Second soc question!!

Hi. I wanna try to make second soc in my gears and i hawe 5 trouthdrill. And what is better ?

Add all drills into 1 items till i got soc(if i got) or add few these drills into diferent items?

spam them on 1.

Doesn't matter at all, the succes rate for toughdrills are server wide, meaning that every 100th or so toughdrill used on the server will give a socket, has nothing to do with on what item it is, what time or what item.

1 more question !!!

So i dont get my soc in ring with 5 drils, so now i need to make again 5-6 drills and then try my luck or when i hawe 1 drill try my luck with my ring and and few days ago i again hade drill and again add it to my ring and so on 1 by 1 in few days?

And maybe some1 can say his luck with drills? how many drills he duy to make second soc in 1 item?
