Finally got a chance to use my new drill bit index (9/16"-1").
11/16" was called on today!
This drill index is reserved for non-ferrous metals. I have another for ferrous materials.
Had a stack of aluminum bars that needed drilling. 32 bars with 2 -11/16" holes in each for a total of 64 holes.
One not so shiny drill bit in the index now.
