Unfortunately, if they dont go all the way through, theres no way to extract the slug thats left, so theyre only good for through holes. While many manual machinists use center drills for this purpose, a true spot drill with no small diameter pilot is a better bet. The alternative for blind holes (which also works on through holes, just not as fast) is to use an endmill and interpolate the hole. Twist Drills can go down 5 diameters deep without issue. In general,pilots are discouraged for holes smaller than 1 (25-30mm). It takes multiple charts to cover maybe 3 or 4 dimensions.
