So you didn't get the wooden box with chuck, spanner and set of four Imperial collets then?

No great loss, compared to the ER32 I now use, it's a piece of dung. Millling cutters from yesteryear only.

I tried inserting a bolt in the back of the 1/4" collet to give it something to press against so I could use an unthreaded cutter, but it didn't have the grip.
