Same deal as always, 100 points to whoever can explain why these two have different designs.... why wood (pun intended) you prefer one over the other ?
Or why wood you use one and not the other ?

Mark, please dole out the points, or else I will from my "pot".
from the reasearch... "it should be clearly understood that the double thread bit is intended for soft wood, the single thread for hard wood, as the latter will not clog as readily as the former, while if the double thread were left course enough not to clog, it would make the bit bore too hard".
I only have two of the double thread bits, was gonna go out in the shop later and try to drill some cedar and hardwood and see for myslef, but the shop is COLD. we in central IL got hammered last night with freezing rain and a snow cap.
