Heres a spiral drill that followed me home today. No markings. Only reason for buying was I hadn't seen one like this with a screwdriver type handle. Chuck is bronze or brass or beryllium or some copper colored material. Anyone have any history on this type of drill ? I'm guessing its older than me.
Have not seen one....
The first thing that strikes me as odd, is it has a non-keyed chuck....
Some kind of variation on the Archimedes drill, looks like. Quite cool!
THAT DRILL IS TOO COOL, AND YOU ARE RIGHT, I HAVE NEVER SEEN THIS BEFORE. VERY COOL!!!!!!!
