MT2 to R-8 adaptor - CNCzone.com-The Largest Machinist Community on the net!

Is there such a thing as a MT-2 to R-8 adaptor? I just bought a Bridgeport Mill with a MT-2 spindle and I already have a ton of R-8 tooling. Need to mate the two up. How can I do it?
Thanks,
Barney

Change the spindle or remove the spindle and machine the nose to R8 spec.

MT taper is dangerous for milling with. MT taper is not designed to handle side loads.

If you made a custom adapter it would be 6" long and would take 5 minutes to change tools.

Or you can tool up with new tooling, but you will still have a poor tooling seat.

DareBee...Thanks, I was kind of thinking along those lines too....I'll probably start taking the spindle out in the next week and see what I can do about machining to R-8.

It's easy to go the other way around though. I have an R8 that has an MT2 hole that I use with my chuck for drilling.
