Using a #28 split-point bit, drill three one-inch-deep holes in a circle in one side of each of the 48 cylinders .625" from the center and spaced 120 degrees apart.

Why a split-point bit?

Regular jobber bits tend to 'walk' away from center and split point bits don't. I'm not entirely sure why that is.
