The top one is a "hole Saw" and was used in construction of buildings (carpentry) when they were pegged with wood dowels in the 1800's. The second, is a bicycle chain driven drill, it was invented by a guy by the name of Walt DeWalt. did I win the table saw? I can pick it up as soon as it is available.
The century is correct and "specific" was filled in nicely. The trade happens to be a smidgen off, though.I suppose I might have to give you 100% for keeping up with my twisted self as a bonus (one word).
If you feel the incessant urge,and your tongue is sharp and quick,leave a worthless thought for mewhether cool, or fun, or sick.
