Collet holder

[Paul RadfordParticipant @paulradford79614]

1. I have a collet which is stamped Vs which I believe is Schaublin? Does anybody know where I can get a collet holder to fit this please?

If you have the spec why not make one?

I’m a novice so not ready to make one yet!!

Looks like an ES25 to me, similar dimensions as the ER25 but without the withdrawal groove so is sometimes difficult to remove from the chuck unless there is access from the back end to poke it with a drift.

You will always be a novice if you do not try, go on push yourself! Not everything comes out of a pretty box.

As above, the collet is a Schaublin one. It has the same dimensions as a modern ER collet. You can look up ER collet dimensions and confirm the suggestion that it belongs to the 25 series.

The difference between the Schaublin collets and ER collets is the retaining groove in the ER collet and the lug in the nut that registers in that groove and pulls the collet from its seat when the nut is loosened. See:

If you want to use it, the easiest way is to buy a standard ER25 holder and retaining nut and modify the nut. You can buy ER25 nuts alone (around £5.50), so you could buy a spare one and practice on that. If your attempts are not successful, you would still have a chuck and nut that could be used with modern collets.

When considering options, bear in mind that ER25 collets are £5-£6 each brand new.
