Since I don't always want to use power tools to rework a hole, I was looking for a hand tool. I found inspiration at Rasle500, thing:16682 and at aubenc, thing:16839. But the models did not suit me in the present form, they were too clumsy for me. A further weakness were the stuck collets, after one screwed tight. Therefore I designed a completely new holder, where only the collets are compatible. The holder is slimmer and has a diameter of 32mm and a length of 96mm. It also has an ejector that allows you to release tightly fitted collets with a light tap.

As always, the thread needs a few passes until the unevenness caused by the printing is smoothed off.

Recommended by me: Box for Drill Holder and Collets by Syntaxcuemi. This is a very nice addition to my drill holder.
