What are these two style bits used for?

[bagged89s10]

I bought a bucket full of taps, drills, mills, and Allen wrenches and just started sorting thru them. I just don't know what these 2 style bits are. Can someone please tell me?

1) are these screw extractors?


2) I believe these are for a mill?

The first ones are ez outs used for broken bolt extraction.
The second ones are a mix of counter sink bits.

#1: Easy outs for removing broken bolts.
#2 center drills used for drilling the end of round stock for a lathe center. Used to drill a center punch location for accurate start of a drill bit.

Thanks. I edited my post and answered my own question about the first ones.
