archimedes mini drill tool for watch hole resizing jobs

[db1]

i was thinking about this tool, it can be useful, the archimedes twist mini drill type tool.

it is non powered, which means it works by pushing the handle against a surface to spin the drill bit and drill the surface, this way making it possible to work very gently for precise hole resizing, hole countersinking jobs.

other than having a high rpm powered mini drill that turns very high speed, and before you know it- you have drilled too deep or countersinked too much.

did anyone tried this type of tool for watch making jobs ?

here's a link one of these (only this one's chuck i think is too small for lugholes, or tube hole jobs etc..)

Doubt it would work on lugholes. The SS have heard is very very hard and difficult to accomplish correctly even with a high powered drill press.

yeah, i didnt mean it can be used for "drilling" the SS, but more like to resize existing holes that needs maybe a half mm or so, or for countersinking tube holes.

do you think for these purposes it won't work as well ?
