  • Chuck Mounting Question

    What is the difference between an A1-5 and an A2-5 mount? I read somewhere there is "no difference". If there is no difference why do they have separate designations?

    Never heard of a A2 mount.

    May be this will help. What is it on? What kind of machine ?

      A-1 Has tapped holes on both inner & outer bolt circles.

      A-2 Has tapped holes on oter bolt circle but none on the inner bolt circle.

        Thanks Les,

        According to the diagram an A-1 will fit an A-2 but not the inverse. That clears it up. The machine is a Haas TL-1.
