"O" Size drill bit

[renowb]

Is there a drill bit that will replace the O size? Or work in place of it? I don't have one.:question:

8mm should do the trick

I agree.
The "O" bit is .316",
and the 8mm is .315"

I find this very helpful. I use it frequently because my computer is close to my workshop.
