I posted this to the tooling forum. Thought I'd try here.
Does anyone have any general opinions on any of these 3 collet chucks? The one from littlemachineshop is quite a bit less expensive. I need to order one but want to make sure of the quality.

What will you be using this on and what for? Production or one or two?

As of now, it is for a single low volume production part projected at 500/year in lot sizes of 12 (half bar) or 24 (full bar) at 2 clampings per part. It will be mounted to a custom arbor with a 2.500" clamping post & chucked into our existing collet chuck (Quick grip) employing a 5C expanding mandrel.

However, It will become the modular component of any future parts requiring ID clamping or special configurations that can utilize a 5C (eccentrics, special shapes, etc...). Therefore, I don't have a concrete answer to your question as I don't know what my future needs may be. But I do wnat a quality unit that will last.

You might want to consider the type that can be adjusted to remove run-out. Adjustru?

Yes. I was leaning that way myself.

I bought a Master Jaw System for 5C collets for a Kitagawa B-210.
Even with a discount it was pricey... and in the end, I don't think such a great deal.

The jaws need to be kept pristine clean, the position of the collet in the sleeve is too critical, and the run-out varies with each time you push the button. Takes too much time.... in the long run, you're better off buying the real deal.

I can't recommend this system. Not bad, but not good.
