Antique Drill Bits in Original Wood Box

by Ralph Martin
(Pittsburgh PA area)

These were my Grandfathers (1874-1979). I have no idea why they are sharpened the way they are. Strange... The smaller drill bit has a #10 on the brace chuck end and a logo? on the shaft. See hand drawn photo. This one is 24" long.

The larger drill bit has a #14 and S.T. Co on the brace chuck end. This one is 29.5 " long.

The wood box has a label on the end but is not readable.

I would (no pun intended) like to know more about these drill bits if possible.

Thanks
