When I purchased my mill it came with two styles of collet holders

This collet works fine.

This collet when tightened still has space at the ends of the collet. Collet does not tighten up, any ideas.

Also included with the collet parts are these whatchamacoletts aneyone know what they are for. They almost look like they would take up the space in the second collet set but they have an internal thread, a different size for each one.

The first set is known as DA series (double angle). My DA180 (or 180DA) collets go up to 3/4". Yours may be the next larger series.

Your second Collet chuck is known as a Dead lock chuck. These chucks hold threaded end mills the different threaded plates fit the different dia. end mills. The plate and end mill are placed in the collet then sliped into the chuck then the chuck lock nut is threaded on the chuck by hand. The end mill is bottomed in the chuck by turning it in till the end mill bottoms out, now you tighten the lock nut.
Note these chucks are for threaded end mills only. One maker is Clarkson.
