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.
