摘要

The extraction of broken drills and reamers from deep holes in valuable work-pieces makes it possible to return the material to normal use. One method for accomplishing the extraction of broken drills and reamers is by spot welding a suitable welding rod to the broken tool and easing tool out of the hole by direct pull, without twisting.
