PushPull Tapper Three types displayed with differences

[jjr2001]

Here is the 4100. Just that same old gray color. Looks a bit Navy to me. I like it.
It was my first and the one that got me started looking for it's cousins!

Big difference is the 1/4" input shaft. Not changeable like the other two.
It works fine but is a bit long..

The nose on this one has a 1/2-20 thread so it is easy to put on a chuck.
The aluminum nose piece on this one is frozen in place. It may be hiding a
morse taper under it but this one is not coming off.

Best practice for this tool in my thinking would be to get a small dedicated drill press with
maybe say a MT2 or MT3 spindle. Then get an Morse arbor that fits that drill press with
a 1/2-20 threaded end. Now if you can find a PushPull Tapper with collets you have a
dedicated tapping setup for small sizes up to 5/16". By eliminating the original DP chuck
you will gain head space and a shorter tool string.

Next option is to buy a Supreme Versatapper and use it on your drill press.
