What size drill bit should I use for h20 innovations slim spout? Thanks

I'll go out on a limb here and say use a 19/64" bit. A 5/16" might work but it is over sized and the tap may not seal.

I use both a 19/64" and a 5/16" bit and I really can't tell a difference on seal on the 19/64" Lapierre spouts. I have 3 of the $ 20 Canadian bits from Bascoms, so they do make a nice round hole and that helps too.
