Are these left-handed drill bits as well? If not they should be a lot of time when the drill bit bites the screw comes out.

Just to clarify the 35 piece screw extractor set that comes in the large blue case, it has USA made multi spline hex extractors, USA made spiral extractors and LEFT HANDED cobalt drill bits "made in Italy". Amazon do you ever edit out wrong/contradicting/useless answers? If not then who does/can? Having to look at multiple pages of the same Chinese items, not different items, the exact same item shown multiple times per page on every page; having to shuffle through useless/wrong/contradicting answers and reviews from one extreme to the other just takes way to much time trying to buy something. Please let us or certain people remove the answers if you won't.

Can someone tell me where these are made, what does it say on the box? TY!

They seem to be made in several places, I assume the case was made in China. The left hand drill bits are stamped Brazil, and the extractors say USA.

Made in USA of "foreign components."

Are the bottom of the reverse drill bits hexagonal or smooth?

The reverse drill bit it smooth. The extractor is square.
