AT3 Class Tooling

[rakes]

What is the repeatability assured by AT3 class tooling?
What are the other standards in vogue regarding tooling for CNC Machines. Is there anyhting better than AT3?

Thanks

First let me say, you may be chasing tolerance ghosts unless all conditions are IDEAL. Conditions inside of a machining center cabinet are almost always less than ideal. Here is a link from MMS online concerning the selection of toolholders.
