Left Hand Holes?

[gator]

I do know that for multiple head drilling/boring that there is a use for left-handed drill bits. But, I just received today the new Harbor Freight sales flyer and in it they are offering Left-Handed Drill Bit Sets. When would one use a left-handed drill bit other than multiple head boring?

To drill out a broken screw or bolt. I use them all the time in the machine shop.

They could also be used on a lathe with a reversing switch
