anyone know where i can get some from?

i need them to fix the dyson which i haven't broken, yet but all my bits aren't long enough to fit into the recesses so i'm stuffed

and even thoguh i've got an extension for the bit in the form of a 12" long bit holder, the thickness of the bit holder is too big to fit in the hole as well

so where can i get some, today preferably, to get me out of the situation i find myself in?
