Good excuse to buy a Cole drill?

Drilling sixteen 1/4-20 holes in 3/16" wall 304 sections; no electricity is a big plus due to environmental factors.



Then to tap them; no lube is also a bonus (same factors), would a forming tap work better?


I know, that's why I thought of the Cole drill.

It's for location, not holding. Has to leave a flush hole when unoccupied, so no rivnuts unless there exist flush ones (if so those would be really good).

Any reason that can be found, is a good excuse to get a Cole drill. The V-block base accessory is very useful.. get one with that included or fabricate one.

Cole drills are not only useful where there isn't electrical power, but with an adapter attached to the spindle's top end (crank handle removed) a drill motor can also be coupled with a Cole drill.

I'd check if the SS is magnetic before buying a big drill like that.
