I have aquired a KWM bushing tool that uses a chuck similar to a drill chuck to hold the reamers and pushers. I need to get a new chuck. It is held on to the shaft by a taper fit. It does not seem to be a Jacobs taper. Does anyone know what the taper is or where I can get a new chuck. It is not shown in any of the supplier catalogs.

Jim,
You may want to call the suppliers. They sometimes have things that are not listed in the catalogue.

They must be making them different now. My KWM bushing machine does not have a separate chuck. The end of the shaft is fashioned into the piece that holds the cutters and pushers. It is all one piece.

If I find out anything more, I will post it here.
