      I've never had any reason,  in over 60 yrs machining, to see a reason 
to use a
      left hand drill unless you're drilling a rotating shaft from both ends 
simultaneously.

      Why are they needed ??

      I've used many Hanson- Whitney taps but they are not my favorites.  Had 
alot of
      them that were improperly heat treated and were too hard and snapped 
very easily.

     I preferred Cleveland drills and taps.
