinder and left the rest in place.
