I really hope that someone can help me here.

I am in the market for large diameter collet chucks.

1. A2-6 spindle nose. I am looking for 3 chucks and collets that will be able to give us a capacity of 80mm.

2. A2-8 spindle nose. I am looking for 1 x chuck and collets that will be able to give us a capacity of 91mm.
