I'm bartering for an older model Central Machinery 10", 12 speed drill press. Although it has the chuck key, it doesn't have a chuck release key, or any other tools. I assume the chuck release key must be use if you ever needed to remove the chuck. A search for a chuck release key has left me clueless. Maybe I'll never need one, I hope. To give you an idea of the possible age of the drill, the table is round. It does have the table vise, too.
This is an older unit from Harbor Freight. Perhaps twenty years old. The deceased gentleman built a beautiful portable table for it. His daughter was asking $75.00. I offered to properly prune her ornamental trees; about an hours worth of work.
