Review on Adapter，Spindle Adapter，Morse Reducing Adapter， Machines by Dee Rawls

The inner cone of the MT4-MT2 adapter is at least 1/2 inch smaller. This means that the standard length MT2 cone comes out of the ground before it sits in place. The only way to use an adapter is to cut something off the end of your MT2 cone. This will seat it all the way, but then the back of the MT2 cone won't match the slot on the adapter so you can't separate them with a cone mandrel like you should be able to. Save some more money and buy another one.
