OK, so I've needed one of these for a few years now and finally coughed up a few bucks and bought one.

Of course, now I need to know what collets fit it.

I've checked here (http://www.tools-n-gizmos.com/specs/RF_Collet.html), but none of the dimensions seem to match mine. I could be measuring it wrong as I am measuring the socket and not a collet. My reference points could be off.


Anyone here with one similar that can point me in the right direction?

It sure looks like a Jacobs tap chuck on it. What are the dimensions you are getting?
 
I think I got it figured out. I was misunderstanding the the angle dimensions on the chart in the original link I posted. The tapping head came with a flex collet in it, but it was in pieces. I cobbled it back together and remeasured it. Looks like the J44x series collets will fit. The measurements came out almost exact.

I do appreciate your help.
