Those are for putting holes in masonry to fit plugs for screws. Back in the middle ages when I was an apprentice, we used them when there was no power handy.If figured they were older.retired machinist friend said he thinks they are for drilling cast iron but he's not sure.any ideas.i'm gonna chuck one up in drill press and see what it will poke a hole in
To use, place pointy end on wall and belt the other end with hammer while twisting the tool. Very handy if you needed only a couple of holes and didn't want to waste time running an extension lead.
Those tools look unused, as mine have the mandatory mushroom heads on the handles. A good tool for deforming the threads on the undersides of tee nuts to stop you jacking a piece out of your mill table.

P.S Let us know if they will drill cast iron.
