Drill bits can have difficulty at faulted zones where the lithology transitions and can be comparatively "loose" allowing for all sorts of problems. Consider as an example, a high torgue rotation pressing hard against hard rock suddenly breaking through into an area with looser ruble or void space to the left or right and the pipe and bit glance off to the left or right, probably bending the end of the pipe, wedging the bit, etc.
When I saw the second wedge, which had to be retried before success, I also assumed the first was abandoned with lose of metal downhole at the fault.
