Not the ones I have! I bought 8mm 1/2/3 taps (taper, second and plug from Chronos and all three taps have a pointy end. The amount of ful thread differs so I can tell which is which, but no. 3 has a pointe end just like the other two. On the other hand the set of 10mm 1/2/3 bought from them all have flat ends, just like the RS 12mm set.

On the tap's shaft, there is one ring for pre two rings for intermediate and no ring for final cutting.
