Questions about this item
Does the Drill America 61/64in bit include a case or only the single cobalt steel drill bit?
The package contains one 61/64in cobalt steel drill bit with bronze oxide finish and 1/2in reduced shank; no case or additional accessories are included.
Should I choose the 61/64in size or a different diameter for a 1/2in chuck?
The 61/64in bit has a decimal equivalent of .9531 and a 1/2in reduced shank, so it fits a 1/2in chuck while drilling a larger hole; select a smaller diameter if you need a smaller hole.
