On the 12 speed drill/mill I used to have, I used a "pickle fork" (automotive ball joint separator) to pop its MT2 toolholders out. Having a drill press based head, it only had weedy sub-1/4" metric drawbar which was useless for driving the tapers out. Making a fork with a wider slot for MT3 wouldn't be difficult. I bought mine at Harbor Freight for cheap $. --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
