Then I'd say the right tool isn't even a drill bit!!

Measure the existing hole, and buy a 11/32 couterbore, and a pilot for the couterbore that is the same size as the existing hole, and have at it!  Much less grabbing, lower HP requirements and the like, plus the drill won't walk all over the place

pursuing invariably the same Object evinces
 a design to reduce them under absolute Despotism,
it is their right, it is their duty, to throw off such Government,
 and to provide new Guards for their future security."
