After getting my first chuck and all of the sets of jaws that I thought
I would need, I found that I use three jaws; a small set on my small
chuck, a large set on my big chuck, and a smaller extended set (one
inch outside, and 1/4 inch inside) on my other small chuck. It got to
be a hastle to change jaws, so I bought an extra chuck. All of my
chucks are Vicmark, and I have used and abused them severely, and they
hold up fine.
