About the WW collet with 1″ blank
To make it easy for you to make your own custom tool holder, we now provide a 1″ diameter blank collet without hole or slots. It is made from free machining steel so you can drill and machine it to whatever shape you need. The shaft is pre-machined and threaded to accept your WW collet holder.
Though this is mainly a general purpose blank that takes advantage of the WW collet adapter and drawbar to rapid application in the lathe or mill, if you want to read more about WW collets, see the links in the Instruction tab. Sherline also makes a #1 Morse blank.
