For Imperial (inch) threads the tapping drill size is calculated in the same way, diameter minus pitch.

How deep should a tapped hole be?
As a general rule for holes 1 1/2 to 3 diameters deep, the hole should extend approximately 1 1/2 diameters beyond the tap's deepest point. Threads deeper than 3 diameters may require even more clearance at the bottom of the hole, because the deeper threads will produce a greater volume of chips.01-Aug-1995
