Can you use a drill to tap?
A drill press can help keep the tap aligned much more accurately than you can do freehand. There are two functions that the drill press can serve to help you tap a hole. The other function is to keep light pressure on the tap so that it will cut cleanly as soon as you start turning it into the hole.

Which tap is considered a general all purpose tap?
Hand taps are for general purpose applications such as production tapping or hand tapping operations. Taper, plug and bottoming styles provide versatility in tough materials, blind and through holes. As to general physical dimensions, spiral point taps are identical with the standard hand tap.
How do you measure tap drill size?
As a rule of thumb, for Metric threads, the tapping drill can be calculated by subtracting the pitch from the diameter of the thread. eg for an M5x0. 75 thread the tapping drill is 5-0.75mm = 4.25mm. For Imperial (inch) threads the tapping drill size is calculated in the same way, diameter minus pitch.

How to calculate the required diameter of a tap hole?
65%, use 65 (not.65). (M6) 6mm x 1.00 tapped hole, follow first column down to 1.00 threads, then across to 75% of thread. This figure (.9743), when subtracted from 6mm diameter, is 5.0257, which is the required diameter of hole. See equation: M6 – (1.2990 X 75) = (6 -.9743) = 5.0257mm
